  MAJOR FEATURES & CHANGES
============================

Change 3836829 by Ben.Marsh

	UBT: Fix ability to precompile plugins from installed engine builds.

Change 3839519 by Ben.Marsh

	UBT: Simplify configuring bPrecompile and bUsePrecompile settings for modules. Each rules assembly can now be configured as installed, which defaults the module rules it creates to use precompiled data.

Change 4042043 by Steve.Robb

	GitHub #4705 : Added weak lambda's for delegates and multicast delegates.

Change 4042056 by Robert.Manuszewski

	Optimized Mark Phase of GC by up to 10ms by making it run in parallel and removing a huge array presize which we didn't need.

Change 4042104 by Robert.Manuszewski

	Set the minimum GC cluster size to 5 so that GC doesn't have to process micro clusters which are more expensive than processing individual objects

	+ Exposed the minimum cluster size to ini and project settings as gc.MinGCClusterSize
	+ Added the ability to sort clusters by name/object count/mutable object count/referenced clusters count when dumping them with gc.ListClusters command

Change 4042377 by Robert.Manuszewski

	Reworked how GC and other threads (ALT specifically) interact - GC will now notify the ALT it wants to run and ALT will immediately try to finish its current work to allow that. Also the entire ALT tick is now protected against GC running at the same time to improve ALT stability.

	+ added gc.ForceCollectGarbageEveryFrame console variable that triggers a forced GC every frame

Change 4042427 by Robert.Manuszewski

	Changed FGCCSyncObject to use events when waiting for GC to finish so that it doesn't spin on non-game threads when GC is running

Change 4042482 by Robert.Manuszewski

	Unhashing unreachable objects (ConditionalBeginDestroy) will now also be done incrementally, just like the purge phase of Garbage Collection

Change 4042635 by Robert.Manuszewski

	Fix for a potential assert when incremental purge garbage is pending and something forces a full purge

Change 4044092 by Steve.Robb

	Fix for forward declared CoreUObject weakobject types in delegates when building in Clang.

Change 4044102 by Robert.Manuszewski

	Fix for a possible hang when worker threads are preventing GC from running and something is later trying to FlushAsyncLoading with the Async Loading Thread enabled

Change 4044113 by Steve.Robb

	Another Clang fix.

Change 4044160 by Robert.Manuszewski

	Disregard For GC pool will now be enabled by default in cooked builds

Change 4044287 by Steve.Robb

	Typo fix.

Change 4047723 by Graeme.Thornton

	TBA: Fixes for import/export name cache and object resolving

Change 4048015 by Graeme.Thornton

	TBA: Weak/Soft/Lazy pointer serialization changes

	* Remove FWeakObjectPtr::Serialize, move it's logic into, and replace usages of with calls to, FArchiveUObject::SerializeWeakObjectPtr(). Ensures that something is always sent to the archive so that structured archives can be kept happy in the future.
	* Added Weak/Soft/Lazy pointer handling to the structured archive slot interface and all the formatters. Binary formatters just forward the call onto their inner and text archives store as a string path reference.
	* FArchiveUObjectFromStructuredArchive caches all these pointer types and stores indices in the binary block, same as with a UObject*. All pointers are then forwarded to the underlying formatter in one go on finalization.

Change 4048021 by Steve.Robb

	Fix for binding an unbound TFunction to another TFunction with a different signature.  Also all null pointers now count as unbindings, not just nullptr.
	TIsMemberPointer added.
	TIsATFunction and TIsATFunctionRef renamed to remove the 'A's.

Change 4048544 by Robert.Manuszewski

	Fixing ConditionalBeginDestroy profiling after changes to incremental CBD.

Change 4051028 by Graeme.Thornton

	TBA: ArchiveFromStructuredArchive adapter uses Inner to determine if it is outputting to text, and sets it's own ArIsTextFormat to false

Change 4051056 by Graeme.Thornton

	TBA: High level tagged property / UObject base class text serialization
	 - UObject serialize converted to structured archive
	 - Properties written to text individually with text tags, and then binary adapted values
	 - Only saves, doesn't load

Change 4051111 by Graeme.Thornton

	TBA: Temporarily disable loading of text assets until tagged property serialization path is fixed up

Change 4051154 by Graeme.Thornton

	TBA: Convert a few uobject serializers to structured archive format for example purposes

Change 4051181 by Graeme.Thornton

	TBA: Added default structured archive implementation of SerializeItem to UProperty, which just calls the FArchive version on an FArchiveUObjectFromStructuredArchive adapter. Implemented structured archive SerializeItem for UArrayProperty

Change 4051197 by Graeme.Thornton

	TBA: ObjectProperty text serialization

Change 4051216 by Graeme.Thornton

	Restored a modified FWeakObjectPtr::Serialize function to keep backwards compatibility in code I don't have access to.

Change 4051261 by Graeme.Thornton

	TBA: Convert UMetaData to structured archive

Change 4051374 by Steve.Robb

	Incorrect assert removed.

Change 4051562 by Robert.Manuszewski

	Adding stats for the new GC internal functions

Change 4051614 by Graeme.Thornton

	TBA: Removed UProperty::SerializeItem(FArchive, ...) and replaced with UProperty::SerializeItem(FStructuredArchive::FSlot, ...). Fixed up most of them to work properly and added adapters in for any that were non-trivial.

Change 4052512 by Graeme.Thornton

	TBA: Temporary workaround for softobjectptr and lazyobjectptr uproperties not serialization anything when they know the archive is a reference collector. They should always be serializing their pointers and letting the underlying archive itself ignore them.

Change 4053917 by Robert.Manuszewski

	Clustered objects from clusters that are no longer reachable will now be marked as unreachable immediately when gathering unreachable objects

Change 4053919 by Robert.Manuszewski

	Added the ability to disable incremental BeginDestroy in ini/project settings

Change 4055518 by Daniel.Lamb

	Fixup for deterministic audio generation issue.
	Submitted on behalf of Rich.Whitehouse

	#jira nojira
	#test prefilght automated test.

Change 4056854 by Graeme.Thornton

	TBA: Added a test asset to EngineTest which contains all the different property types and test cases.

Change 4056858 by Graeme.Thornton

	TBA: Updated USetProperty to proper structured archive usage

Change 4056872 by Graeme.Thornton

	TBA: Add map property field to test object

Change 4056873 by Graeme.Thornton

	TBA: Convert UMapProperty to full structured archive

Change 4056994 by Graeme.Thornton

	TBA: Converted FText over to structured archive. Implemented saving, but not loading.

Change 4059728 by Ben.Marsh

	UBT: Add support for using adaptive non-unity builds when the engine and project are in separate repositories.

Change 4059805 by Graeme.Thornton

	Fixed typo in text serialization. Fixes CIS automation test errors

Change 4060007 by Graeme.Thornton

	TBA: FArchiveFromStructuredArchive will now access it's host slot lazily, i.e. only when a value is actually written to the archive.

Change 4060092 by Stefan.Boberg

	Added optimized Windows console window output path to GenericConsoleOutput since this slowed down cooking considerably (2 minutes spent in wprintf alone for one large dataset)

	When stdout is attached to a console we use the WriteConsoleW function instead of wprintf since the latter is very slow especially in unbuffered mode which the engine currently configures for stdout (see setvbuf call in LaunchEngineLoop.cpp).

	At some point we should reconsider this buffering policy since it's likely to slow down other platforms as well but I wanted to do a safe change for now as I don't yet fully understand why the setvbuf call is there in the first place.

Change 4060108 by Stefan.Boberg

	Introduced some additional target platform utilities to help with asset cook optimizations

	* We now assign each ITargetPlatform a zero-based ordinal value
	* Introduced FTargetPlatform and FTargetPlatformSet types to help store platform references and platform sets efficiently.

	These are not currently used in the engine but are designed to replace the existing ITargetPlatform/string/FName representations in the cooking data structures.

Change 4060143 by Graeme.Thornton

	Undo //UE4/Dev-Core/Engine/Source/Runtime/... changelist 4060007

	Needs some other changes that I haven't checked in yet...

Change 4062432 by Ben.Marsh

	Fix error message when enumerating P4 changes.

Change 4062648 by Ben.Marsh

	Add missing p4 integration action.

Change 4063620 by Graeme.Thornton

	Integrated a fix from UDN where the engine would crash when trying to load a very small encrypted file (<16bytes) from a pak file, where the read address wasn't already aligned to the AES block size.

	(https://udn.unrealengine.com/questions/431989/crash-while-reading-a-very-small-file-in-encrypted.html)

Change 4066963 by Robert.Manuszewski

	Fixing GC cluster verification code reporting false positives when a cluster is referencing another cluster through 'mutable' objects list.

Change 4067133 by Robert.Manuszewski

	Changed log verbosity when reporting individual cases of GC cluster assumption violations as they are followed by an asser anyway and this way we get the chance to see all issues before we assert at the end of these checks.

Change 4067443 by Steve.Robb

	FString can now be constructed from any char pointer type and length.

Change 4068156 by Steve.Robb

	Fix necessary because of FString constructor change in CL# 4067443.

Change 4070258 by Graeme.Thornton

	Fixes for VSCode

Change 4070372 by Graeme.Thornton

	TBA: Script struct serialization to structured archives

Change 4071913 by Ben.Marsh

	Move bulk of the code for UnrealPak into an engine developer module, so it can be used in the editor.

Change 4071914 by Ben.Marsh

	Missing files.

Change 4071937 by Ben.Marsh

	Missing header.

Change 4072015 by Ben.Marsh

	Fixes for compiling PakFileUtilities as part of the editor.

Change 4072826 by Steve.Robb

	TBitArray::Reserve() added.
	TBitArray::Add() overloaded to allow adding multiple bits.
	TSparseArray::Reserve() optimized to call the overloaded Add().

Change 4073271 by Daniel.Lamb

	Fixed add patch tier in project launcher passing the wrong commandline option to UAT.

	#test none

Change 4074708 by James.Hopkin

	#core Removed redundant Casts

Change 4074763 by Steve.Robb

	Fix for TSparseArray::Reserve() size.

Change 4076063 by Ben.Marsh

	Add an "UnrealPak" commandlet with the same functionality as the standalone UnrealPak program. Invoke by running the editor with -run=UnrealPak and the standard UnrealPak commandline options.

Change 4077064 by Robert.Manuszewski

	Fixing compile error in PakFileUtilities

Change 4077144 by Graeme.Thornton

	TBA: TextAssetCommandlet improvements

	* Collect lists of broken assets during roundtrip tests and print a summary of packages that failed each phase at the end
	* After resaving as text, load the file back as a plain JSON hierarchy to ensure the output was valid

Change 4077412 by Ben.Marsh

	Set the correct exit code for UnrealPak. Should return 0 on success, not 1.

Change 4077760 by Graeme.Thornton

	TBA: Loading fixed for tagged property serialization

	Includes conversion of all UProperty::ConvertFromType() and SerializeFromMismatchedTag() functions to use structured archives

	Lazy initialization of FArchiveFromStructruredArchive when loading, to support the possibility of an adapter being create around an object property serialize call to its inner UStruct, which then decides not to do anything and return false. Stops the ArchiveFromStructuredArchive from consuming the slot and getting upset later on when we try to serialize normal tagged properties from it.

	Disabled lazy bulk data loading from text assets. Requires a bigger change to make it work.

	Added some debug checks to json input formatter which track the current value stack size when a new object is pushed onto the stack, and makes sure that the stack has returned to the same size when the object is popped. Catches cases where we unpack an array/stream to the value stack but then don't consume all the items.

Change 4078800 by Ben.Marsh

	Change UAT to using the editor's UnrealPak commandlet rather than invoking the standalone UnrealPak executable. To improve performance when building several PAK files, also add a new -batch=<file> command which reads commands to execute in parallel from a text file.

Change 4079745 by Graeme.Thornton

	TBA: Migrated a couple of UObject Serialize functions to FStructuredArchive (SoundCue / MaterialExpressions / Editor strip flags)

Change 4079847 by Graeme.Thornton

	TBA: Add 'FindMismatchedSerializers' mode to text asset commandlet, which dumps out a list of all UClasses which don't have the CLASS_MatchedSerializers flag, meaning we can't guarantee the have Serialize functions for FArchive AND FStructuredArchive, therefore we can't use the new structured archive based serialize path. Should only ever be native instrinsic classes as UHT takes care of all other cases.

Change 4079925 by Ben.Marsh

	Fix incorrect assignment when deriving name for chunked pak file.

Change 4080214 by Ben.Marsh

	Move the ThreadPoolWorkQueue class into DotNETUtilities so it can be used by other projects.

Change 4082394 by Graeme.Thornton

	CIS fix for variable shadowing warning

Change 4082583 by Ben.Marsh

	Add a IBinarySerializable interface for types that support reading from a BinaryReader and writing to a BinaryWriter. Implementing IBinarySerializable implies a constructor taking a BinaryReader argument is available for deserializing.

Change 4082652 by Ben.Marsh

	Fix FileReference.Directory not returning a directory with a trailing backslash for files in the root directory.

Change 4082755 by Graeme.Thornton

	Fixed an erroneous usage of TUniquePtr<uint8>as a pointer to a uint8 array when creating pak files. Caused a crash when compression was enabled, and has probably surfaced because pak generation is now done by an editor commandlet rather than a standalone program.

Change 4082756 by Graeme.Thornton

	Fixed some incorrect documentation for pakfile compressed chunk headers

Change 4082883 by Graeme.Thornton

	Static analysis warning fix

Change 4082912 by Ben.Marsh

	Move ExceptionUtils into DotNETUtilities.

Change 4085291 by Graeme.Thornton

	TBA: In the Json output formatter, write float and double values out with enough precision for successful roundtripping. Added some debug only code which will immediately reconvert the string back to its original value and compare the the input

Change 4085523 by Graeme.Thornton

	TBA: Remove only explicit usage of DECLARE_FSTRUCTUREDARCHIVE_SERIALIZER. Should only be used from UHT generated code.

Change 4086037 by Robert.Manuszewski

	Fix for a potential race condition when two threads want to acquire GC lock

Change 4088655 by Graeme.Thornton

	Pak creation now uses the bEnablePakSigning setting from the crypto config json file

Change 4091474 by Steve.Robb

	Fix for TStaticBitArray::FindFirstSetBit() and TStaticBitArray::FindFirstClearBit().
	Unused variables removed.

Change 4093632 by Steve.Robb

	CIS fixes.

Change 4093656 by Graeme.Thornton

	Build fix

Change 4093744 by Ben.Marsh

	Allow per-chunk settings for whether to enable compression in UnrealPak.

Change 4099712 by Gil.Gribb

	UE4 - Fixed rare case where insufficient space was preallocated for cooldown ticks.

	#jira UE-59686

Change 4099912 by Stefan.Boberg

	Cooking timer optimizations:

	- Replaced data structures for FScopeTimer and FHierarchicalTimerInfo. Previous implementation used FString for many things and caused *lots* of heap and string concatenation activity. Replaced with a compile-time node id (using __COUNTER__) and raw string literals.
	- Removed PERPACKAGE_TIMER support (was disabled by default and was difficult to test)
	- Made it possible to toggle OUTPUT_TIMING and ENABLE_COOK_STATS independently
	- Removed some extremely tight timers because the overhead from calling QPC significantly exceeded the measured code

	This change shaved some 15% off a clean cook of Fortnite WindowsClient (en) with fully populated local DDC

Change 4100519 by Stefan.Boberg

	Quick fix for Linux build issue introduced in 4099927

Change 4105327 by Stefan.Boberg

	Cooker: Changed FHierarchicalTimerInfo so it uses a linked list for tracking child nodes, to be able to deal with any child count. Previously we assumed there would never be more than 9 children but it turns out there are cooker modes that need more.

	Fixes check when using -FullLoadAndSave to cook

Change 4105448 by Stefan.Boberg

	- Fixed Linux build warning re: member initialization order
	- Also eliminated OUTPUT_HIERARCHYTIMERS/CLEAR_HIEARCHYTIMERS macros (plain functions are fine)
	- Moved finishing-up code for FullLoadAndSave() to TickCookOnTheSide() call site to improve timer output. Previously some of the scopes would not have been closed before printing and thus the output was misleading.

Change 4109031 by Ben.Marsh

	Attribute-driven Perforce wrapper (old Epic Friday project). Offers a more complete implementation than the current P4 wrapper in UAT without requiring any platform-specific libraries. Uses the Python binary output for parsing.

Change 4109588 by Ben.Marsh

	UBT: Add extension methods for serializing a nullable type to a BinaryReader/BinaryWriter.

Change 4109595 by Ben.Marsh

	Missing project file for DotNETUtilities.

Change 4110724 by Stefan.Boberg

	Removed annotation map locking in UObjectMarks, eliminating around one minute (~3.5%) from Fortnite cook time.

	The locking was redundant since the annotation maps are managed per thread anyway.

Change 4111304 by Ben.Marsh

	UAT: Add support for setting a status message through the log class. Allows writing transient messages (eg. progress messages) which will be cleared out before writing other messages. Best used through the LogStatusScope class, which can set a status message for the duration of a using() block.

	As part of this change, the console no longer has to be added as a dedicated trace listener. Since we already special-case this listener when formatting log output, it's easier to just keep the implementation separate to the other trace listeners.

Change 4112708 by Steve.Robb

	Fix for TBitArray::MaxBits in assignment.

Change 4114133 by Stefan.Boberg

	Tweaked how low-level memory (LLM) tracker is implemented to reduce overheads.

	Previously FMemory functions would acquire the LLM singleton and call OnLowLevelFree/OnLowLevelAlloc etc which would check the bIsDisabled flag and early out if it was set. Due to how frequently these functions were called this ended up costing quite a bit.

	- This change makes the flag a static member variable instead of a member variable and therefore enables a simpler early-out to be implemented.
	- The singleton getter is also simplified to avoid hitting the threadsafe singleton construction path on every call.
	- The enable flag is no longer TAtomic - this also incurs extra overhead for no clear benefit

	Shaves approximately 3.5% (one minute) off a Fortnite cook test scenario (using -FullLoadAndSave)

Change 4115010 by Robert.Manuszewski

	Fixing CIS

Change 4115249 by Robert.Manuszewski

	Fixing async loading code asserts when exiting game very early due to an error

	#jira UE-56267

Change 4117091 by Ben.Marsh

	Prevent doubled-up lines when writing status updates with console log verbosity.

Change 4117207 by Ben.Marsh

	UGS: Do not include executables in diagnostics zip file, and ignore "no such files" error when cleaning workspace.

Change 4119175 by Ben.Marsh

	UGS: Fix crash writing version files when directory does not already exist.

Change 4119987 by Ben.Marsh

	UGS: Show a dialog box while the launcher is updating executables from Perforce, which allows cancelling the operation if necessary. Allow setting the username on the settings window, and prompt for login credentials if necessary. Should prevent situations where users have to update settings from the command prompt.

	Holding down shift during launch now shows the settings dialog rather than an immediate prompt to launch the unstable version (unstable version is shown as a checkbox on this dialog).

Change 4119991 by Ben.Marsh

	Update version number for UGS launcher to 1.13.

Change 4121943 by Robert.Manuszewski

	Don't use FArchiveAsync2 for reading packages with non-async path in editor builds as its performance is worse than the standard archive's (saves about 1 minute when doing larger cooks and 7 seconds when loading into PIE)

Change 4122592 by Steve.Robb

	GitHub #4762 : Improve wording and grammar of Math comments
	Also includes improved accuracy in FMath::ComputeBoundingSphereForCone().

Change 4122819 by Stefan.Boberg

	Don't call CreateDirectory redundantly when opening files for writing using FFileManagerGeneric::CreateFileWriter

	This change avoids calling IPlatformFile::CreateDirectoryTree if possible since this is a very expensive function especially for deep hierarchies as it performs directory creation from the root directory onwards instead of from the leaf downwards. That function should also be fixed but this change improves performance in the meantime.

Change 4122872 by Stefan.Boberg

	CreateDirectoryTree now creates directories leaf-to-root instead of the other way around. This is much more efficient since we don't spend time on system API calls for directories which already exist. This accounted for a very large amount of CPU time in cooking as the full target file directory hierarchy would be "created" for every single output file.

Change 4123109 by Stefan.Boberg

	- Disable overlapped I/O in editor / cooker. Synchronous I/O reduces the number of syscalls and Windows performs prefetching on our behalf anyway for sequential reads
	- Eliminated syscall which was issued for every write to update cached file size -- since we're the only writers to the file (file access allows read sharing at most) we can authoritatively update the file size on write completion

Change 4123455 by Ben.Marsh

	PR #4775: New build param PCHMemoryAllocationFactor to set /Zm VS build param. (Contributed by lucaswall)


Change 4124207 by Ben.Marsh

	UBT: Remove some unnecessary indirection for generated code paths.

Change 4124217 by Ben.Marsh

	UBT: Remove another unused variable from UEBuildModuleCPP.

Change 4124377 by Stefan.Boberg

	In IPlatformFile::DeleteDirectoryRecursively, attempt to delete file first and if it fails clear the readonly flag and try again

	Previously there was a call to clear the readonly flag for every deleted file and this is a waste of resources 99% of the time. The SetFileAttributes call accounted for a significant amount of time during cooker sandbox directory deletion

Change 4125071 by Stefan.Boberg

	Some tweaks to FQueuedThreadPoolBase scheduling and memory management

	- Explicitly pass in false for TArray::RemoveAt(..., bool bAllowShrinking) argument to prevent memory reallocation when arrays are drained and inevitably repopulated shortly afterwards
	- Use a MRU strategy instead of LRU when picking a thread to wake up. The MRU thread is the most likely to have a 'hot' cache for the stack etc. Picking from the back of the array also happens to be cheaper since
	no memory movement is necessary when RemoveAt is called. (This was the strategy in place before CL2600362 which seems to have changed it unintentionally)
	- Release lock as soon as a thread has been chosen, before asking the worker thread to wake up and do the work

Change 4126132 by Ben.Marsh

	UAT: Detect when stdout is redirected and prevent using backspace characters to move the cursor.

Change 4126867 by Graeme.Thornton

	TBA: Fix tagged binary formatter

Change 4127010 by Robert.Manuszewski

	AnimScriptInstances created at runtime will now also be added to the owning omponent's cluster to avoid GC issues.

Change 4127932 by Ben.Marsh

	WorkspaceTool: Reduce unnecessary logging of status messages when console output is not redirected.

Change 4129050 by Ben.Marsh

	UGS: Check for NET Framework 4.5 being installed before running the installer. Also fix warning trying to kill existing UGS instances before upgrade.

Change 4129459 by Graeme.Thornton

	TBA: TextAssetCommandlet - When outputting converted assets to an output path, replicate the workspace relative path in the output directory

Change 4129515 by Graeme.Thornton

	TBA: Add EnterRecord overload that allows outputting of available field names when loading.

Change 4129517 by Graeme.Thornton

	TBA: Tagged properties are written out as named fields on the "Properties" record, rather than as a stream with a null tag at the end

Change 4129518 by Graeme.Thornton

	TBA: Added a local const bool to allow easy hacking out of text asset loading support

Change 4129558 by Graeme.Thornton

	TBA: Build fix for textasset-less configs

Change 4129614 by Ben.Marsh

	UGS: Main window is now restored to normal size when activated by clicking on the tray icon.

	#jira UE-60490

Change 4129618 by Ben.Marsh

	UGS: Speculative fix for unreproduced exception accessing disposed window while shutting down.

Change 4131936 by Robert.Manuszewski

	Removing some WIP code accidentally checked in with CL #4121943

Change 4133490 by Ben.Marsh

	UGS: Allow the $(Change) variable to be used in more places than just the context menu.

	#jira UE-60573

Change 4133550 by Ben.Marsh

	UGS: Setting for whether or not to use incremental builds is now exposed through the variable "$(UseIncrementalBuilds)" for use by custom build steps.

	#jira UE-60554

Change 4133681 by Ben.Marsh

	UGS: A per-project list of folders and extensions to be deleted by default when running the 'clean workspace' tool can now be specified through the <ProjectDir>/Build/UnrealGameSync.ini file. Settings may be specified for an individual branch (via a category with the depot path to the project) or for wherever the project is currently open (via the [Default] category).

	The SafeToDeleteFolders list specifies a substring that will be checked against folder paths. Anything containing this folder will be marked as safe for delete by default.

	The SafeToDeleteExtensions list specifies a list of extensions for files that can always be deleted.

	Example:

	 [Default]
	+SafeToDeleteFolders=/MyGame/Test/
	+SafeToDeleteFolders=/DataService/
	+SafeToDeleteExtensions=.xx1
	+SafeToDeleteExtensions=.xx2

	#jira UE-60575

Change 4135449 by Ben.Marsh

	Fix allowing use of Job objects on Windows platforms (debug code submitted by mistake)

Change 4135730 by Ben.Marsh

	UBT: Plugins can now be enabled and disabled from the .target.cs file (for targets that do not use the shared compile environment), by compiling the list of enabled/disabled plugin names into the Projects module.

Change 4135823 by Ben.Marsh

	UBT: Remove legacy code to handle disabling optional plugins; now that this is compiled into the target, it will work for any plugins we choose.

Change 4135945 by Ben.Marsh

	UBT: Fix error running programs with no explicitly enabled or disabled plugins.

Change 4137207 by Ben.Marsh

	UGS: Align all badges with the same name, to make it easier to see which CIS steps are being run. Allow overriding the slot taken by a particular badge by calling it "SlotName:LabelName".

Change 4137311 by Stefan.Boberg

	Removed child cooker support.

	In practice it is not a useful feature as it provides no performance improvement (quite the opposite in fact) and adds testing and maintenance complexity.

Change 4137393 by Ben.Marsh

	UGS: Fix display of multiline errors in the status panel.

Change 4141708 by Steve.Robb

	GitHub #3631 : Incorrect default argument in WeakObjectPtrTemplate

	#jira UE-45490

Change 4146655 by Stefan.Boberg

	Removed FullGCAssetClasses logic - no longer necessary nor useful

Change 4147318 by Ben.Marsh

	UGS: Compress build badges in a column if it shrinks below the size that they would be visible.

Change 4148207 by Ben.Marsh

	UGS: Added support for showing the latest completed build from a specific list of badges in the status panel. To declare a badge as one that should appear in the status panel rather than the CIS column, add it to the project's UnrealGameSync.ini in the project or [Default] section like so:

	+ServiceBadges=RoboMerge

Change 4148282 by Stefan.Boberg

	Fixed bug in UCookOnTheFlyServer::GetCookOnTheFlyUnsolicitedFiles - UnsolicitedFiles should be passed by reference not by value

Change 4148344 by Stefan.Boberg

Change 4190082 by Ben.Marsh

	Fixes to allow enabling edit and continue for Windows builds. Have experienced quite a few VS crashes when testing it in editor; not yet recommended for general use.

	- Allow edit and continue for any configuration, not just debug.
	- Fixed PDB errors compiling files that use a shared PCH with edit and continue enabled. Path to the generated PDB file was using the wrong directory.
	- Removed code that tracks PDB output files, since they're modified multiple times during a build.
	- Enable debug information when compiling generated CPP files, since it causes errors if the shared PCH PDB doesn't have the same option.
	- Disable support for remote execution of steps that modify the PDB, since the same file has to be modified many times. Remote execution causes the PDB files to be corrupted. Unfortunately, this makes E&C builds significantly slower.

	* Programs under the engine directory can now use a shared build environment, so that building with a project file does not cause output binaries to be output to the project directory.
	* UnrealPak is now always built by default when packaging

	UBT: Change the order in which Visual C++ toolchains are enumerated to prefer full releases over preview releases.

Change 4223318 by Ben.Marsh

	UBT: Add a build setting which allows creating a dedicated PCH for every file that's excluded from the unity working set (disabled by default). Improves iteration times when working on individual cpp files, but slows down iterating on header changes (and can take a lot of disk space for large changes).

	Dedicated PCH contains all includes scraped from the top of each cpp file, until a non-#include directive is encountered.

Change 4223401 by Ben.Marsh

	UBT: Add an option to automatically enable edit and continue for files in the adaptive non-unity working set. E&C doesn't seem very useful for UE4 projects right now; compile time is comparable to regular build times, but it can take several minutes to apply code changes for large projects.

Change 4223899 by Ben.Marsh

	UBT: Fix loading XML config files on Mono; Type.GetField(Name) does not seem to return values unless binding flags are specified.

Change 4224637 by Ben.Marsh

	Add a "SupportedPrograms" field to plugin descriptors, which allows plugins to declare which plugins they support independently of individual modules. Programs now respect the "bEnabledByDefault" setting in plugins.

Change 4234688 by Ben.Marsh

	UBT: Simplify handling of installed/precompiled builds. Settings for whether a folder is installed/read-only or not is now stored on the RulesAssembly instance, allowing multiple things to be configured separately and stacked together (eg. engine/enterprise/project). RulesAssembly.IsReadOnly() allows determining if a flie can be modified or not and replaces many previous IsXXXInstalledCalls(), and traverses the chain of assemblies.

Change 4234711 by Ben.Marsh

	UBT: Runtime dependencies can now be copied to output directories as part of the build. When adding a runtime dependency, an optional source location can be specified to copy from. Both the source and target paths can use variables can be used as part of the path, eg. $(OutputDir), $(ModuleDir), $(PluginDir).

Change 4274823 by Ben.Marsh

	Add the -VersionCookedContent argument to disable the -unversioned parameter on the cooker command line.

Change 4275838 by Ben.Marsh

Change 4275913 by Ben.Marsh

	Add a dummy exported symbol to the XGEController module, to fix build errors due to missing .lib file when it's built with WITH_XGE_CONTROLLER = 0.

Change 4284161 by Ben.Marsh

	Allow mirroring Oodle files to remote Mac.

Change 4074774 by Steve.Robb

	https://blogs.msdn.microsoft.com/oldnewthing/20151008-00/?p=91411

Change 4091456 by Steve.Robb

	Unification of all platforms' FMath::CountTrailingZeros() and FMath::CountLeadingZeros() for both 32-bit and 64-bit.

Change 4156437 by Ben.Marsh

	Lots and lots of fixes compiling for Clang on Windows.

	Editor now compiles cleanly without warnings, but crashes on startup due to error in intrinsics test. Disabling that runs further, but crashes accessing freed memory. Switching to the ANSI allocator runs further, but crashes in Slate after the splash screen and before the editor window opens. // TODO!

	* Switching between Clang/ICL/VS2015/VS2017 is now supported through the same mechanism as switching Visual Studio versions, without requiring any source level changes. To use Clang, set WindowsPlatform.Compiler = WindowsCompiler.Clang from a .target.cs file, or set <WindowsPlatform><Compiler>Clang</Compiler></WindowsPlatform> from BuildConfiguration.xml. To pick a specific toolchain version, set WindowsPlatform.CompilerVersion.
	* Clang is now supported through AutoSDKs; will be added to CIS.
	* The Samples/Sandbox/Clang project forces Clang to be used from its target.cs file, and allows easily building all editor modules and plugins with Clang on Windows.
	* UnrealMathSSE intrinsics have been re-enabled for Clang due to missing functions from the UnrealMathFPU implementation, but causes failure in tests at startup.
	* SSE4_CRC32() is disabled in D3D12Pipelinestate.cpp, since intrinsics are only allowed if enabled for the whole target (rather than being used in specific functions due to runtime checks)

Change 4157389 by Ben.Marsh

	Few more fixes for compiling the editor with Clang.

Change 4183911 by Ben.Marsh

	Fixes to support incremental linking on Windows. Does not seem to have any net benefit right now; may improve once minimal rebuild is enabled.

	* Incremental linking no longer forces PDB files to be enabled for source files.
	* Actions can specify specific files to be deleted before each build. Code to forcibly delete PDB files has been moved to the MSVC toolchain.
	* Unused libraries produced by the cross-referenced link are no longer added as build products, since (a) deleting them breaks dependency checking for incremental linking and causes a full link, and (b) not deleting them breaks UBT dependency checking and causes actions to be run over and over again.
	* Icon update is disabled for Windows when incremental linking is enabled.
	* Removed rarely-used setting to always delete produced items before each build.

Change 4184311 by Ben.Marsh

	UGS: Added a dialog which shows all the required platform SDKs for a branch, linked from the status panel in UGS.

	The llist is configured via the UGS config file submitted to Engine/Programs/UnrealGameSync/UnrealGameSync.ini (and may be overridden by the project config file if necessary):

	    [Default]
	    ; Set this to a network share which contains the SDK installers for your site
	    SdkInstallerDir=

	    ; All the required SDKs for the current version of the engine
	    +SdkInfo=(Category="Android", Description="NDK r21", Browse="$(SdkInstallerDir)\\Android")
	    +SdkInfo=(Category="Windows", Description="Visual Studio 2017")
	    +SdkInfo=(Category="Windows", Description="Visual C++ Toolchain 14.13.26128")
	    +SdkInfo=(Category="Windows", Description="Windows SDK 10.0.16299.0")

	Similar entries for console platforms are added in console subdirectories. Each entry may contain an Install="Foo.exe" and/or Browse="C:\Foo" style attribute, specifying the path to an installer to run or directory to open in explorer respectively.

	The SdkInstallerDir setting is used as a base directory for the default installers, seen above for Android. Licensees may override this with a network path specific to the site that UGS is being deployed to (either in this file, in a project specific config file, or in a Engine/Programs/UnrealGameSync/NotForLicensees/UnrealGameSync.ini file).

Change 4200452 by Ben.Marsh

	UBT: Change DebugGame configurations to output a separate executable rather than requiring a -Debug argument at runtime. Previous behavior was a common source of errors.

	Engine modules are still shared between Development and DebugGame, but the launch module sets a flag in Core on startup indicating the game configuration.

Change 4206189 by Ben.Marsh

	UBT: Simplify logic for precompiling binaries.

	* Target no longer has separate list of "precompile only" binaries or modules. New -AllModules option allows adding every module to a target, which can be used with -Precompile and -NoLink to precompile object files for monolithic builds.
	* Precompiled file lists have been removed from target receipts.
	* The manifest now includes all generated headers and precompiled files when run with the -Precompile option.
	* Separate -DependencyList=Foo.txt has been added to write a list of all dependencies required to use precompiled binaries. This file list can be read using the <Tag> task in buildgraph.

Change 4215466 by Ben.Marsh

	UBT: Remove indirect calls to determine extensions for object files and precompiled headers. The toolchain knows the correct convention for the platform.

Change 4215975 by Ben.Marsh

	UBT: Remove telemetry code. This has never proved useful for analyzing performance due to the number of incidental factors that affect build times (eg. number of files being compiled).

Change 4220154 by Ben.Marsh

	Move text-only implementations of FOutputDeviceError back into Core, so we can build command-line applications that don't depend on ApplicationCore.

Change 4224708 by Ben.Marsh

	Add a bCompileAgainstApplicationCore setting to the target rules, which allows compiling out references to the ApplicationCore module (which should only be necessary for applications with a GUI). Removed ApplicationCore from several engine tools and utilities.

Change 4224958 by Ben.Marsh

	Remove CoreMinimal.h includes from Core.

Change 4229059 by Ben.Marsh

	UBT: Remove the UEBuildPlatform.ShouldNotBuildEditor() hook for target platforms. We shouldn't be modifying a target's build environment to disable the editor; it is invalid to build the editor for these target platforms at all, and this is already enforced by the GetSupportedPlatforms() function.

Change 4230508 by Ben.Marsh

	Fixup precompiled header setting for samples and games.

Change 4231457 by Ben.Marsh

	Fix exceptions in log messages having trailing newlines.

Change 4232406 by Ben.Marsh

	UBT: Always force include a PCH for generated code if there's one set; the code may depend on it to compile.

Change 4234177 by Ben.Marsh

	Set up private PCH files everywhere that previously used them.

Change 4235973 by Ben.Marsh

	Change FPlatformMisc::GetEnvironmentVariable() to return an FString() rather than requiring a fixed size buffer to be passed in. Removes references to MAX_PATH.

Change 4238842 by Ben.Marsh

	Add support for paths longer than MAX_PATH in the editor. Requires Windows 10 version 1607, and the functionality to be enabled via a registry key or group policy (see https://docs.microsoft.com/en-us/windows/desktop/FileIO/naming-a-file).

	Only a subset of Win32 functions support long paths (executables can only be started from paths shorter than MAX_PATH, for example).

	* Added a FPlatformMisc::GetMaxPathLength() function to return the maximum length of a path on the current system. On Windows, this returns a different value for systems with long paths enabled to those without.
	* The MAX_PATH define is no longer set by non-Windows platforms. Instead, there is a MAC_MAX_PATH, UNIX_MAX_PATH, etc... for any platform-specific code that still relies on the previous macro.
	* The MAX_UNREAL_FILENAME_LENGTH macro has been renamed to MAX_UNREAL_FILENAME_LENGTH_DEPRECATED
	* The PLATFORM_MAX_FILEPATH_LENGTH macro has been renamed to PLATFORM_MAX_FILEPATH_LENGTH_DEPRECATED.
	* Removed custom resource files for programs, since they are just copies of the base UE4 one (which is used by default anyway). The base UE4 manifest declares support for long paths.
	* Fix 512 character maximum length on editor commands.

	260 character limit remains in place for cooking at the moment (see ContentBrowserUtils.h), until C# staging code supports long paths.

Change 4255042 by Ben.Marsh

	UBT: Remote compilation now uploads the entire workspace to the remote Mac and executes a separate remote instance of UBT rather than synchronizing individual actions. This makes the remote compile codepath much simpler, and removes a lot of special cases that exist to support it previously.

	The list of files to be transferred to the remote are listed as rsync filter rules in Engine/Build/Rsync/RsyncEngine.txt and RsyncProject.txt, which are applied to the root engine directory and project directory respectively. Projects that need to customize which files are uploaded can add their own <ProjectDir>/Build/Rsync/RsyncProject.txt file, which will be included in the filter before the default version.

Change 4260567 by Ben.Marsh

	UAT: Rename CommandUtils.Log to CommandUtils.LogInformation, to avoid conflicts with the underlying Tools.DotNETCommon.Log class.

============================
  MAJOR FEATURES & CHANGES
============================

Change 4112782 by Mitchell.Wilson

	Resaving some cloth assets and fixing material compile warnings.
	#jira UE-59946

Change 4112762 by Max.Chen

	Sequence Recorder: Fix case where first recording is null but there are other valid recordings.

	StopRecording wasn't getting called because the EndPIE delegate wasn't bound since ActorWorld was incorrectly set.

	#jira UE-58688

Change 4112738 by Michael.Dupuis

	#jira none:
	Fixed Editor instance count, to only include placed instances.
	Calling GenerateProceduralContent will no longer automatically remove the current content, as we might want to get the generation for something else than replacing existing data.
	When deleting procedural foliage, we can now specify if we want to rebuild the tree.

Change 4112696 by Matt.Kuhlenschmidt

	Prevent GC of material editor active preview expression

	#jira UE-49777

Change 4112611 by Michael.Dupuis

	- Mirrored from //UE4/Dev-Framework (4111638).

	#jira UE-53747

Change 4112138 by Phillip.Kavan

	Fix UHT warning about duplicating UFUNCTION() meta on nativized child Blueprint classes that override at least one BPIE method from the parent class.

	- Mirrored from //UE4/Dev-Framework (4111613).

	#jira UE-59182

Change 4111630 by Matt.Collins

	#jira UE-59934

	Rolling back the previous integration of CL 4080446

Change 4111526 by Mike.Beach

	Guarding against bad settings pointers internal to Oculus.

	#jira UE-59778

Change 4111525 by Daniel.Wright

	UStaticMeshComponent::PostEditUndo now initializes its UStaticMesh's rendering resources.  This is necessary for cases where the UStaticMesh is in the same transaction (PostEditUndo will be called AFTER the component).  However, when calling UStaticMesh::InitResources we must use a FStaticMeshComponentRecreateRenderStateContext to safely handle any components using the UStaticMesh which are not in the transaction.
	#jira UE-59333

Change 4111518 by Mike.Beach

	Making sure to load the third party dll, and initing Oculus when we querry for Vulkan extensions. Otherwise we end up calling into the OVR plugin before the dll is loaded.

	#jira UE-53643

Change 4111482 by Matt.Kuhlenschmidt

	Fix blend sample context menu appering offset on high dpi monitors

	#jira UE-59925

	Sequencer: Fix dereferencing null pointer - CameraNode

	#jira UE-59347

Change 4111143 by Matt.Collins

	#jira UE-59934

	CL 4107446 from Dev-Rendering.
	Always force a commandbuffer submission during EndFrame.

Change 4111106 by Matt.Collins

	#jira UERNDR-406
	Bringing CL 4104051 from Dev-Rendering (//UE4/Dev-Rendering) to Release-4.20 (//UE4/Release-4.20)

	---
	Some fixes for semaphore handling.

	Moved the completion handler to EndFrame (out of FlushFreeList())

	FlushFreeList() attached a handler to the command buffer that signaled the semaphore. This can be called through RHIFlushResources which will cause a mismatched signal()

	Added BeginFrame/EndFrame to the loop in AddModalWindows so the renderer gets the expected frame delimiters. Removed call to EndFrame from EndDrawingViewport.

	---

Change 4111099 by Ben.Zeigler

	#jira UE-59199 Add enum redirector for CVD_NormalVision, some values map to normal as they were removed
	This is needed because that enum value would have been written into the EditorPerProjectSettings for anyone that modified editor style, and then cause mysterious cook warnings

Change 4111039 by Ben.Zeigler

	#jira UE-59046 Fix it so trying to convert a soft path to hard object ref will throw error during async loading instead of silently failing

Change 4111013 by Steve.Robb

	Fix for adding a new module to a project.

	#jira UE-59770

Change 4110868 by Ben.Zeigler

	#jira UE-59920 Fix several issues where half-connected reroute nodes could break AutoCreateRefTerm and other node expansions if they happened to be late in the nodes array, by always expanding knot nodes first

Change 4110704 by Ben.Zeigler

	#jira UE-56365 Fix k2 node tooltip code to not crash if the node is out of date due to slate updates being a tick behind

Change 4110686 by Andrew.Grant

	Resaved to fix empty engine version warning
	#jira UE-59695

Change 4110466 by Ben.Zeigler

	#jira UE-59908 Change loading screen logo back to one with text baked in and clean up comments
	Delete unused logo images

Change 4110418 by Ben.Zeigler

	#jira UE-58025
	Fix non editor builds

Change 4110258 by Max.Chen

	Sequencer: Fix some erroneous cases in import fbx. In particular, this fixes an issue where importing an fbx onto one node would behave differently if there are multiple nodes in the fbx since it was ambiguous as to which fbx node to map onto the single node in sequencer.

	- Changed import operation to be more explicit - when invoking through the general import fbx menu, all object bindings are mapped onto. When invoking through the context menu, only the selected object bindings are mapped onto.
	- Added a user toggle to match by name only. The default is true.
	- When importing onto a selected node, disable the creation of cameras.
	- Don't set range bounds on imported keys since external packages, ie. maya, most likely only have 1 equivalent infinite section range.
	- Remove any existing sections/keys when importing onto existing tracks.

	#jira UE-59347

Change 4109923 by Michael.Dupuis

	#jira UE-59904: Build tree post Serialize otherwise sometime foliage will be missing

	#jira UE-29618

Change 4109849 by Michael.Dupuis

	#jira none: Removed PRAGMA_ENABLE_OPTIMISATION

Change 4109835 by Lukasz.Furman

	added OnTaskFinished call when behavior tree's subtree is deactivated
	#jira UE-48353

Change 4109829 by Ben.Zeigler

	#jira UE-59909 Add logic so the player cannot be hurt during ShieldNS anim notify by adding and removing a damage immune gameplay effect

Change 4109820 by Michael.Dupuis

	#jira UE-59533: Update the LOD Distribution settings to fix the landscape popping

Change 4109813 by Michael.Dupuis

Change 4109780 by Alexis.Matte

	Add the tps file for the levenshtein distance algorithm
	#jira none

Change 4109542 by mason.seay

	Updated timeline on BP

	#jira UE-29618

Change 4109474 by Marc.Audy

	Fix shadow variable warning

	#jira UE-59895

Change 4109420 by Michael.Dupuis

	#jira UE-58672 : Since it's possible the GetInstanceBasePtr() would not find the base id we hit,  do not assume it must always be valid, and simply skip it instead of crashing.

Change 4109397 by Ben.Marsh

	Speculative fix for exception reading UBT makefiles on Mono. Doesn't seem to be able to deserialize dictionaries with custom comparison functions correctly.

	#jira UE-59222

Change 4109395 by Lauren.Ridge

	Removing legacy uses of GetEditorIcon from UMG
	#jira UE-59038

Change 4109390 by Zachary.Wilson

	Adding alternative ground truth images for AMD on the planar reflection tests. ST_PR00, 03, 04, 05
	#jira UE-59409

Change 4109373 by Michael.Dupuis

	#jira UE-58664
	Restrict the Paint/Unpaint Density to 1.0
	Restrict the Foliage Density type to 10000
	Restrict the Grass Density type to 1000
	Fixed a NAN that could be generated when adding instances
	These settings would still allow to paint ~2 millions instances with the biggest brush and max density per click.

Change 4109348 by Lauren.Ridge

	Removing engine content that used a material attribute layers node inside a material function
	#jira UE-55739

Change 4109296 by Lauren.Ridge

	Fix for crash on adding OnClicked event to button in Widget BP
	#jira UE-59846

Change 4109193 by Matt.Kuhlenschmidt

	Fixed crash when construction scripts are rerun during the details panel calling posteditchange

	#jira UE-59649

Change 4109096 by Thomas.Sarkanen

	Fixed crash when running in standalone editor build using sub-instances that copy properties

	Revamped change as the last one failed Fast Path automated tests. This change limits the property re-find only to cases where we are using sub-instances.
	DestProperty serialization was always a bad idea, this is another artifact of the problem where the property persists but the class it belongs to gets trashed. Re-mapping the property by name to the correct outer fixes this for a minor startup cost.

	#jira UE-59510 - Crash in Standalone When Sub Anim Instance Uses Exposed Variable

Change 4109078 by Ben.Marsh

	Fix warnings building PlatformerGame due to incorrect include path.

	#jira

Change 4109066 by Matt.Kuhlenschmidt

	Prevent alt-f4 during slow tasks as it causes entry into the shutdown sequence at abnormal times

	#jira UE-59866

Change 4109020 by Ben.Marsh

	Fix client targets showing up in packaging menu for installed builds (which don't ship with client binaries).

	(This implementation is a little suspect in general - there is no requirement that client targets are called "*Client.Target.cs", though that is typically the case.)

	#jira UE-59641

Change 4108991 by Martin.Wilson

	Fix crash when trying to extract transform from raw track with no track data.

	#jira UE-58025

Change 4108987 by Martin.Wilson

	Make sure rotations are normalized before creating blended transform

	#jira UE-53971

Change 4108932 by Thomas.Sarkanen

	Back out changelist 4108877

	DestProperty serialization was always a bad idea, this is another artifact of the problem where the property persists but the class it belongs to gets trashed. Re-mapping the property by name to the correct outer fixes this for a minor startup cost.

	#jira UE-59510 - Crash in Standalone When Sub Anim Instance Uses Exposed Variable

Change 4108874 by Thomas.Sarkanen

	Fixed incorrect preview mesh being applied after retargeting

	On first setup, the preview mesh was obtained using a legacy path that didnt use the skeleton fallback

	#jira UE-59636 - When Retargeting Animation, Mesh Set as Preview that Shares Skeleton Isn't Kept

Change 4108834 by Thomas.Sarkanen

	Pressing enter when selecting an object from a Blueprint node now works

	#jira UE-58017 - Enter key does not set chosen asset on some blueprint nodes

Change 4108833 by Thomas.Sarkanen

	Fixed crash caused by retargeting a skeleton when some of its animations are still open

	Firstly we now auto-close all assets that use a skeleton when retergetting instead of popping up a dialog to suggest the user does it.
	Secondly as a safety measure we dont re-use an animation editor if the persona toolkit's skeleton doesnt match.

	#jira UE-58681 - [CrashReport] UE4Editor_Persona!FPersonaToolkit::SetAnimationAsset() [personatoolkit.cpp:211]

Change 4108808 by Dmitriy.Dyomin

Change 4108418 by Mark.Satterthwaite

	Fix Shipping iOS builds.

	#jira UE-59883

Change 4108118 by Alexis.Matte

	Make sure GIsImportingT3D is false when the scene importer open the blueprint editor. This flag force a load of UObject when we do FindObject, which in this case was forcing a load of all blueprints assets.
	#jira UE-59854
	#jira UE-57861

Change 4108059 by Ben.Marsh

	Merge latest UGS fixes (up to 1.140) to 4.20 branch.

	#jira

Change 4107719 by Mark.Satterthwaite

	Duplicate 4107661:

	Refactor the MetalRHI debugging tools to move away from reimplementing the Objective-C protocols to adding separate debugging classes. This makes it easier to build on/for future OSes without having to interpose new functionality we don't yet use.

	#jira UE-59883

Unfortunatly the style set referenced is invalid as this call happens much earlier in the startup than with the game or the editor

	1) Changed GetStyleSetName() - this is not imortant for us so it won't crash there again.
	2) Added a check to see if the menu hasn't been setup correctly - if not initialize - this allows localization and and correct keyboard short cuts in non editor / game builds.
	3) Keep Editor and Game menu startup behaviour the same as before.

	Fix for performance issues with motion trails.

	Found that the main issue was the GetRefTM call.  Refactored the code so that we only call that once per tick, instead of up to  4 times per tick. Also we cache the calculation of the key positions, so we don't need to calculate them again when calculating keys.  Finally the GetRefTM call was recursive which was a decent hint, so we cache out it's parent's first and just get the transform's linearly.

	Also we don't select parents or children to show their trails also, this seemed buggy and possibly very very slow.

	 - Wrapped enum entries may be compared against numbers (even numbers that don't have valid values) via the == and != operators (like IntEnum in Python).
	 - Wrapped enums may now be iterated (like native Python enums).
	 - Wrapped enums now return a length based on their number of entries (like native Python enums).
	 - ScriptName meta-data can now be used with enum entries.

	speculative fix for FSlateMacMenu::UpdateMenu() crashes.  I've not been able to reproduce this.  All the crash call stacks seem to be at shutdown, maybe with the save changes dialogue that would appear after modifications then a CMD+Q.  I can get similar behaviour by adjusting when the FMacMenu adds and removes itself to the GCachedMenuState map.  This fix changes the access pattern to the map from operator[] (which uses a FindChecked underneath and is the cause of this crash/assert) to a FindRef then checking for a valid node.

	Since these crashes are at shutdown I think this is ok to do and I've tested with this fix in place, randomly not adding those items to GCachedMenuState object during editor operation and it now survives this and recovers if you then reenable the adding of the items.

	My best guess as to the cause is that the defered update event on shutdown is happenning way after the FMacMenu dealloc has been called and so the GCachedMenuState is empty by then.

	Speculative fix for crash in FMacWindow::ApplySizeAndModeChanges().  I had seen a crash in here while working on UE-46999 (fix for that submitted in CL 4016062) due to the window handle becoming nil mid way through the ApplySizeAndModeChanges() function then a deref'd.  This CL adds extra null pointer protection to make sure we check the validity of the WindowHandle after calls to UpdateFullScreenState().

	Clone of CL 4059587:  Fix for Sequencer window opening behind Main Window.  FLevelSequenceEditorToolkit::Initialize() Closes and reopens the world outliner after adding the Sequencer window.  On Mac this makes the world outliner / main window move back in front of the sequencer window.  This change swaps around those operations.  Reopen the world outliner then add the sequencer window.  Outliner info still changes it's visible data as before.

	Tested with World Outliner docked and undocked.

	Deleting keys, undoing the deletion, selecting them and then redoing the deletion no longer causes a crash in Sequencer/UMG's Curve Editors. KeyHandleLookupTables were not being serialized so when Undo/Redo transactions happened their map of the key handles would not be restored. This caused a mis-match in the data (the map contained more entries than actual data) so the map would falsely report a valid index when there was not one. Graph Editor selections are not sync'd with the Undo/Redo system currently so redoing a deletion after selecting keys would leave you in a state where you tried to request now out of bounds keys on the next Tick to update the UI.

Change 3851142 by Robert.Manuszewski

	When BP clustering is enabled, make sure to add the template to the BP cluster when replacing it.

Change 3853797 by Ben.Marsh

	BuildGraph: Add a <Trace> element, which allows logging messages after the string is parsed (as opposed to the Log task, which logs them at runtime). Useful for debugging macro expansion, etc...

	Also add a -showdiagnostics parameter, to have diagnostic messages output even when running with the -listonly option.

Change 3857540 by Graeme.Thornton

	Properly process the uexp file for a umap asset when generating a pak patch. Stop those uexp files being included in the patch even when they haven't changed

	See: https://udn.unrealengine.com/questions/412930/crash-due-to-default-constructor.html

Change 3864588 by Graeme.Thornton

	Crypto Keys Improvements
	 - Removed UAT command line params for encryption. Centrally configured by the editor settings now.
	 - UAT staging now creates a small json file containing the keys and settings used for encryption and signing and stores it in the build metadata
	 - Minor refactoring of UAT encryption processing to use the new cryptokeys json file
	 - UnrealPak can be told to get its encryption settings from a json crypto file with the "-CryptoKeys=<filename>"
	 - UnrealPak can now accept a "PatchCryptoKeys=<filename" parameter which gives it a filename to a cryptokeys json file that it can use to unpack the patch reference paks

Change 3864691 by Robert.Manuszewski

	Don't add objects that are in root set to GC clusters to prevent them from keeping the clusters alive forever.

	Algo::MinElement and Algo::MaxElement, for finding the minimum and maximum element in a range, and *By versions which take projections.
	TRangePointerType moved to its own file and used in Algo::MinElement and Algo::MaxElement.

Change 3874457 by Ben.Marsh

	When spawning child processes, only allow them to inherit the writable ends of the stderr and stdout pipe. Fixes an issue related to AutomationTool hanging when the editor closes after running automation tests.

	The editor launches ADB.EXE (Android Debug Bridge) on editor startup, which forks itself to initialize a server. Even though the child process has its own stdout and stderr pipes, it also inherits the pipes for the editor. When run from C#, as we do for automation tests, Process.WaitForExit() waits for all pipes to be closed before returning. This can't happen if the forked ADB instance still has a reference to the editor's pipes.

Change 3876435 by Robert.Manuszewski

	Don't add root set objects to level actor container to prevent situations where clusters are kept alive forever

Change 3878762 by Robert.Manuszewski

	Fixing potential LinkerLoad leak when a package that still has a linker associated with it is being destroyed.

Change 3878850 by Robert.Manuszewski

	SerializePreloadDependencies will now serialize raw data into the array instead of serializing one element at a time to speed up serialization performance.

Change 3881331 by Graeme.Thornton

	UGS: Change modal dialog to regular window style to avoid weird alignment issues under Windows 10.

Change 3887500 by Ben.Marsh

	UGS: Add support for grouping build badges by a prefix. Badges such as "Foo:Bar1", "Foo:Bar2" will be grouped together (with "Foo:" stripped from the displayed badge names).

	Also add a separate column showing the type of each change, rather than including it in the CIS column, and change badges to a more angular Windows 10 style.

Change 3887513 by Ben.Marsh

	UGS: Fix badge text drawing outside the clipping bounds.

Change 3889457 by Steve.Robb

	GitHub #4457 : Display abbreviations properly when converting FNames to display string

	#jira UE-54611

Change 3889547 by Ben.Marsh

	UGS: Add an extensible method for adding arbitrary badges to the right of the "description" column, by running a regular expression over the changelist description.

	Epic uses a "#tag" style annotations in changelist descriptions and Perforce triggers to verify them. "#jira" is used to link a changelist to an issue tracked in Jira, for example. A matcher to add a badge next to every changelist with a #jira tag, and link to the corresponding issue in Jira, could be set up with an addition to the project's Build/UnrealGameSync.ini file like this:

	[Badges]
	+DescriptionBadges=(Pattern="(?i)#\\s*jira\\s*:?\\s+([A-Za-z]+-[0-9]+)", Name="$1", Group="Jira", Color="#c0c0c0", HoverColor="#e0e0e0", Url="https://jira.it.epicgames.net/browse/$1")

	The "Pattern" attribute specifies the regex to match, and may capture portions of the matched text to be substituted later. "Label" specifies the label to appear on the badge. "Group" specifies an arbitrary identifier used to group related badges together rather than separating them with whitespace. "Color" and "HoverColor" specify hex RGB colors for the badges. "Url" specifies the path to open with a C# Process.Open call if the badge is clicked.

Change 3889726 by Ben.Marsh

	UGS: Fix description badges that don't have any associated URL.

Change 3889995 by Ben.Marsh

	UGS: Fix issue where popup menus can create top level windows in the taskbar. Seemlingly caused by capturing mouse before the window has been activated - removed capture code, and replaced with handling of OnMouseLeave() event instead.

Change 3890007 by Ben.Marsh

	UGS: Add a caption underneath the project logo which shows the current stream, to make it more obvious.

Change 3890057 by Ben.Marsh

	UGS: Fix repainting glitch when resizing window; bounds for status panel lines was not being reset correctly.

Change 3891069 by Robert.Manuszewski

	Fixing a crash in MallocBinned2 when running with malloc profiler enabled.

Change 3891084 by Steve.Robb

	Back out changelist 3881331 because it's causing cook errors.

Change 3891100 by Ben.Marsh

	UGS: Add support for a per-branch "message of the day"-style feature. Messages can be specified in a project's config file in Perforce (eg. <ProjectDir>/Build/UnrealGameSync.ini) as follows:

	[//UE4/Main/Samples/Games/ShooterGame.uproject]
	Message=:alert:  Lockdown for fixes is **5pm on Friday**. Only fixes for the 2.0 release should be submitted to this branch. [34 issues](https://jira.it.epicgames.net) are remaining as of 2/15.

	A limited subset of Markdown is supported: [web links](http://www.google.com), *italic*, _italic_, **bold**, __bold__. Icons will be supported through :icon: syntax; the only icon currently available is :alert:

Change 3895872 by Ben.Marsh

	UGS: Show the stream name in tab labels by default.

Change 3896366 by Ben.Marsh

	UGS: Automatically resize columns when the main window is resized, and allow specifying desired column widths for projects that have a large number of CIS badges.

	Columns are now resized proportionally, clamped to a minimum size. Columns will automatically expand up to a desired maximum size, though can be explicitly resized larger if necessary. Columns will not be resized if they are already larger than the window can show, or smaller than the window has space to show.

Change 3896367 by Ben.Marsh

	UGS: UI tweaks - change and time columns are now centered, "Unknown" badge is displayed until a change's type has been determined, increase height of status panel.

Change 3896425 by Ben.Marsh

	UGS: Speculative fix for race condition on clients displaying "under investigation" state. If the DB event is received before a change where an investigation is cancelled is polled from Perforce, we will exclude the resolve event from the list of active investigations.

Change 3896461 by Ben.Marsh

	UGS: Add an option to allow setting a tint color to be applied to the status panel, to allow identifying streams more easily. To use, add a setting similar to the following to a project's Build/UnrealGameSync.ini file:

	[//UE4/Main/Samples/Games/ShooterGame/ShooterGame.uproject]
	StatusPanelColor=#dcdcf0

Change 3899530 by Ben.Marsh

	Add unified syntax for overriding branch specific settings. Checks branch settings first, then [Default] section.

Change 3901164 by Ben.Marsh

	UGS: Add a class to store all the resources for the status panel.

Change 3901165 by Graeme.Thornton

	TBA: Attempt #2 at submitting the text asset saving code. SavePackage rejigged to write all header information in terms of FStructuredArchive, with all exports written through an FArchive adapter. Minimal amount of structured archive serialization functions added to allow this data to be written

Change 3901301 by Ben.Marsh

	UGS: Add support for reading the latest version of the project config file from Perforce. Some settings should be read depending on the CL you are synced to (eg. build steps), whereas others (MOTD, branch status) should always use the latest version. Will read the local version if checked out, to allow testing local changes.

Change 3902454 by Ben.Marsh

	UGS: Fix logo not being redrawn in the correct position when starting to sync.

Change 3903416 by Ben.Marsh

	UGS: Group badges explicitly through INI file rather than by expecting name to contain ':'.

Change 3904154 by Josh.Engebretson

	Adding Breakpad to ThirdParty sources (Git Commit: 49907e1c3457570f56d959ae26dec6c3a5edd417 https://chromium.googlesource.com/breakpad/breakpad)
	#jira UE-55442

Change 3904648 by Ben.Marsh

	UGS: Remove files from the workspace that are excluded by the sync filter.

	The user's config file stores a hash of the last sync filter. During syncing, if this hash doesn not match the previous value, we enumerate all the files in the #have list and remove anything masked out by the filter.

	#jira UE-47335

Change 3905442 by Steve.Robb

	Change of the ConvertFromType() multi-bool return value to a more descriptive enum.
	Some return values here do not make sense - this is because the existing logic is being preserved and will be fixed in a separate change.

Change 3905629 by Ben.Marsh

	UGS: Fix race condition between two child processes starting on different threads, and inheriting the other's intended stdout/stderr pipes. This prevents pipes being closed when one of the child processes shuts down, and causes waits on the read ends of those pipes to continue indefinitely.

Change 3906447 by Steve.Robb

	Rename EConvertFromTypeResult enumerators.

	Fix for GetLen(FString).

Change 3919610 by Ben.Marsh

	Put data for CrashReportClient in a PAK file of its own (under Engine/Programs/CrashReportClient/Content/Paks/CrashReportClient.pak). There are a large number of small files required for it to run with loose files, which takes a lot of space on disk (due to cluster sizes), and is unweildy to move around.

	CrashReporter UFS files are tracked in a separate dictionary to regular UFS files to allow construction of the additional PAK file.

Change 3921002 by Ben.Marsh

	UGS: Add option for syncing all projects in a branch. Off by default. Also add support for masking in additional paths to be synced (eg. one or two extra projects).

Change 3921008 by Ben.Marsh

	UGS: Prevent pause waiting for mutual exclusivity when syncing precompiled binaries. We don't need to generate project files or build, so there's no need to wait in line.

Change 3921906 by Steve.Robb

	New interpolation functions for quaternions.

Change 3921978 by Graeme.Thornton

	TBA: Make "Loader" member of FLinkerLoad private to prevent use outside of FLinkerLoad. This archive could be something unexpected if the linker is for a text asset package, so we need to stop people accessing it.

	UnrealPak: Improve encryption summary log messages

Change 3924522 by Graeme.Thornton

	UAT: Add *Encryption.ini to the list of auto-blacklisted config filenames

Change 3924604 by Graeme.Thornton

	UnrealPak: If encryption keys are parsed and fail the encrypt/decrypt test, throw a fatal error. The exectutable will have those same keys embedded so there is no point allowing the paks to be created with broken keys.

Change 3924638 by Graeme.Thornton

	Crypto: Improvements to parsing of old fashioned encryption.ini settings:
	 - AES keys that are too long or short (need to be 32 bytes) will now emit a warning when being parsed, and be truncated or expanded before adding to the crypto settings.
	 - Signing keys will emit an error when they are too long (>64bytes)
	 - Unrealpak will still assert when invalid settings are passed via the other mechanisms (command line or -encryptionini mode). Settings via the crypto json file should now be sanitized and not cause issues

	#jira UE-55080

Change 3924747 by Steve.Robb

	Fix for degrees.

Change 3925459 by Chad.Garyet

	Adding check to not to attempt to delete autosdk workspace if it doesn't already exist.

	BuildGraph: Include the path to the XML file when displaying an XML parse error.

Change 3926917 by Ben.Marsh

	UBT: Allow overriding the name of the UE4 solution on a branch-specific basis. Useful for switching between multiple UE4 workspaces. Also add support to the editor and UGS for opening the correct solution (determined via a text file saved to Engine/Intermediate/ProjectFiles).

	Set the solution name using an entry in BuildConfiguration.xml as follows:

		<ProjectFileGenerator>
			<MasterProjectName>UE4_Main</MasterProjectName>
		</ProjectFileGenerator>

Change 3927683 by Graeme.Thornton

	UAT: When building with chunk installs enabled, don't generate the master manifest from each pak creation thread. Just do it once after all pak files have been created. Avoids intermittent crash with multiple threads trying to write the same json file.

Change 3928111 by Ben.Marsh

	UBT: Add an option <bMasterProjectNameFromFolder> which allows setting the solution name based on the folder that it's in.

Change 3928926 by Ben.Marsh

	TBA: When loading assets, only use structured archive adapters for exports when loading text files.

Change 3936040 by Ben.Marsh

	UGS: Rewrite application lifecycle to fix issues with scheduled syncs on background windows not activating, and window jumping to the front after auto-update.

	Now uses a custom application context to allow creating separate 'main' windows (first the "opening projects" form, then the regular form), and does not require any forms to be shown in order to be updating in the background.

	UAT: CryptoKeys automation script

Change 3940321 by Ben.Marsh

	UGS: Add a "Bisect" mode for regressing bugs between a certain range of changes. To use, select a range of changes by holding down the shift key or individual changes by holidng the control key, then right click and select "Bisect these changes". Individual changes in the list can be marked as "Bisect: Pass" or "Bisect: Fail" from the context menu, and syncing will find the next change in the center of the range.

Change 3940538 by Ben.Marsh

	UBT: Always determine whether a project is a foreign project or not from the valid .uprojectdirs entries, rather than relying on the user passing -game on the command line.

	UE4 - Removed PRAGMA_DISABLE_OPTIMIZATION from PlatformFileCommon.h. It was an oversight.
	#jira none

Change 3942404 by Graeme.Thornton

	Pak Signing:
	 - Unify naming of pak precacher and signedarchivereader signature check functions to make it easier to search for them in crash reporter
	 - Format the signedarchivereader output to match the pak precacher
	 - When signedarchivereader detects a signature check, do the same master signature hash check that the pak precacher does to confirm that the .sig file contents haven't been corrupted since load.
	 - Add PAK_SIGNATURE_CHECK_FAILS_ARE_FATAL guarded exit to signedarchivereader signature failure
	 - Optimization for pakprecacher signature checks. Instead of locking the cached files mutex for every decoded signature, take a local copy in blocks of 16. Only re-lock if we need more. Grab the initial batch when setting up. In most cases, reduces the number of locks to 1 per signature check call.

Change 3942825 by Ben.Marsh

	UAT: Allow passing -Project<N>=Foo.uproject arguments to the MegaXGE commandlet (eg. -Target1="ShooterGame Win64 Development" -Project1="D:\ShooterGame\ShooterGame.uproject") so it can be used from an installed engine build.

Change 3942839 by Ben.Marsh

	UBT: Explicitly query the number of logical processors in the system, to fix Environment.ProcessorCount just returning the number available to the .NET framework. For machines with > 64 cores, processors in a different processor group will not be included in this number.

	PR #4558: Changed incorrect obsolete message for ReceiptPropertyList in Modules.cs (Contributed by ryanjon2040)


Change 3947359 by Graeme.Thornton

	TBA: Fixes to loading code to allow bulk data to get a pointer from its loader archive to an archive that it can load from at a later date. For binary archives, this is just a pointer back to the same archive, but for text assets it is a pointer to a "child reader" which maintains its own structured archive that is scoped to the current location in the file.

Change 3947360 by Graeme.Thornton

	TBA: Added RoundTrip mode to text asset commandlet. Performs determinism tests in project assets to see whether they save deterministically to binary and text files, and also when they are ping-ponged between the two formats.

Change 3949431 by Graeme.Thornton

	TBA: Refactored string escaping code in json output formatter FString serializer into a common function which is now used by FName and UObject path serialization too. Fixes some odd cases where an FName contained quotation marks

	Make RandInit(...) log message verbose

Change 3954694 by Ben.Marsh

	BuildGraph: Add support for user-defined macros, which can contain a list of buildgraph commands and be expanded within a node. Example script in Engine/Build/Graph/Examples/Macros.xml.

	To define a Macro, use the syntax:

		<Macro Name="MyTestMacro" Arguments="PrintFirstMessage;PrintSecondMessage" OptionalArguments="PrintThirdMessage">
			<Log Message="First message" If="$(PrintFirstMessage)"/>
			<Log Message="Second message" If="$(PrintSecondMessage)"/>
			<Log Message="Third message" If="'$(PrintThirdMessage)' == 'true'"/>
		</Macro>

	To expand a macro, use the syntax:

		<Expand Name="MyTestMacro" PrintFirstMessage="true" PrintSecondMessage="true"/>

	An error will be thrown if any required arguments are missing. Optional arguments default to empty if not specified.

	Tasks within a macro are validated by the schema at the point of definition using the same rules as apply to a <Node> element, but properties are not evaluated until the macro is expanded. This allows macros to get and set properties in scope at the point that it is expanded. Local properties that are introduced within a macro do not otherwise leak to the scope that they are expanded.

	TBA: Text asset loading/saving work
	 - Start using FStructuredArchive flavours of UObject Serialize functions when loading and saving exports.
	 - Only use FStructuredArchive interface for text assets, and for classes that have the CLASS_MatchingSerializers which tells us that the class can serialize to both FStructuredArchives and FArchives.
	 - Add GetCacheableArchive to FArchive, which allows transient archives to return a pointer to another archive that will outlive it. Used by bulk data to get a pointer to an archive that can be held and used at a later time to lazy load things. For text assets where the bulk data might be held inside a base64 encoded FArchiveFromStructuredArchive block, we can't dynamically seek back to that location after the on-stack wrapper has been destroyed after the original serialize, so this will return null. For binary assets, we just return a pointer to the same binary archive which can be used freely.

Change 3990823 by Ben.Marsh

	UGS: Allow project settings to specify a client path rather than a filesystem path. Not currently usable through UI.

Change 3990832 by Ben.Marsh

	UGS: Make the schedule window resizable.

Change 3991569 by Steve.Robb

	GitHub #4636 : Fixed typo in HeaderParser.cpp for "missed WithValidation keyword" error message

Change 3991970 by Steve.Robb

	Fix for 4096 char limit on FParse::Value.

Change 3992222 by Steve.Robb

	Advice added to the coding standard for using default member initializers.

Change 3993675 by Ben.Marsh

	UGS: Add UI to allow creating new workspaces and selecting projects from existing workspaces that are not currently synced.

Change 3994199 by Ben.Marsh

	UGS: Fix child processes being unable to spawn other child processes with the CREATE_BREAKAWAY_FROM_JOB flag, to add them to their own job objects.

	In Windows 7 or earlier job objects cannot be nested, so child processes have to create separate job objects and spawn processes with CREATE_BREAKAWAY_FROM_JOB to be able to add them. This fails unless parent process' job object was created with JOB_OBJECT_LIMIT_BREAKAWAY_OK.

	Discussed here: https://msdn.microsoft.com/en-us/library/windows/desktop/hh448388(v=vs.85).aspx

Change 3994243 by Ben.Marsh

	UGS: Use the select stream dialog instead of displaying a drop list unless there's a stream filter specified. We have way too many streams for this to be useful in a menu unless it's filtered.

Change 3994260 by Ben.Marsh

	UGS: Tweak the stream filter dialog to only use the previous selected node if the filter terms match. It may be a parent node of something that matches, even though it doesn't match itself.

Change 3994350 by Ben.Marsh

	UGS: Automatically guess the correct root path for new workspaces based on the most common existing workspaces for the current user.

Change 3995159 by Ben.Marsh

	UGS: Do not delete files which are outside the sync filter. People expect to be able to sync different projects within a stream without having to update sync filters.

	Indend to re-introduce this functionality through the manual 'clean workspace' operation.

Change 3995169 by Ben.Marsh

	UGS: Show options as dimmed in the open project dialog, if the radio button for those controls is not checked. Automatically set the radio button if the focus is given to one of those controls.

Change 3995228 by Ben.Marsh

	UGS: Update recently opened projects list when editing project for an existing tab.

Change 3995312 by Ben.Marsh

	UGS: Stop showing all dialogs in the taskbar.

Change 3995929 by Robert.Manuszewski

	Completely rewritten FReferenceChainSearch class used by 'obj refs' command.

	- 3+ times faster
	- Uses the same code as GC to track all the references down
	- Actually reports all reference chains properly
	- Less code that is more readable than the previous version

Change 3995981 by Ben.Marsh

	UGS: Clean workspace window will now force-sync files that have been deleted or which are writable.

Change 3996113 by Ben.Marsh

	UGS: Fix crash upgrading config files from older versions.

Change 3997990 by Ben.Marsh

	UGS: Prevent error when syncing an empty workspace.

Change 3998095 by Ben.Marsh

	UGS: Change logic for dealing with job objects: rather than creating breakaway jobs (requires co-operation with spawning process), always try to use nested job objects (requires Windows 8.1+). If it fails, ignore the error if we're already part of a job.

	Also forcibly terminate the process on dispose to handle cases where the job object wasn't created.

Change 3998264 by Ben.Marsh

	UGS: Fix exception when switching projects in-place.

Change 3998643 by Ben.Marsh

	Fix shared DDC not being used for installed engine builds.

	#jira UE-57631

Change 4000266 by Ben.Marsh

	UnrealPak: Add an option that allows rebuilding a set of PAK files with different settings. Usage is:

	    UnrealPak [PakFile] -Repack [-Output=FileOrDirectory] [Options]

	The input pak file may be a single file or wildcard, and is overwritten unless the -Output parameter is specified.

Change 4000293 by Ben.Marsh

	Add a compression flag that allows selecting compressor without using the default platform implementation.

Change 4000315 by Ben.Marsh

	Add support for custom compressors implemented via modular features. Specify -compressor=<PathToDll> on the command line to UnrealPak to load a compressor from an external DLL.

Change 4000610 by Ben.Marsh

	UnrealPak: Add a parameter for compression block size (-compressionblocksize=XXX). Accepts arguments with MB/KB suffixes, as well as byte counts.

Change 4000627 by Ben.Marsh

	UBT: Include enabled plugin info in the UBT log.

Change 4000793 by Ben.Marsh

	UBT: Remove some member variables from VCEnvironment that don't need to be stored.

Change 4000909 by Ben.Marsh

	UBT: Add VS2017 installations to the list of paths checked for MSBuild installations.

Change 4001923 by Ben.Marsh

	UBT: Allow any plugins which are enabled by default to be included in the enabled list, even if they don't have any modules for the current platform. This changes the build-time logic to match the runtime logic.

	At some point in the future we may add a separate SupportedHostPlatforms list to each plugin to do this explicitly, rather than guessing via the per-module whitelist.

Change 4001927 by Ben.Marsh

	Fixes for compiling against the Windows 10 SDK.

Change 4002439 by Robert.Manuszewski

	Added TDefaultReferenceCollector and FSimpleReferenceProcessorBase to extract common code for clients of  TFastReferenceCollector

	UGS: Update version number.

Change 4005112 by Ben.Marsh

	UBT: Reduce number of times a target has to be constructed while generating project files.

Change 4005513 by Ben.Marsh

Change 4005516 by Ben.Marsh

	UBT: Add warnings whenever a module adds an include path or library path that doesn't exist

Change 4006168 by Ben.Marsh

	CIS fixes.

Change 4006236 by Ben.Marsh

	UGS: Populate the workspace name/root directory text box with the cue banner when focus moves to the control.

Change 4006266 by Ben.Marsh

	UGS: Swap around the new workspace/existing file boxes on the open project dialog.

Change 4006552 by Ben.Marsh

Change 4007397 by Steve.Robb

	Comments added to make it clear that GetAllocatedSize() only counts direct allocations made by the container.

Change 4007458 by Ben.Marsh

	UBT: Change RPC utility to abort early, rather than continue to try to build even though SSH init failed.

Change 4009343 by Ben.Marsh

	UGS: Set the rmdir option on new workspaces by default.

Change 4009501 by Ben.Marsh

	UBT: Add Windows include paths to the compiler command line, rather than setting through environment variables. This ensures that incremental builds work correctly when SDK versions change.

Change 4009509 by Ben.Marsh

	UBT: Check in a non-versioned directory under the Windows 10 SDK for the resource compiler.

Change 4010543 by Ben.Marsh

	Remove the "Device" and "Simulator" platform groups, because they're unused and overly generic for folder names. Also remove source code for the HTML5 simulator (which is no longer supported).

Change 4010553 by Ben.Marsh

	UAT: Include platform groups in restricted folder names when staging.

Change 4012030 by Ben.Marsh

	UGS: Increase the size of the main window, and set the current stream as the default when creating a new workspace.

Change 4012204 by Chad.Garyet

	- Cleanup to get the POSTs returning 400s the same way the GETs would (now no longer returns the exception text)
	- Create directory for sqlite db if it doesn't exist
	#jira none

Change 4014209 by Brandon.Schaefer

	New changes in breakpad dump_syms to allow for producing a symbol file for elf files on windows

	#review-3998840 @Arciel.Rekman, @Ben.Marsh, @Josh.Engebreston, @Anthony.Bills

Change 4015606 by Brandon.Schaefer

	Missed a code project that needed updating for new Breakpad changes for Mac

Change 4017795 by Robert.Manuszewski

	Update message about downloading a new version of Visual Studio.

Change 4022063 by Ben.Marsh

	UBT: Suppress toolchain output when generating project files.

Change 4023248 by Ben.Marsh

	Install an unhandled exception filter to ensure we get crash reports from threads that are not spawned by the engine. At the moment, we only receive crashes that are routed through ReportCrash() via our structured exception handlers in WinMain() and FRunnableThreadWin::Run().

	(Also fix an exception within the exception handler, if GError has not been created yet)

Change 4025759 by Ben.Marsh

	Fix universal CRT include paths not being added to compile environment for VS2015.

Change 4026002 by Ben.Marsh

	UBT: Check the old registry locations for the Windows SDK installation directory.

Change 4026068 by Ben.Marsh

	UBT: Use the correct compiler version in the error message for not having the UCRT.

Change 4026181 by Ben.Marsh

	Fix DebugGame editor configurations not enumerating modules correctly.

	#jira UE-58153

	UBT: Add additional logging for enumerating Windows SDKs.

Change 4026708 by Ben.Marsh

	UBT: Keep a separate list of installed Universal CRT versions to the list of Windows 10 SDK versions. It's possible to install C++ support without the Windows 10 SDK, which still includes UCRT files in Windows 10 SDK folders.

Change 4029404 by Ben.Marsh

	Remove incorrect include paths to fix CIS warnings.

Change 4031517 by Steve.Robb

	Fix for UHT errors not being clickable in the Message Log.

Change 4032262 by Ben.Marsh

	BuildGraph: Remove the need to copy files to the staging directory in BuildEditorAndTools.xml.

Change 4032288 by Ben.Marsh

	Remove UFE from the BuildEditorAndTools script.

Change 3833533 by Ben.Marsh

	Rewrite engine source files to base include paths relative to the "Public" directory. This allows reducing the number of public include paths that have to be added for engine modules.

Change 3838569 by Steve.Robb

	Algo moved up a folder.

Change 3848581 by Robert.Manuszewski

	Changing the UObjectArray to not be allocated up front but in 64K-FUObjectItem chunks. This is to fix strange OOM reports on editor startup where it's trying to allocate space for 1M+ FUObjectItems.

	#jira UE-49446

Change 3864743 by Steve.Robb

	Fix for buffer overrun when copying a context string.
	Fix for being unable to link to MallocLeakDetection.
	Fix to prefix for FMallocLeakDetection::ContextString.
	New MALLOCLEAK_SCOPED_CONTEXT macro to push/pop a context string.
	Overload for const TCHAR* added to FMallocLeakDetection::PushContext to save on redundant memory allocations.

	#jira UE-54612

Change 3865020 by Graeme.Thornton

	TBA: Changed FIELD_NAME macro to FIELD_NAME_TEXT so that FIELD_NAME can be used for non-literal name definitions

Change 3869550 by Josh.Engebretson

	New SymGen and SymUpload tasks (ShooterGame usage example)
	Example C# symbolicator (using saved crash and data router formats)

Change 3910012 by Ben.Marsh

	UGS: Show an error window and allow setting default P4 server settings if syncing UGS fails.

Change 3920044 by Graeme.Thornton

	TBA: Text asset loading

	* Added a structured archive layer to FLinkerLoad
	* Wrapped export loading in a ArchiveUObjectFromStructuredArchive
	* Updated TextAssetCommandlet to have a "loadtext" mode which will try to load every text asset in the project content
	* Changed text asset extensions to .utextasset and .utextmap. Couldn't go with the favourite .uasset.json because our various path functions (FPaths::GetCleanFilename etc.) will only strip one layer of extension, so leave a bogus filename.
	* Relaxed a few checks in structured archive where it was checking for field reentrance, which isn't a problem for loading.
	* Changed FArchiveFromStructuredArchive to not load all referenced objects at construction time. This introduced some changes to load order which don't work in the engine. Object names are resolved at the point that a reference to them is serialized from the main data block, same as with legacy archives.

Change 3921587 by Steve.Robb

	Static asserts inside ensureMsgf() macros to prevent them being passed invalid arguments or non-literal formatting strings.
	Fixes for various misuses.

	#jira UE-55681

Change 3942873 by Ben.Marsh

	UBT: Allow link time code generation on any configurations where bAllowLTCG is set to true. Microsoft platforms were previously only allowing this option in shipping; the target can decide when to enable it or not.

Change 3944629 by Graeme.Thornton

	Merging back a couple of fixes from Fortnite
	 - Extra parenthesis around some calculations in the pakprecacher
	 - Changed FChunkCacheWorker::DoSignatureCheck() back to ::CheckSignature()
	 - Added documentation for build script crypto options

Change 3945381 by Ben.Marsh

	Disable warning C4770 on Windows (partially validated enum 'xxx' used as index), which occurs when enabling LTCG. Can't find a reference online for this warning, but I suspect it's due to LTCG allowing the compiler to trace code paths where we don't validate that an enum is a known value.

Change 3968969 by Steve.Robb

	Fixes to incorrect uses of FScriptMapHelper and FScriptSetHelper, which weren't accounting for gaps in the sparse array.

Change 3969417 by Ben.Marsh

	Make Visual Studio 2017 the default compiler for UE4 projects, and add support using Visual C++ toolchains from an AutoSDKs.

	Also add support for selecting a specific toolchain version to use through the WindowsPlatform.CompilerVersion property, which can be configured via a Target.cs files or BuildConfiguration.xml (eg. <WindowsPlatform><CompilerVersion>14.13.26128</CompilerVersion></WindowsPlatform). As well as allowing a specific version number, you can always use the latest toolchain by setting it to "Latest".

Change 3972443 by Ben.Marsh

	Change build scripts to allow running any steps on non-compile workspaces. Setup Dev-Core to just use a non-compile Win64 workspace for everything.

Change 3977198 by Ben.Marsh

	Remove INI file override for editor stack size on Windows. This is rarely valid since editor targets share build products with other games by deafult. Fix to add linker response file as prerequisite exposed targets overriding this as a bug.

Change 3979632 by Ben.Marsh

	Consolidate codepaths for embedding versioning information in the engine. Engine/Build/Build.version is now the authoritative place to read version information; Engine/Source/Runtime/Launch/Resources/Version.h no longer includes macros for the current branch and changelist.

	* Settings from Build.version are compiled into the (tiny) BuildSettings module via macros set in BuildSettings.build.cs, which is used to initialize version information inside the engine at runtime.
	* The IsPromotedBuild value is now set to zero by default (but set to 1 by the UpdateLocalVersion UAT command).
	* The -Licensee argument to the UpdateLocalVersion UAT command, and the IsLicenseeVersion setting for UnrealGameSync, is determined automatically by looking for the Engine/Build/NotForLicensees/EpicInternal.txt file. This path is not visible to licensees.

Change 3981738 by Ben.Marsh

	Move utility classes for filtering files and matching wildcards into DotNETUtilities.

Change 3983888 by Steve.Robb

	Warning C4868 disabled, about evaluation order of braced initializer lists.

	https://udn.unrealengine.com/questions/426081/help-with-error-c4868-braced-initializers.html

Change 3984019 by Steve.Robb

	FString::Printf formatting argument checking added.
	Vararg support for FText::Format.
	All remaining usage fixed.

Change 3985502 by Steve.Robb

	Change to TFunction debugger visualization to allow right-clicking on the [Lambda] and selecting 'Go To Source Code'.

Change 3985999 by Graeme.Thornton

	TBA: Serialize function generation for FArchive and FStructuredArchive overloads on a UObject, using UHT.
	 - Adds a restriction that UObject::Serialize() functions MUST be declared outside of any conditional compilation directives, except for WITH_EDITORONLY_DATA

Change 3986461 by Ben.Marsh

	Fixup lots of platforms not adding response files as a prerequisite.

	This can cause incremental builds to fail if input files/compile arguments change, because the action graph does not know that the response file being updated invalidates the build artifacts.

Change 3990081 by Ben.Marsh

	Remove custom output formatters for errors and warnings. These are not well supported by different executors, and cause fences between actions with the same formatter with external executors like XGE.

	Clang supports -fdiagnostics-format=msvc for all platforms, which should do a better job than our crude attempts at regexing errors (causing botched output in some cases).

Change 3996714 by Chad.Garyet

	UGSRestAPI, conversion of UGS to use it.

	#jira none

Change 4008287 by Ben.Marsh

	UBT: Change the engine to use the Windows 10 SDK by default.

	Also add support for switching between specific Windows SDK versions. The WindowsPlatform.WindowsSdkVersion property in the target rules can be used to select a desired version, which can also be configured by the <WindowsPlatform><WindowsSdkVersion>Foo</WindowsSdkVersion></WindowsPlatform> parameter in the BuildConfiguration.xml file.

	The version of Windows to target (ie. the WINVER macro) can be modified by setting WindowsPlatform.TargetWindowsVersion. The default is 0x0601 (Windows 7).

Change 4008516 by Chad.Garyet

	- Adding support for both SQLite and MsSql
	- API now reads from only MsSql, but writes to both
	- Added support for POST to CIS for badges
	- PostBadgeStatus now writes out via API Url rather than a direct connection to the DB

	#jira none

Change 4010296 by Chad.Garyet

	Moving SQLite db initilization into Application_Start.  An exception thrown creating or seeding the db will unload the entire AppDomain and all pages will return a 404.
	#jira none

Change 4024045 by Ben.Marsh

	Set the list of supported target platforms for OnlineSubsystemGameCircle.

	#jira UE-57887

Change 4031014 by Ben.Marsh

	UAT: Add a WhitelistDirectories list in DefaultEngine.ini, which allows specifying folders that can be staged despite having restricted folder names.

Change 3650300 by Ben.Marsh

	UAT: Remove code that deletes cooked data on a failed cook. The engine should write packages out transactionally now (by writing to a temporary file and moving into place), and deleting the cooked data just prevents post-mortem analysis.

Change 3770826 by Ben.Marsh

	Move StructuredArchive implementation into Core, so primitive types can implement serialization overloads for it.

Change 3770875 by Steve.Robb

	Redundant UScriptStruct::PostLoad removed, which was causing a race condition in async loading.  This was re-establishing the CppStructOps, but that is unnecessary because native classes cannot change as a result of a load - only BP structs can, and they don't have CppStructOps.

Change 3772955 by Ben.Marsh

	Add a new "stream" compound type to FStructuredArchive, which allows serializing a sequence of elements similarly to an array, but without serializing an explicit size. Allows passing through data to an underlying binary archive without breaking compatibility.

Change 3772963 by Ben.Marsh

	Allow querying record keys and stream lengths from annotated archive formatters, since these archives have markup for field boundaries.

Change 3773010 by Graeme.Thornton

Change 3773057 by Ben.Marsh

	Add a flag to FArchive to determine whether the archive is text (IsTextFormat()).

	Add support for seeking within FArchiveFromStructuredArchive. For text formats, data is serialized to an in-memory buffer, with names and objects serialized as indices into an array. For non-text formats, data is serialized directly to the underlying archive.

	TBA: Optimize creation of stack elements for empty slots in FStructuredArchive. This saves a lot of bookkeeping when serializing a large number of individual fields.

	Fixes to everything which didn't compile as a result.

Change 3650813 by Graeme.Thornton

	Removed FStartupPackages and associated code

Change 3651000 by Ben.Marsh

	Return the stack size from FPlatformStackWalk::CaptureStackBacktrace() rather than checking for the first null pointer, to prevent truncated callstacks if parts of the stack are zeroed out.

	#jira UE-49980

Change 3690842 by Steve.Robb

	FPlatformAtomics::AtomicRead added - needs optimizing.
	AtomicRead() used in FThreadSafeCounter::GetValue().

Change 3699416 by Steve.Robb

	Fix to debugger visualization of TArray with a TInlineAllocator or TFixedAllocator.
	Improved readability of TSparseArray visualization.

Change 3720812 by Steve.Robb

	Atomic functions for 8-bit and 16-bit.
	Android, Linux and Switch implementations now just use the Clang implementation.
	AtomicRead64 deprecated in favor of the int64* AtomicRead overload.

Change 3722698 by Steve.Robb

	VS debugger visualizers for TAtomic.

Change 3732270 by Steve.Robb

	#jira UE-52034

Change 3750657 by Josh.Engebretson

	Fixed issue when debugging editor cook/package and project launch operations

	#jira UE-52207

Change 3758514 by Steve.Robb

	Fixes to FString::Printf having non-literals being passed as its formatting string.

Change 3763356 by Steve.Robb

	ENamedThreads::RenderThread and ENamedThreads::RenderThread_Local encapsulated by getters and setters.

Change 3770549 by Steve.Robb

	Removal of obsolete PLATFORM_COMPILER_HAS_DEFAULTED_FUNCTIONS and PLATFORM_COMPILER_HAS_AUTO_RETURN_TYPES.
	Tidy up of existing code which uses it.

Change 3770553 by Ben.Marsh

	Adding structured serialization API to Core/CoreUObject for use with text-based assets.

	* FStructuredArchive abstracts an archive which is made up of compound types (records, arrays, and maps). Values are stored in slots within these types.
	* Records are string -> value dictionaries where the key names can be compiled out in non-editor builds or when WITH_TEXT_ARCHIVE_SUPPORT = 0.
	* Maps are string -> value dictionaries where the key names are present regardless of the build type.
	* Proxy objects are defined to express the context for serialization (FStructuredArchive::FRecord, FStructuredArchive::FArray, FStructuredArchive::FMap, FStructuredArchive::FSlot) which allows basic validation through static typing. These objects act as lightweight handles, and can be cheaply constructed and passed around on the stack. Most serialization to and from the archive is done through these objects.
	* Runtime checks perform additional validation to ensure that serialized data is well formed and written in a forward-only manner, regardless of the underlying archive type.
	* The actual input/output format is determined by a separate interface (FArchiveFormatter). Context validation (always causing matching LeaveArray for every EnterArray, etc...) is done by FStructuredArchive, so implementing these classes is fairly trivial. FArchiveFormatter can be de-virtualized in non-editor builds, where WITH_TEXT_ARCHIVE_SUPPORT = 0.
	* Includes implementations of FArchiveFormatter for binary and JSON formats.

Change 3771105 by Steve.Robb

	Deprecation warnings for PLATFORM_COMPILER_HAS_AUTO_RETURN_TYPES and PLATFORM_COMPILER_HAS_DEFAULTED_FUNCTIONS.
	Fix for incorrect warning formatting on Clang platforms.

Change 3771520 by Steve.Robb

	Start moving Clang-using platforms' pre-setup stuff into a Clang-specific header.

Change 3771564 by Steve.Robb

	More common macros moved to the Clang pre-setup header.

Change 3771613 by Steve.Robb

	EMIT_CUSTOM_WARNING_AT_LINE moved to ClangPlatformCompilerPreSetup.h.

Change 3772881 by Ben.Marsh

	Add support for serializing FName and UObject through FStructuredArchive.

	In order to allow custom linker behavior when serializing objects:

	* The constructor to JSON input formatter now takes a delegate to convert a string object name into a UObject pointer.
	* The constructor to tagged binary formatter takes a delegate to serialize a UObject pointer into any form it chooses (likely an integer index into the import table)

	Object and name types are stored as strings in JSON, using an "Object:" or "Name:" prefix to differentiate them from regular strings. Any strings that already contain one of these prefixes are prepended with a "String:" prefix (as is any string that already has a "String:" prefix).

Change 3772941 by Graeme.Thornton

	Make build work when including StructuredArchive.h from core container types
	Added standard header to new files
	Add structured archive serializer for TArray
	Fix bug in structured archive where containers weren't being popped from the scope stack

Change 3772972 by Ben.Marsh

	Add an adapter which presents a legacy FArchive interface to a FStructuredArchive slot.

	Data is serialized into this slot as a stream of elements; raw data is buffered up into fixed size chunks, names and objects are serialized separately.

	When used with FBinaryArchiveFormatter, this should result in all data being passed through to the underlying archive in a backwards compatible way, wiith no additional bookkeeping fields.

Change 3773006 by Ben.Marsh

	Rename FStructuredArchive::FRecord::EnterSlot() to EnterField().

Change 3773013 by Steve.Robb

	bUseInlining target rule added to UnrealBuildTool, which defaults to true, to allow inlining to be disabled for debugging purposes.

Change 3774499 by Ben.Marsh

	Minor fixes for FStructuredArchive related classes:

	* Text-based archive formats are now compiled out when WITH_TEXT_ARCHIVE_SUPPORT = 0.
	* Fixed issue with FTaggedBinaryArchiveFormatter state becoming corrupted when looking ahead at field types.
	* FArchiveFieldName constructor is now explicit, to fix cases where strings were being passed directly to serialize functions.

Change 3774600 by Ben.Marsh

	Add CopyFormattedData() function, which can copy data from one formatter to another. Add a test case to SerializationAPI that converts from data -> JSON -> binary -> JSON -> data.

	This function can be used to implement a generic visitor pattern, by implementing a FArchiveFormatter which receives the deserialized data.

Change 3789721 by Ben.Marsh

	TBA: Split FTaggedBinaryArchiveFormatter into separate classes for reading and writing.

Change 3789920 by Ben.Marsh

	TBA: Support automatic coercion between any numeric types in tagged binary archives. Also report the smallest type that can contain a value, rather than just in32/double.

	#jira UECORE-364

Change 3789982 by Ben.Marsh

	TBA: Change FStructuredArchive::Open() to return a slot, rather than a record, to make it easier to implement a raw FArchive adapter.

Change 3792466 by Ben.Marsh

	TBA: Better handling of raw data in text based assets. Short sequences of binary data are Base64 encoded as a single string. Longer sequences are stored as an array of Base64 encoded lines, push a SHA1 hash to detect cases where the data was merged incorrectly.

	In order to allow inference of the correct type for a field, other fields called "Base64" will be escaped to "_Base64", and any field beginning with "_" will have an additional underscore inserted. Reading files back in reverses these transformations.

Change 3792935 by Ben.Marsh

	TBA: Rename FArchiveFormatter to FStructuredArchiveFormatter for consistency with FStructuredArchive.

Change 3795100 by Ben.Marsh

	UBT: Rename the ModuleRules Definitions property to PublicDefinitions, to make its semantics clearer.

Change 3795106 by Ben.Marsh

	Replace all internal usages of ModuleRules.Definitions, and replace it with ModuleRules.PublicDefinitions.

Change 3796275 by Ben.Marsh

	Fix paths to Version.h includes from resource files.

Change 3800683 by Josh.Engebretson

	Remove WER from Mac and Linux crash reports in favor of unified runtime-xml format
	#jira UE-50073

Change 3803545 by Steve.Robb

	TWeakObjPtr const-dropping assignment fix.
	Fixes to change.

Change 3498112 by Ben.Marsh

	UBT: Respect the option to not create debug info in the Android toolchain. This option is already being respected by the compiler, but the linker adds debug info of its own.

Change 3500239 by Robert.Manuszewski

	Made sure the Super Class token stream is also locked when assembling Class token stream with async loading thread enabled. This to to prevent race conditions when loading BP classes.

Change 3500395 by Steve.Robb

	Extra codegen savings when not in hot reload.

Change 3501004 by Steve.Robb

	EObjectFlags now have constexpr operators.

Change 3502079 by Ben.Marsh

Change 3504712 by Ben.Marsh

	UAT: Less spammy log and error output from UAT.

	* Callstacks for AutomationExceptions are suppressed by default but still included in the log (the path to the log is noted in console output with the message from the exception).
	* Add a mechanism for any exceptions to be caught and rethrown with additional lines of context (CommandUtils.AddContext()) that will be appended to the error output by UAT. Avoids decaying the exception type or masking the inner exception message while still adding additional information.
	* AggregateExceptions resulting from exceptions on child threads are automatically unwrapped (full details are still appended to the log)
	* Name of the calling function is not included in console output by default, but still included in the log.

Change 3504808 by Ben.Marsh

	UAT: Suppress P4 output when running a recursive instance of UAT.

Change 3505044 by Steve.Robb

	Fix deterministic cooking issue; always use a pseudo-random number stream when compiling a module.

Change 3505699 by Ben.Marsh

	Plugins: Store the bEnabledByDefault flag exactly as it was read from disk rather than collapsing it to an absolute value based on the default for the location it was read from. This allows loading/saving plugin descriptors without any knowledge of whether they are game or engine plugins.

Change 3506055 by Ben.Marsh

	UAT: Add a class to apply a log indent for the lifetime of an object (ScopedLogIndent), and use it to apply an indent to MegaXGE/ParallelExecutor output.

Change 3507745 by Robert.Manuszewski

	Moved FSimpleObjectReferenceCollectorArchive and FSimpleObjectReferenceCollectorArchive to be internal archives used only by FReferenceCollector so that they are constructed only once per GC task instead of potentially multiple times per GC (as was the case with UDataTables and BlueprintGeneratedClasses).

Change 3507911 by Ben.Marsh

	Plugins: Minor changes to plugin descriptors.

	* Add a distinct setting for an unspecified EnabledByDefault setting in plugin descriptors.
	* Add a function to IPlugin to determine the effective EnabledByDefault setting, based on where the plugin was loaded from.

	Custom Version Container will no longer be always constructed in FArchive constructor. This reduces the number of the Custom Version Container allocations considerably.

Change 3509294 by Robert.Manuszewski

	UDataTable::AddReferencedObjects will no longer try to iterate over the RowMap if there's no UObject references in it.

Change 3509312 by Steve.Robb

	UE4 - Fix rare assert involving cancelled precache requests and non-pak-file loading.

Change 3510593 by Daniel.Lamb

	Fixed up unsoilicited files getting populated with files which aren't finished being created yet.

	#test None

Change 3510594 by Daniel.Lamb

	Fixed up temp files directory for patching.

	Thanks David Yerkess @ Milestone
	#review@Ben.Marsh

	PR #3707: Fixed UBT stack size (Contributed by gildor2)


Change 3511808 by Ben.Marsh

	Optimize checks for whether the game project contains source code. Now stops as soon as the first file is found and ignores directories beginning with a '.' character (eg. .git)

	#jira UE-46540

Change 3512017 by Ben.Marsh

	Plugins: Deprecate the QueryStatusForAllPlugins() function; the same functionality is available via the IPlugin interface.

Change 3513935 by Steve.Robb

	Reverted array iteration in FPropertyNode::PropagatePropertyChange as this is now covered in TProperty::InitializeValueInternal() as of CL# 3293477.

Change 3514142 by Steve.Robb

	MemoryProfiler2 added to generated solution.

Change 3516463 by Ben.Marsh

	Plugins: Create a manifest for each PAK file containing all the plugin descriptors in one place. Eliminates need to recurse through directories and read separate multiple files in serial at startup, and allows reading all plugin descriptors with one read. The "Mods" directory is excluded from the manifest, since these are intended to be installed separately by the user.

Change 3517860 by Ben.Marsh

	PR #3727: FString Dereference Fixes (Contributed by jovisgCL)


Change 3517967 by Ben.Marsh

	Suppress additional system error dialogs when loading DLLs if -unnattended is on the command line.

Change 3518070 by Steve.Robb

	Disable Binned2 stats in shipping non-editor builds.

	Force a GC after hot reload to clean up reinstanced objects which may still tick.

	#jira UE-40421

Change 3520480 by Robert.Manuszewski

	Improved assert message when the initial package read request was too small.

Change 3520590 by Graeme.Thornton

	SignedArchiveReader optimizations
	 - Loads more stats
	 - Stop chunk cache worker from waking up continuously to poll for work. Only wake up when triggered by the archive reader
	 - Signed archive reader just yields when waiting for buffers to finish loading, rather than sleeping for some arbitrary amount of time
	 - Track the number of pending read requests in an atomic counter, to save having to lock the request queue to check for new entries

Change 3521023 by Graeme.Thornton

	Remove spin from signed archive reader. Main thread waits on an event triggered by the chunk worker to indicate that new chunks are ready for processing

Change 3521787 by Ben.Marsh

	PR #3736: Small static code analysis fixes (Contributed by jovisgCL)


Change 3521789 by Ben.Marsh

	PR #3735: Fix case sensitivity issue in FWindowsPlatformProcess::IsApplicationRunning. (Contributed by samhocevar)


Change 3524721 by Ben.Marsh

	Move Linux SDL initialization into FLinuxPlatformApplicationMisc. Attempting to move functionality related to interactive applications (graphics, input, etc...) into a separate place, so it can ultimately be moved out of Core.

Change 3524741 by Ben.Marsh

	Move PumpMessages() into FPlatformApplicationMisc.

Change 3525399 by Ben.Marsh

	UGS: Use the default Perforce server port when opening P4V if there is not one set in the environment.

Change 3525743 by Ben.Marsh

	UAT: Add a parameter to allow updating version files without updating Version.h, to allow faster link times on incremental builds.

Change 3525746 by Ben.Marsh

	EC: Include the clobber option on new workspaces, to allow overriding version files when syncing.

Change 3526453 by Ben.Marsh

	UGS: Do not generate project files when syncing precompiled binaries.

Change 3527045 by Ben.Marsh

	Fix hot reload generating import libraries without DLLs. Now that they are produced by separate actions by default, it was removing DLLs from the action graph due to the bSkipLinkingWhenNothingToCompile setting.

Change 3527420 by Ben.Marsh

	UGS: Add additional search paths for UGS config files, and fix a few cosmetic issues (inability to display ampersands in tools menu, showing changelist -1 when running a tool without syncing).

	Config files are now read from:

	Engine/Programs/UnrealGameSync/UnrealGameSync.ini
	Engine/Programs/UnrealGameSync/NotForLicensees/UnrealGameSync.ini

	If a project is selected:

	<ProjectDir>/Build/UnrealGameSync.ini
	<ProjectDir>/Build/NotForLicensees/UnrealGameSync.ini

	If the .uprojectdirs file is selected:

	Engine/Programs/UnrealGameSync/DefaultProject.ini
	Engine/Programs/UnrealGameSync/NotForLicensees/DefaultProject.ini

Change 3528063 by Ben.Marsh

	Fix non-thread safe construction of FPluginManager singleton. Length of time spent in the constructor resulted in multiple instances being constructed at startup, making the time to enumerate plugins on slow media significantly worse.

Change 3528415 by Ben.Marsh

	UAT: Remove \r characters from the end of multiline log messages.

Change 3528427 by Ben.Marsh

	EC: Fix spaces being converted to tabs at start of line in failure emails (by Gmail), and wrap following lines at the same indent.

Change 3528485 by Ben.Marsh

	EC: Remove zero-width word break characters from slashes in notification emails; can cause really hard to debug problems when copy pasted into other places.

Change 3528505 by Steve.Robb

	PR #3755: MallocProfiler - Remove subfolder from profiling save directory (Contributed by Josef-CL)

	PR #3760: Fix typo (Contributed by jesseyeh)


Change 3528792 by Steve.Robb

	PR #3764: MallocProfiler - Refactoring Scopelock (Contributed by Josef-CL)


	#jira UE-46962

Change 3528941 by Robert.Manuszewski

	Fixed lazy object pointers not being updated for streaming sub-levels in PIE. Fixed lazy pointers returning object that is still being loaded which could lead to undefined behavior when client code started modifying the returned object.

	#jira UE-44996

Change 3530241 by Ben.Marsh

	UAT: Only pass -submit or -nosubmit to child instances of UAT if they were specified on the original command line. BuildCookRun uses this flag to determine whether to submit, rather than just whether to allow submitting, so we shouldn't pass an inferred value.

Change 3531377 by Ben.Marsh

	Plugins: Allow plugins to specify a list of supported target platforms, which is propagated to any .uproject file that enables it.

	This has several advantages over the per-module platform whitelist/blacklist:

	* Platform-specific .uplugin files can now be excluded when staging other platforms. Previously, it was only possible to determine which platforms a plugin supports by reading the plugin descriptor itself. Now that information is copied into the .uproject file, so the runtime knows which plugins to ignore.
	* References to dependent plugins from platform-specific plugins can now be eliminated.
	* Plugins containing content can now be unambiguously disabled on a per-platform basis (having no modules for a platform does not confer that a plugin doesn't support that platform; now it is possible to specify supported platforms explicitly).
	* The editor can load any plugins without having to whitelist supported editor host platforms.

	UE4 targets which support loading plugins for target platforms can set TargetRules.bIncludePluginsForTargetPlatforms (true for the editor by default, false for any other target types). This defines the LOAD_PLUGINS_FOR_TARGET_PLATFORMS macro at runtime, which allows the plugin system to filter which plugins to look for at runtime.

	Any .uproject file will be updated at startup to contain the list of supported platforms for each referenced plugin if necessary.

Change 3531502 by Jin.Zhang

	Add support for GPUCrash #rb

Change 3531664 by Ben.Marsh

	UBT: Change output format from C# JSON writer to match output by the engine.

Change 3531848 by Ben.Marsh

	UAT: Add script to resaving all project descriptors under a folder, embedding information for any supported platforms for the plugins they enable.

Change 3531869 by Ben.Marsh

	UAT: Add parameter to the ResaveProjectDescriptors command to update the engine association field.

Change 3532474 by Ben.Marsh

	UBT: Use the same mechanism as UAT for logging exceptions.

	Set_Add and Map_Add no longer have a return value.
	FScriptSet::Find and FScriptMap::Find functions are now FindIndex.
	FScriptSetHelper::FindElementFromHash is now FindElementIndexFromHash.

	 - Point all builds directly at UBT rather than the batch files
	 - Adjust mac build tasks to run through mono

Change 3532924 by Ben.Marsh

	UAT: Set the UAT working directory immediately on startup. This ensures that any command line arguments containing paths are resolved consistently to the branch root.

Change 3535234 by Graeme.Thornton

	VSCode - Pass intellisense system a list of paths to use for header resolution

Change 3535247 by Graeme.Thornton

	UBT - Add a ToString to ProjectFile.Source file to help with debugger watch presentation

Change 3535376 by Graeme.Thornton

	VSCode
	 - Added build jobs for C# projects
	 - Linked launch tasks to relevant build task

Change 3537083 by Ben.Marsh

	EC: Change P4 swarm links to start at the changelist for a build.

Change 3537368 by Graeme.Thornton

	VSCode - Various updates to get PC and Mac C++ projects building and debugging.
	 - Some other changes to C# setup to allow compilation. Debugging doesn't work.

Change 3539775 by Ben.Marsh

	Plugins: Various fixes to settings for enabling plugins.

	* Fix crash on startup when trying to disable a missing plugin (was keeping pointers to elements in the project's plugin reference array, which may be modified if a plugin is disabled).
	* Revert fix to set PluginDescriptor.bRequiresBuildPlatform = true by default. This was the originally intended behavior, but it was accidentally defaulted to false during serialization unless specified in the .uplugin file. Many plugins may rely on this behavior (they may not declare asset classes otherwise, for example, which could result in loss of data), so change the default value to false instead. Also fixes popups to disable platform-specific plugins if platform SDKs are not installed.
	* Fix plugins which are referenced but do not exist not showing the appropriate prompt to disable them.

Change 3540788 by Ben.Marsh

	UBT: Add support for declaring custom pre-build steps and post-build steps from .target.cs files. Similarly to the custom build steps configurable from .uproject and .uplugin files, these specify commands which will be executed by the host platform's shell before or after a build. The following variables are expanded within the list of commands before execution: $(EngineDir), $(ProjectDir), $(TargetName), $(TargetPlatform), $(TargetConfiguration), $(TargetType), $(ProjectFile).

	Example usage:

	public class UnrealPakTarget : TargetRules
	{
		public UnrealPakTarget(TargetInfo Target) : base(Target)
		{
			Type = TargetType.Program;
			LinkType = TargetLinkType.Monolithic;
			LaunchModuleName = "UnrealPak";

			if(HostPlatform == UnrealTargetPlatform.Win64)
			{
				PreBuildSteps.Add("echo Before building:");
				PreBuildSteps.Add("echo This is $(TargetName) $(TargetConfiguration) $(TargetPlatform)");

				PostBuildSteps.Add("echo After building!");
				PostBuildSteps.Add("echo This is $(TargetName) $(TargetConfiguration) $(TargetPlatform)");
			}
		}
	}

	Add callback into FMacPlatformMisc::PumpMessages() from FMacPlatformApplicationMisc::PumpMessages().

	#jira UE-47449

Change 3545954 by Gil.Gribb

	Fixed a critical crash bug relating to a race condition in async package summary reading.

Change 3545968 by Ben.Marsh

	UAT: Fix incorrect username in BuildGraph <Submit> task. Should use the username from the Perforce environment, not assume the logged in user name is the same.

	#jira UE-47419

Change 3545976 by Ben.Marsh

	EC: Delete the AutoSDK client if the directory doesn't exist. When we format build machines, we need to force everything to be resynced from scratch.

Change 3546185 by Ben.Marsh

	Hacky fix for deployment on IOS/TVOS. Since deployment directly references the NonUFS manifest files that are written out, merge all the SystemNonUFS files back into the NonUFS list after the regular NonUFS files have been remapped.

Change 3547084 by Gil.Gribb

	Fixed a critical race condition in the new async loader. This was only reproducible on IOS, but may affect other platforms.

Change 3547968 by Gil.Gribb

	Fixed critical race which potentially could cause a crash in the pak precacher.

Change 3504722 by Ben.Marsh

	BuildGraph: Improved tracing for error messages. All errors are now propagated as exceptions, and are tagged with additional context information about the task currently being run.

	For example, throwing new AutomationException("Unable to write foo.txt") from SetVersionTask.Execute is now displayed in the log as:

	ERROR: Unable to write to foo.txt
	         while executing <SetVersion Change="0" CompatibleChange="0" Branch="Unknown" Promoted="True" />
	         at Engine\Build\InstalledEngineBuild.xml(91)
	       (see D:\P4 UE4\Engine\Programs\AutomationTool\Saved\Logs\UAT_Log.txt for full exception trace)

Change 3512255 by Ben.Marsh

	Rename FPaths functions with a "Game" prefix (GameDir(), GameContentDir(), etc...) to have a "Project" prefix (ProjectDir(), ProjectContentDir(), etc...) for clarity with non-game uses of UE4. Old functions still exist but are deprecated.

Change 3512332 by Ben.Marsh

	Rename "Game" functions in FApp to be "Project" functions (FApp::GetGameName() -> FApp::GetProjectName(), etc...) for clarity with non-game uses of UE4.

Change 3512393 by Ben.Marsh

	Rename FPaths::GameLogDir() to FPaths::ProjectLogDir().

Change 3513452 by Ben.Marsh

	Plugins: Rename EPluginLoadedFrom::GameProject to EPluginLoadedFrom::Project.

Change 3516262 by Ben.Marsh

	Add support for a "Mods" folder distinct from the project's "Plugins" folder, instead of using the bIsMod flag on the plugin descriptor.

	* Mods are enumerated similarly to regular plugins, but IPlugin::GetType() will return EPluginType::Mod.
	* The DLCName parameter to BuildCookRun and the cooker now correctly finds any plugin in the Plugins or Mods directory (or any subfolders).

Change 3517565 by Ben.Marsh

	Remove fixed engine version numbers from OSS plugins.

Change 3518005 by Ben.Marsh

	UAT: Remove the bUFSFile parameter from DeployLowerCaseFilenames(). Every platform returns false if the argument is false.

Change 3518054 by Ben.Marsh

	UAT: Use an enum to direct whether all directories should be searched when finding files to stage, rather than a bool. Having so many optional boolean arguments makes code unreadable and refactoring hard.

Change 3524496 by Ben.Marsh

	Start moving GUI application code into a separate static platform class, hopefully ultimately removing it from Core.

Change 3524641 by Ben.Marsh

	Move more functionality related to windowed/graphical applications into FPlatformApplicationMisc.

Change 3528723 by Steve.Robb

	MoveTemp now static asserts if passed a const reference or rvalue.
	MoveTempIfPossible still follows the old (std::move) rule, which is useful for templates where the nature of the argument is not obvious.
	Fixes to violations of these new rules.

Change 3528876 by Ben.Marsh

	Move FPlatformMisc::ClipboardCopy and FPlatformMisc::ClipboardPaste to FPlatformApplicationMisc::ClipboardCopy and FPlatformApplicationMisc::ClipboardPaste.

Change 3529073 by Ben.Marsh

	Add script to package ShooterGame for any platforms.

Change 3531493 by Ben.Marsh

	Update platform-specific plugins to declare the target platforms they support.

Change 3531611 by Ben.Marsh

	UAT: Add a ResavePluginDescriptors command, which resaves all plugin descriptors under a given folder, removing any outdated fields and rewrites them in a consistent style. Many plugins in the wild contain redundant or no-longer used fields due to using our plugins as templates.

Change 3531868 by Ben.Marsh

	Resaving project descriptors to remove invalid fields.

Change 3531983 by Ben.Marsh

	UAT: Simplify logic for staging code, and add validation against shipping files in restricted folders.

	* Added a new SystemNonUFS type for staged files, which excludes files from being remapped or renamed by the platform layer.
	* Replaced the DeplyomentContext.StageFiles() function with simpler overloads for particular use cases (options for remapping are replaced with the SystemNonUFS file type)
	* Config entries in the [Staging] category in DefaultGame.ini file allow remapping one directory to another, so restricted content can be made public in packaged builds (Example syntax: +RemapDirectory=(From="Foo/NoRedist", To="Foo"))
	* An error is output if any restricted folder names other than the output platform are in the staged output.

Change 3540315 by Ben.Marsh

	UAT: Moving StreamCopyDescription command into a NotForLicensees folder, since it's only meant to be used by engine developers.

Change 3542410 by Ben.Marsh

	UBT: Deprecate accessing properties through BuildConfiguration.* or UEBuildConfiguration.* from .target.cs files. These have been aliases to the current TargetRules instance for several releases already.

Change 3543018 by Ben.Marsh

	UBT: Deprecate the BuildConfiguration and UEBuildConfiguration aliases from the ModuleRules class. These have been implemented as an alias ot the ReadOnlyTargetRules instance passed to the constructor for several engine versions.

Change 3544371 by Steve.Robb

	Fixes to TSet_Add and TMap_Add BPs.

MAJOR FEATURES + CHANGES
==========================

Change 3209340 on 2016/11/23 by Ben.Marsh

	Convert UE4 codebase to an "include what you use" model - where every header just includes the dependencies it needs, rather than every source file including large monolithic headers like Engine.h and UnrealEd.h.

	Measured full rebuild times around 2x faster using XGE on Windows, and improvements of 25% or more for incremental builds and full rebuilds on most other platforms.

	  * Every header now includes everything it needs to compile.
	        * There's a CoreMinimal.h header that gets you a set of ubiquitous types from Core (eg. FString, FName, TArray, FVector, etc...). Most headers now include this first.
	        * There's a CoreTypes.h header that sets up primitive UE4 types and build macros (int32, PLATFORM_WIN64, etc...). All headers in Core include this first, as does CoreMinimal.h.
	  * Every .cpp file includes its matching .h file first.
	        * This helps validate that each header is including everything it needs to compile.
	  * No engine code includes a monolithic header such as Engine.h or UnrealEd.h any more.
	        * You will get a warning if you try to include one of these from the engine. They still exist for compatibility with game projects and do not produce warnings when included there.
	        * There have only been minor changes to our internal games down to accommodate these changes. The intent is for this to be as seamless as possible.
	  * No engine code explicitly includes a precompiled header any more.
	        * We still use PCHs, but they're force-included on the compiler command line by UnrealBuildTool instead. This lets us tune what they contain without breaking any existing include dependencies.
	        * PCHs are generated by a tool to get a statistical amount of coverage for the source files using it, and I've seeded the new shared PCHs to contain any header included by > 15% of source files.

	Tool used to generate this transform is at Engine\Source\Programs\IncludeTool.

MAJOR FEATURES + CHANGES
==========================

Change 3059740 on 2016/07/21 by Ben.Marsh

	Format license violations on separate lines rather than as a single multi-line string, so they can be parsed out correctly by the EC log parser.

Change 3063115 on 2016/07/25 by Ben.Marsh

	Add missing projects to Mono AutomationTool solution.

Change 3067125 on 2016/07/27 by Ben.Marsh

	Clean up and document the engine versioning system.

	* Version.h has a summary of all the different versioning concepts in UE4, as well as an explanation of what all the macros do.
	* VersionLocked.h has been removed. ENGINE_NET_VERSION and ENGINE_REPLAY_VERSION can be overriden directly in Version.h if necessary.
	* Added explicit macros for ENGINE_CURRENT_CL_VERSION And ENGINE_COMPATIBLE_CL_VERSION. The MODULE_API_VERSION macro is now defined to be the same as ENGINE_COMPATIBLE_CL_VERSION.
	* Build/Build.version now includes the compatible CL version, so it can be determined without having to parse header files inside MacToolChain.cs.
	* UpdateLocalVersion UAT command now exposes a -CompatibleCL=... argument to update ENGINE_COMPATIBLE_CL_VERSION and the CompatibleChange property in Build.version.
	* SetVersion BuildGraph task now has a CompatibleChange="" attribute to update ENGINE_COMPATIBLE_CL_VERSION and the CompatibleChange property in Build.version.
	* VersionFileUpdater now makes an effort to parse tokens matching the macros it's going to overwrite, rather than requiring exact matches in whitespace in Version.h.
	* Running UpdateLocalVersion now syncs files to revision 0 before writing if P4 is enabled, similarly to UGS, or fails if they are not writable.

Change 3067242 on 2016/07/27 by Ben.Marsh

	Fix UGS showing a build failure/warning dialog immediately if you submit while the build is yellow/red. Now ignores builds before your last submitted CL.

Change 3068116 on 2016/07/28 by Ben.Marsh

	Add a small Windows utility to terminate all running processes under a given root directory, and run it before and after every sync. Mean to fix instances where zombie editor processes do not terminate correctly and cause subsequent syncs to fail.

Change 3068246 on 2016/07/28 by Ben.Marsh

	UGS: Improvements to 'Clean Workspace' dialog - empty folders are now set to be deleted by default, and added a context menu to select all/none/empty/default for a subtree, as well as to open Windows explorer at that location.

Change 3068573 on 2016/07/28 by Ben.Marsh

	Attempt to fix AppDomain unload errors; suspect caused by delay to terminate child processes when managed exception is thrown on child threads. Now waits for the currently running threads to finish executing before quitting.

Change 3068575 on 2016/07/28 by Ben.Marsh

	Respect the -noxge command-line argument when compiling UHT.

Change 3068665 on 2016/07/28 by Ben.Marsh

	Delete any DLLs in output folders which share names with build products. The Windows loader reads DLLs from the first location it finds a file with a matching name, so we need to ensure that it doesn't load stale DLLs when output directories are changed (moving a module into a plugin, for example).

Change 3073316 on 2016/08/02 by Ben.Marsh

	CoreUObject: Replace header guards with #pragma once directives.

Change 3073325 on 2016/08/02 by Ben.Marsh

	CoreUObject: Manually untangle a few circular includes around ObjectBase.h and Class.h to allow making them into IWYU-style headers.

Change 3074391 on 2016/08/02 by Ben.Marsh

	GitHub #2646: Always allow programs to build as part of non-game solution configurations.

Change 3075123 on 2016/08/03 by Richard.Fawcett

	Ensure that zip files created outside of Ionic Zip can be unzipped with CommandUtils.UnzipFiles

	Zip files created with 7-zip, WinRAR, and Windows Explorer all contain entities for directories, not just the files in them.  Code in CommandUtils.UnzipFiles made the assumption that all entities in the zip file were files, and an exception was being thrown on encountering a directory.

Change 3075848 on 2016/08/03 by Ben.Marsh

	UBT: Fix a few cases where it's possible to construct a non-canonical DirectoryReference - root directories on Windows must always have a terminating slash, but any other directories must note. DirectoryInfo and Path.GetFullPath() do not enforce this requirement.

Change 3075850 on 2016/08/03 by Ben.Marsh

	UBT: Fix UHT failures when running with -nopch.

Change 3077058 by Ben.Marsh

	UHT: Remove the auto-generated ObjectBase.h include from generated header files. Was originally added to allow doxygen to parse headers more easily, but was switched to parsing the file only as part of parent files instead.

Change 2790858 on 2015/12/04 by Ben.Marsh

	Fix ERRORLEVEL not being correctly returned by build.bat, causing failed builds to be treated as succeeded builds when launched from Visual Studio.

	#codereview Wes.Hunt

Change 2792683 on 2015/12/07 by Matthew.Griffin

	Removed some usages of RunningRocket() function

	Checks for whether engine tools need rebuilding should be ignored in all installed engine builds.
	New Intermediate folders should be within project directory and engine's should not be removed when engine installed.

Change 2794194 on 2015/12/08 by Matthew.Griffin

	Removed IsRocket function.
	Changed IsEngineInstalled so that -NotInstalledEngine will always disable installed engine behavior.

Change 2801483 on 2015/12/14 by Matthew.Griffin

	Removed uses of UnrealBuildTool.RunningRocket()

	Mac Tool chain test was down to Engine libraries being pre-compiled
	Allow Third Party dependencies in any monolithic target, not just games
	All installed engine builds should use shared build environment
	Removed test no longer needed now that projects from installed builds have game targets
	Include engine source if it exists in any installed build to improve intellisense in VCProjects

Change 2803276 on 2015/12/15 by Matthew.Griffin

	Removed Rocket switch from ProjectParams as it can always check Automation.RunningRocket()
	Removed bGeneratingRocketProjectFiles from ProjectFileGenerator as it can always check UnrealBuildTool.RunningRocket()
	Changed a few usages to IsEngineInstalled where obvious

Change 2814190 on 2016/01/03 by Ben.Marsh

	Convert ParallelExecutor to managed code, so we can use it trivially from UAT without having to compile with UBT first. Should be moved into UBT at some point.

	Also add a support class for creating managed child processes, which are terminated automatically if the parent process is closed. Currently only implemented on Windows, using P/Invoke. Also allows setting priority level of the process, which could replace the hacky way that we determine the physical processor count in UBT.

Change 2822503 on 2016/01/10 by Wes.Hunt

	AnalyticsET now uses the Data Router protocol.
	* Automatically detects configs that try to use the old endpoint and routes them to the new endpoint. This code is temp until internal games merge the code and have a chance to update their configs.
	* There is a new attribute on BeginSession called "LegacyURL" that is "true" if the code needs to have its configs updated, as well as a LogAnalytics warning.
	* Updated EngineAnalytics and AutomationAnalytics providers to use the new URL and specify any appropriate new, optional config values.
	* Update CrashReporter provider to use new URL and simplified it's provider configuration (now uses AnalyticsET config struct directly).
	Removed recently added GetUE4TypeOverride and moved it to the one place in Engine that needs it.
