============================
  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

	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

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 can now load any runtime modules, as long as they are whitelisted.
	* 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.

	Plugins that are compatible with a program now need to list that program in the SupportedPrograms list, and whitelist any modules that should load for that program.

	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).

	It's now possible to filter clusters that get logged with verbose cluster logging enabled (UE_GCCLUSTER_VERBOSE_LOGGING=1) by objects within them by specifying -DumpClustersWithObjects=ObjectName1,ObjectName2 in the command line

Change 4257822 by Ben.Marsh

	Fixes for PlatformShowcase compile errors.

Change 4258771 by Ben.Marsh

	UBT: Fix project files not being generated for foreign projects when creating .stub files.

	#jira UE-62462

Change 4258790 by Ben.Marsh

	UBT: Clean up the logic around generating project files before creating a stub IPA, so that it fails loudly if project files do not exist, and can accept target names not matching project names.

Change 4259276 by Ben.Marsh

	UBT: Make it an error if a framework doesn't exist, rather than failing silently. Also remove some remote toolchain stuff that's no longer necessary.

Change 4259280 by Ben.Marsh

	UBT: Fix embedded framework zips not being uploaded for plugins.

Change 4260559 by Ben.Marsh

	UGS: Update version.

Change 4261160 by Robert.Manuszewski

	MediaPlaylist will now be added to root set if the owning MediaPlayer is in the disregard for GC set (fixes GC assumption violation crash)

	UBT: Remove some leftover functions for handling the remote toolchain.

Change 4261530 by Ben.Marsh

	UBT: Speculative fix (and better error reporting) for IOS mobile provision not being found in CIS.

Change 4261611 by Ben.Marsh

	UBT: Downgrade warning to a log message, since it appears when generating project files.

Change 4261710 by Ben.Marsh

	Remove assert that GLogConsole is set; it won't be for command line utilities that don't depend on ApplicationCore.

	#jira UE-62545

Change 4261831 by Ben.Marsh

	Fix compile errors due to missing include path when hot-reloading a module from the editor. There are not necessarily source files to compile when -modulewithsuffix is specified on the command line, which was results in GeneratedCodeWildcard not being set.

	#jira UE-62463, UE-62384

Change 4262723 by Ben.Marsh

	Whitelist plugins that need to be loaded by UFE.

	#jira UE-62564

Change 4265444 by Ben.Marsh

	Fix incorrect executable name for DebugGame configurations in Xcode.

	#jira UE-62574

Change 4265892 by Ben.Marsh

	Fix incremental compile failures due to dependency checking for unity files. CachedIncludePaths was not correctly being set on file items, so dependencies were being ignored.

	#jira UE-62575, UE-62603, UE-62597

Change 4266019 by Josh.Adams

	- Fixed the CopyAction for runtime dependencies that need to be copied to different location, on non-XGE

Change 4266264 by Ben.Marsh

	Remove override for the __IPHONE_OS_VERSION_MIN_REQUIRED macro on TVOS.

	This macro is already defined by system headers (in <AvailabilityInternal.h>). Now that we support PCHs on IOS and TVOS, manually defining this macro results in it being defined three times (once for the PCH, once by AvailabilityInternal.h, and once by the force-included list of definitions for the source file being built). The errors for redefining the macro in AvailabilityInternal.h are suppressed due to it being a system header, but the error for redefining it for the source file being compiled are not.

	#jira UE-62578

Change 4266273 by Ben.Marsh

	Fixes incremental build failure when compile arguments for PCH have changed on IOS/TVOS. Compile action needs to have a dependency on PCH build action.

Change 4266614 by Graeme.Thornton

	Fix crash when cooking nativized blueprints due to removal of child cooker system.

Change 4266763 by Ben.Marsh

	Always build UnrealPak when building client targets. The ProjectParams.Pak option is not reliable, because it can be forced on later by the target platform.

	#jira UE-62584

Change 4267985 by Robert.Manuszewski

	When iterating with ForEachObjectWithouter, don't lock the entire has table but only the hash bucket that is currently being iterated

	#jira UE-62600

Change 4268558 by Robert.Manuszewski

	PurgeLegacyBlueprints will no longer be called from within ForEachObjectWithOuter is it renames objects that reside in hash tables that are being iterated over which may lead to undefined behavior.

	#jira UE-62600

Change 4269011 by Chad.Garyet

	- Fixing Wildcard match issue, the change to ugsapi sends projects as //Depot/Stream instead of //Depot/Stream/
	  Wildcard match was only substringing to 3 chars.
	- Checking in the change a while back that increases the number of queried jobs up to 432 based on some maths from Bob about how many builds we want to grab
	Published to ugsapi server 8/8/17
	#jira none

Change 4270788 by Ben.Marsh

	Fix IOS provisioning data being using when remote compiling on TVOS.

	#jira UE-62705

Change 4271916 by Ben.Marsh

	Tag the XGEControlWorker executable as a build product after compiling SCW, to make sure it's included in the UGS zip file.

Change 4271934 by Ben.Marsh

	Upload all static libraries in plugin folders as part of remote builds.

	#jira UE-62694

Change 4273368 by Ben.Marsh

	Fix Slate dependencies not being enumerated, and rules assembly not being rebuilt when building remotely.

	#jira UE-62705

Change 4274049 by Ben.Marsh

	Always parse the team UUID out of the mobile provision when doing a remote compile. The provision installed on the remote Mac (and selected for signing) may be different.

	#jira UE-62751

Change 4274823 by Ben.Marsh

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

Change 4275838 by Ben.Marsh

	Fix BuildVersion string not being passed through from <SetVersion> task. Also add a -BuildVersion command line argument to UBT to override it for a particular build.

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

	Vast simplification of TFunction, making it smaller in footprint, easier to follow and extend, and more correct.
	TUniqueFunction added, which is a move-only TFunction which can hold move-only functors.
	Fix for UWidgetBlueprint::ForEachSourceWidget() which should never have compiled but did.
	FFunctionGraphTask and TFuture<> updated to use TUniqueFunction to make them more general.
	TArray::HeapPop() made to work with move-only types.

Change 4082591 by Ben.Marsh

	Move the Log class from UBT to DotNetUtilities.

Change 4083236 by Ben.Marsh

	Add a Log.WriteException() method to dump an exception message to the console (and write the exception trace to the log)

Change 4084107 by Ben.Marsh

	UAT: Remove the unused -SkipHeader argument to UE4Build.

Change 4089771 by Steve.Robb

	GitHub #4743 : modified VirtualAlloc function flag

	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 3974233 by Rex.Hill

	Optimized BuildStaticMeshVertexAndIndexBuffers and TEdgeBuilder

Change 3974234 by Rex.Hill

	Reduced number of calls to SaveRawMesh and LoadRawMesh

Change 3974235 by Rex.Hill

	Optimized SaveRawMesh by pre-allocating buffer

Change 3981370 by Jamie.Dale

	Added support for deprecated (renamed) classes, structs, enums, functions, and properties in Python

	The glue code generation will now use the existing redirects system to build deprecated entries for old names. You can also specify deprecated names to the ScriptName and ScriptMethod meta-data values by adding extra semi-colon separated entries (the first entry is the current name).

	Accessing deprecated objects in Python leads to a deprecation warning when developer mode is enabled.

Change 3983875 by Jamie.Dale

	Exposed some asset registry functions that may be useful in a commandlet environment

Change 3983901 by Jamie.Dale

	Hoisted some AssetData helpers onto the struct in Python

Change 3988367 by Jamie.Dale

	Python now honors EditInstanceOnly and EditDefaultsOnly when setting property values

Change 3988369 by Jamie.Dale

	Exposed generic get_default_object function that takes a type and returns you the CDO

	This is needed for types that aren't natively exposed to Python (such as Blueprint generated types)

Change 3989890 by Jamie.Dale

	Moved BlutilityActor to be Private in EditorScriptingUtils

	This can be removed once it's no longer needed.

Change 3989900 by Jamie.Dale

	Updated EditorScriptingUtilities to use the Public/Private folder structure for source code

Change 3990082 by Anousack.Kitisa

	Added plugin for Shotgun integration in Unreal.

	#jira UEENT-959

Change 3990783 by Anousack.Kitisa

	Changed ShotgunMenuItem to a struct.

Change 3991139 by Jamie.Dale

	Minimized use of GUnrealEd (favoring GEditor) so that this code can be used by commandlets

	Removed redundant usages of GEditor/GUnrealEd from within UEditorEngine itself, and fixed cases where null data was being accessed. Testing that loading, saving, and creating a new blank map will now work in a commandlet without crashing.

Change 3993189 by Jamie.Dale

	Fixed some mismatched return types

Change 3993191 by Jamie.Dale

	Inital support for taking the GIL at key points where external C code calls into Python

Change 3993683 by Patrick.Boutot

	[LTC]
	Add a CustomTimeStep that decode a LinearTimecode from the MediaSource. The MediaPlayer need to support buffering and should not run late since it's used to tick the engine time.
	Update DropTimecode to use the new Timecode structure in TimeManagement.

Change 3994430 by Jamie.Dale

	Adjusted how inline structs work so that types known at compile time can inline allocate without being fully hand-wrapped in Python

	They must now be registered via FPyWrapperTypeRegistry::RegisterInlineStructFactory before we start generating wrapped types

Change 3996083 by Jamie.Dale

	Added a distinct type for generated enum types so that you can query their available enum entries

Change 3998253 by conan.reis

	Remove redundant Perforce error output from the log

Change 4000307 by JeanMichel.Dignard

	Optimized FFbxImporter::ValidateAllMeshesAreReferenceByNodeAttribute()
	- Stored all scene nodes geometry ids in a set instead of looping on all scene nodes for every geometry. O(N) instead of O(N^2).
	- For 38685 scene nodes and 5417 geometry, the time went from 2 min 21.688 s to 0 min 0.098 s.

Change 4000605 by Jamie.Dale

	Added support for constant "hoisting"

	This allows you to tag a helper function that returns a constant with ScriptConstant meta-data (providing a potentially overridden name) to "hoist" that helper function to be a constant of the type it operates on when wrapped for Python (ScriptConstantHost can be used to host the constant on a struct rather than its own object).

Change 4001617 by Jamie.Dale

	Updated ScriptMethod and ScriptConstant to allow hoisting onto other classes as well as structs

	This allows you to have a runtime class be extended via methods in an editor-only module

Change 4005287 by Jamie.Dale

	Added a GIL lock when Slate Tick events call back into Python

Change 4005383 by Andrew.Rodham

	Sequencer: Initial scripting exposure and support

	First pass includes the following:
	  - Find/add/interate master tracks
	  - Find/add/interate bindings (both possessables and spawnables)
	  - Find/add/interate tracks on bindings
	  - Add/interate sections on tracks
	  - Get/Set section ranges

Change 4008609 by Jamie.Dale

	Added some missing native Python types to the documentation

	Native modules now build up a list of types and functions associated with them. This information is then passed through to the document generation to ensure that all exposed native types and functions are documented.

	In addition, any native Python module files are now assimilated into the unreal.py stub file and parsed so that they can be documented too.

Change 4008654 by Jamie.Dale

	Allow math operators to use the base type versions unless overridden

Change 4009740 by Patrick.Boutot

	Add BP function to convert a Timecode into a string.

Change 4009763 by Patrick.Boutot

	Update AudioCapture to retreive the SampleRate. Used by the LinearTimecode. Change the requested format from int16 to float since we converted it into that format later on.

Change 4009768 by Andrew.Rodham

	Removed explicit names from ScriptName methods, expanded sequencer scripting range functionality

Change 4009830 by Jamie.Dale

	Added support for UPARAM(ref) on arguments exposed to Python

	For standard functions, this just produces an input and output for the same argument (we can't mutate the input due to potential coercion).

	For ScriptMethod functions that use it on the 'self' argument, this will mark the function as "inline" and have the function apply the result of the 'self' argument back onto the 'self' instance after calling the function.

Change 4010034 by Jamie.Dale

	Added support for init_unreal.py start-up scripts

	These can be placed in any known sys.path in Python, including the Content/Python folders we automatically add, and the UnrealEngine/Python directory under the users home directory.

Change 4010422 by Jamie.Dale

	Improved errror reporting during Python generation

	It will now ensure if a debugger is attached to draw programmer attention to an error.

Change 4010498 by Patrick.Boutot

	Remove unnecessary loop Timecode.ToFrameNumber()

Change 4011312 by Jamie.Dale

	Duplicate deprecated names will no longer assert during Python glue generation

	They will now log a warning and continue

Change 4012068 by JeanMichel.Dignard

	Allow to render thumbnails for newly created packages.
	- To render a thumbnail, you either need a customer thumbnail renderer or a cached thumbnail. Querying cached thumbnails fails for newly created packages because it calls DoesPackageExist which check on disk. This call is unnecessary since we're relying on FindPackage which only works for packages that are loaded in memory.

Change 4013781 by Jamie.Dale

	FFrame::KismetExecutionMessage (or LogRuntimeError or LogRuntimeWarning) will now produce Python exceptions

	You can use these to emit warnings or errors from UFunctions wrapped for scripting, and when called from Python they will produce a Python exception (for errors), or Python warning (for warnings).

Change 4014337 by Jamie.Dale

	Struct coercion now errors if you provide a sequence with too many elements

	This also makes sure that PyConversion doesn't set an error state if ESetErrorState::No is passed (which could have previously happened from type casting calls).

Change 4015290 by Andrew.Rodham

	Sequencer: Moved runtime functionality from ISequencerChannelInterface to IMovieSceneChannelInterface

	  - Rename IBatchChannelInterface to IMovieSceneChannelInterface
	  - Removed MovieScene::Dilate()
	  - Added TMovieSceneChannelTraits::SupportsDefaults to automatically stub out functions relating to channel defaults

Change 4015664 by Jamie.Dale

	Renamed ScriptMathOp meta-data to ScriptOperator

Change 4016230 by Jamie.Dale

	Fixed incorrect make/break path in Importance Sampling Library (for Importance Texture)

Change 4017326 by Jamie.Dale

	Added make and break support in Python

	Structs that have a native make function will now use this as their constructor. This also adds support for breaking a struct into a tuple, either via a native break function, or via generic property enumeration.

Change 4017551 by Jamie.Dale

	Removed redundant outer parameter from find/load_asset/package

Change 4018594 by Jamie.Dale

	Added ScriptMethodSelfReturn as an alternative to UPARAM(ref)

	These two function signatures produce the same behavior and have the same cost in Python, the only difference is how they appear to Blueprints (and Blueprints seem to favor non-reference functions).

	UFUNCTION(..., meta=(ScriptMethod))
	static void DoThing(UPARAM(ref) FThingType&, int32);

	UFUNCTION(..., meta=(ScriptMethod, ScriptMethodSelfReturn))
	static FThingType DoThing(FThingType, int32);

Change 4020956 by Anousack.Kitisa

	Added Shotgun to the Level Editor/World Outliner and Content Browser context menus when there's a selected actor or asset.

	#jira UEENT-1219

Change 4021986 by Anousack.Kitisa

	Used the Python startup scripts mechanism to launch the Shotgun bootstrap script.

	Related to Jira UE-57896.

Change 4022993 by Jamie.Dale

	Added support for extra operators on Python structs

	You can now expose bool conversion and comparison operators (==, !=, <, <=, >, >=) in addition to the previous set of math operators. As part of this there is now stricter signature validation when generating the Python binding.

Change 4023226 by Jamie.Dale

	Added Make and Break function for FSoftClassPath

Change 4023348 by Jamie.Dale

	Exposed some methods and operators for PrimaryAssetId and PrimaryAssetType

Change 4027911 by Jamie.Dale

	Cross-outer redirects are no longer applied in Python

	#jira UETOOL-1382

Change 4029618 by JeanMichel.Dignard

	Unreal Studio UX
	- Made "Unreal Studio" the default tab in the new project wizard if we're using an installed enterprise build.
	- Create new projects as enterprise projects if we're using an insalled enterprise build.

	#jira UEENT-1231, UEENT-796

Change 4030217 by Jamie.Dale

	Exposed ScopedSlowTask to Python

	#jira UETOOL-1375

Change 4030784 by Matt.Hoffman

	Sequencer curve editor now shows vertical axis labels.

	#jira UE-58160

Change 4030858 by JeanLuc.Corenthin

	Expose LOD creation thru Python:
	- Create one struct to hold onto reduction settings per LOD
	- Create one struct to hold onto an array of reduction settings and a parameter to enable of disable automatic computation of screen size
	- Create new method to apply reduction settings to an array of StaticMeshActors

	#jira UEENT-1232

Change 4032239 by Jamie.Dale

	Cleanup pass over wrapped structs

	- Code dealing with reflected structs now uses UScriptStruct rather than UStruct.
	- The old PyConversion::NativizeStruct and PyConversion::PythonizeStruct have been renamed to PyConversion::NativizeStructInstance and PyConversion::PythonizeStructInstance.
	- New PyConversion::NativizeStruct and PyConversion::PythonizeStruct functions have been added to convert an object (or Python type) to a UScriptStruct (akin to what PyConversion::NativizeClass and PyConversion::PythonizeClass does for UClass).

	Various pieces of documentation and cleanup.

Change 4037112 by Max.Chen

	Sequencer: Added some missing RF_Transactional flags to newly created sections.

Change 4037121 by Max.Chen

	Sequence Recorder: Timecode recording

	Introduced an FSourceTimecode which is saved as editor only data to the MovieSceneSection and MovieScene. FSourceTimecode consists of an FFrameNumber delta that correlates the section's initial start time to an FTimecode. The FFrameNumber is adjusted whenever the section is moved.

	One use case for this is through sequence recorder, which captures the timecode at the start of recording and saves an FSourceTimecode per movie scene section it creates. If the section is moved, it can always be returned to its source timecode by the section's right click menu, "Sync to Source Timecode".

	#jira UESEQ-406

Change 4038462 by Jamie.Dale

	Added support for using Python callables with delegates

	All the "x_function" methods on delegates and multicast delegates now have an "x_callable" equivalent that take a Python callable (we attempt basic validation of the signature, but that only allows us to check the input argument count is what we expect).

	Internally the callable is wrapped in a UObject, so certain GC restrictions are present (and is why coercion is disabled for callables). Delegates wrapped in Python (including as a direct property of an object or struct, or inside a container) will be kept alive via the Python reference collection, however once there are no Python references left the proxy object will be allowed to die unless something external has taken a reference to the proxy object.

	- Focus should no longer be set when the settings menu is open

Change 4041823 by Jamie.Dale

	Made ScriptOperator more relaxed about its signature validation for defaulted input parameters

	Existing Blueprint exposed operator functions may both default required arguments, and add additional default arguments. ScriptOperator will now accept both of these as long as there are enough arguments, but not too many non-defaulted arguments.


Change 4042956 by James.McNatton

	VirtualCamera bug fixes related to focus plane visualization
	- Removed extra focus plane that was being displayed

Change 4047714 by Max.Chen

	Sequencer: Resolved merge conflicts with Dev-Sequencer

Change 4048150 by Jamie.Dale

	Fixed single-culture PO import/export failing

	#jira UE-47079

Change 4048653 by Andrew.Rodham

	Sequencer: Automatic re-evaluation is now suppressed for external changes that modified only default values on channels

	  - The issue is that moving an object that is partially-keyed in sequencer, with auto-key off, will set default values for the non-keyed channels. Doing so will dirty the sequence, which causes a re-evaluation, which re-evalutes the keyed channels, which effectively undoes the external change.
	  - This is now fixed by suppressing the automatic re-evaluation for a specific signature of a specific sequence, if that is the only thing that has dirtied the sequence. Any subsequent changes to the sequence will cause a re-evaluation, and the suppression to be wiped.

	#jira UE-57519
	#jira UE-58487

Change 4048814 by Jamie.Dale

	Fixed syntax error if an enum had an unknown value

Change 4048819 by Jamie.Dale

	Fixed context leakage between the console and files, and import "unreal" by default now in the console

	#jira UETOOL-1379

Change 4049912 by Max.Chen

	Sequence Recorder: Minor recording group name improvements.
	- Initialize newly created actor group with existing actor group's base path.
	- When duplicating, use the current group's name as the base.
	- When typing in a name, if it fits the group format, the name should be allowable if it doesn't conflict with existing group names/assets.

Change 4049934 by Andrew.Rodham

	Sequencer: Minor clean-up of sequencer interfaces and overloads

	  - Replaced remaining instances of void* with FMovieSceneChannel* now that we mandate a common base class
	  - Changed remaining explicit calls to SetDefault to SetChannelDefault overload so it works correctly with the SupportsDefaults trait

	Sequencer: Allow actor components for synchronization

	#jira UE-58468

Change 4050900 by Max.Chen

	Sequence Recorder: Don't create a spawn section if the object is a possessable

	#jira UE-58272

Change 4050904 by Max.Chen

	Curve Editor: Fix for evaluation a section of time when one key is non-weighted and the other is weighted.  What we do is evaluate them both as being weighted, but we don't have the weight value for the non-weighted tangent. The weight of the non-weighted tangent is implicilty 1/3rd the distance between the two points, so we just calculate that if needed.

	#jira UE-58573

Change 4050905 by Max.Chen

	Curve Editor: When calculating vertical extents find feature points where slopes are zero and check them in addition to the keys if the curve is cubic. Curves now fit correclty vertically.

	Also changed fudge to 5% from 10% to match up old editor. Tighter fits seems better.

	#jira UE-58571

Change 4050972 by James.McNatton

	Packaging error issue introduce with CL 4054370.

	#jira UE-58749

Change 4055443 by Max.Chen

	Sequencer: Fix crash in adding filler shot

	#jira UE-58767

Change 4056577 by JeanMichel.Dignard

	Fixed crash with automation tests.
	We would bind the default UEditorEngine to Automation and on map load, it would call PIE on GEditor but with recent changes, PIE is called on this and the default UEditorEngine is not initialized so it would crash with a null GameViewportClass. Now we'll bind Automation on UEditorEngine InitializeObjectReferences so that we're in a good state and it's only called for GEditor.

	#jira UE-58792

Change 4057238 by Jamie.Dale

	Fixed crash when renaming Python generated classes or structs

Change 4058435 by Jamie.Dale

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

Change 3821754 by Jamie.Dale

	[Python] Class property conversion now goes through NativizeClass/PythonizeClass

	This allows it to coerce from Python wrapped object types

Change 3833107 by Patrick.Boutot

	Added functions to fill an existing DataTable from an existing CSV/JSON file.

Change 3835044 by Aaron.Carlisle

	Exposure for asset_import_data (editor property) and it's functions: extract_filenames and get_first_filename.

Change 3835466 by Patrick.Boutot

	Hide function from Python that need special compile command to be executed by the VM.

Change 3839237 by Jamie.Dale

	Added a way to inspect the full chain of properties that are currently being serialized by an archive

	You used to only have access to the leaf-most property, and while you could use its outer chain to inspect other properties within the same object/struct, you couldn't always get the full chain (eg, if you had an object containing a struct).

Change 3839974 by Jamie.Dale

	Make sure that SerializedProperty is copied correctly, as SetSerializedPropertyChain may set it to something else

Change 3842311 by Jamie.Dale

	Fixing potential null level assert

Change 3842313 by Jamie.Dale

	Updated settings editor to handle external properties

Change 3842316 by Jamie.Dale

	Allowing a console command to be given to GEditor/GEngine even if there's a player

	CL# 1848982 said it was to prevent multiple execution of stat commands, however that no longer seems to be an issue.

Change 3842867 by Jamie.Dale

	Added a way to generate diffs from editor transactions

	The notifications from these diffs are send to UObject::PostTransacted and FCoreUObjectDelegates::OnObjectTransacted.

	These notifications are typically generated when a transaction is "finalized", but can also be generated from "snapshots" (eg, to trap nodes being dragged in the world). They're also generated from normal undo/redo events.

Change 3844428 by Patrick.Boutot

	Move the SetMaterial code from the StaticMeshEditor to StaticMesh to be reusable by script.

Change 3845966 by Jamie.Dale

	Added support for minimal game RPC worlds

	These can be created in the editor and engine and exist to allow RPC communication via Unreal Networking in a way that is sandboxed from any other worlds that may be loaded (like the main game world)

Change 3848844 by Patrick.Boutot

	Expose EComponentMobility to blueprint.

Change 3854616 by Patrick.Boutot

	Add Custom way time step the engine loop. Will be used by the Synchronization of media for enterprise.

Change 3867158 by JeanMichel.Dignard

	UBT
	- Added the ability for dll programs to export symbols.

	#jira UEENT-541

Change 3872342 by Jamie.Dale

	Merging static analysis fixes from 4.19

Change 3879305 by Jamie.Dale

	Improved the processing of py files from exec commands

	The old logic used to just test if the entire command was a .py file. The new logic extracts out the first token and sees if that's a .py file, and if it is, treats the remaining data as extra arguments.

Change 3879306 by Jamie.Dale

	Added a minimal commandlet for invoking Python scripts

Change 3881631 by Jamie.Dale

	Added basic RTTI to Python meta-data types

Change 3885384 by Jamie.Dale

	[Python] Prevent glue code using reserved names

Change 3888957 by Patrick.Boutot

	In MediaPlayer, only create a PlayerFacade & Playlist when it's not a ClassDefaultObject.
	The MediaPlayerFacade is a MediaTickable. That trigger the tick thread to be awake even if there is no Media playing.

Change 3888961 by Patrick.Boutot

	Fix FInterval::IsValid return type.

Change 3888980 by Patrick.Boutot

	Modification to Media and MediaAsset to support MediaSmith. The TInterval<int64> will be changed into TTinterval<FTimespan> UEENT-947. MediaSampleQueue's critical section will be change into an atomic operation UEENT-948.

Change 3889165 by Patrick.Boutot

	Fix build. Missing include for Timespan. Introduce with CL 3888980.

Change 3889261 by Jamie.Dale

	[Python] Fixing some more name conflicts in generated code

Change 3889504 by Darren.Pegg

	TTinterval use it own traits. Create a Interval traits for Timespan.
	#jira UEENT-947

Change 3899669 by Jamie.Dale

	Fixed Functions sometimes being exposed to Python as if they were Structs

Change 3900692 by Jamie.Dale

	Removed some boilerplate associated with wrapping a basic type to Python

	You can now derive from TPyWrapperBasic to wrap a type that is simply a value copied into Python (see FPyWrapperName and FPyWrapperText for an example)

Change 3901066 by conan.reis

	UE4 editor script bindings (Cobra) and helper functions for version control
	- exposed SourceControl class with common source control methods and associated SourceControlState structure
	- commands have smart file strings that can convert from any of fully qualified path, relative path, long package name, asset path or export text path (often stored on clipboard)
	- commands store any errors in a shared error text object which is optionally printed to the error log
	- renamed some calls across the UE4 codebase to USourceControlHelpers::CheckOutOrAddFile() from USourceControlHelpers::CheckOutFile()
	- included Python test script for source control commands including that auto-creates test files as needed and passes various types of files to test as command line arguments. Any unexpected results displays error messages.

Change 3901388 by Jamie.Dale

	Minimal Slate hooks for Python

Change 3901456 by Jamie.Dale

	Added missing file

Change 3901549 by Jamie.Dale

	Removing some more Windows defines that were causing build issues

Change 3904518 by conan.reis

	Source Control
	- ensured that "check if modified" flag is set whenver getting source control state in USourceControlHelpers::QueryFileState() which was needed when using Perforce source control provider

Change 3905612 by Francis.Hurteau

	Optimize RemoveDuplicates somewhat using a TSet
	#jira UEENT-217

Change 3912626 by Jamie.Dale

	Fixed ShouldExcludeDerivedClasses option not working

	RecursiveClassesExclusionSet requires a base ClassNames entry to operate on when filtering.

Change 3917739 by Jamie.Dale

	Output Log suggestions list is now clamped to the work area width of the monitor that hosts the widget

Change 3917744 by Jamie.Dale

	Changed generated code to reference the UProperty and UFunction directly, rather than constantly look them up by name

	Names were originally used because UHT couldn't access the objects when it registered the glue code, but now that we generate at runtime via reflection, we already have the relevant objects available, and caching them the glue structs helps performance at both generation time and runtime.

Change 3918832 by Jamie.Dale

	Removed field iteration from Python function calls

	We now cache the input and output parameters for all function calls (methods, get/set, and delegates) and use this rather than iterate the struct fields.

Change 3920648 by Patrick.Boutot

	Remove the bottom right part of the windows border of the grabbed frame when in the editor. Tested in the standalone, windowed and full screen.
	Add option to request a FlushOnDraw on the viewport. Flushing in SDI output flow decreases the performance by ~10ms. SDI output is synchronized and the engine tick follows that synchronization.

Change 3921396 by Jamie.Dale

	Split up the generated type data to correspond to the type being wrapped

	A lot of types can just use the minimal set, but classes and structs have some extra data.

Change 3921619 by conan.reis

	- add delegate to FSourceControlWindows::ChoosePackagesToCheckin() that gives info for result, result description, files added, files checked in and flag indicating whether files were checked out again.
	- also added result info to FSourceControlWindows::PromptForCheckin()

	#jira UE-55255

Change 3921624 by conan.reis

	Removed Source Control common files from pre compiled header
	- main changes are in UnrealEdPrivatePCH.h, UnrealEdSharedPCH.h, SouceControlWindows.h and the added SouceControlWindows.cpp
	- remaining files have includes changed to accomodate

Change 3921958 by conan.reis

	Fix attempt for incude file dependency needed by some build configurations (likely PCH disabled) caused by CL3921619

Change 3922740 by conan.reis

	Included SourceControlOperations.h and SourceControlHelpers.h back in ISourceControlProvider.h though it does not need them since other files that were including ISourceControlProvider.h have come to expect their inclusion.
	They were previously removed in CL3921624

Change 3923375 by Jamie.Dale

	Added optimized FString <-> icu::UnicodeString conversion for platforms using UTF-16 native strings

Change 3926547 by Jamie.Dale

	Added support for struct method "hoisting"

	This allows you to tag a helper function that takes a struct as its first argument with the ScriptMethod meta-data (optionally providing a new name) to "hoist" that helper function to be a method of the struct it operates on when wrapped for Python.

Change 3927050 by conan.reis

	Source control - ensured that  ISourceControlProvider::Execute(FConnect, EConcurrency, FSourceControlOperationComplete) delegate is called on initial connection even if it fails immediately. Modified Perforce, Git and Subversion source control providers

	#JIRA UE-55256

Change 3929268 by conan.reis

	- fixed case in Perforce source control code where the server available flag was set even when the server was not successfully connected
	- removed Perforce error message about file folders outside of the workspace client mappings
	- clarified comments for ISourceControlProvider::IsEnabled() and ISourceControlModule::IsEnabled()

	#JIRA UE-55254

Change 3931024 by Rex.Hill

	Expose FBX and Texture import to python

Change 3931273 by Rex.Hill

	Hide re-import slate notification pop-up during python automated asset import

Change 3931368 by Jamie.Dale

	Stopped bools coercing to numeric types in Python nativization

Change 3931374 by Jamie.Dale

	Added support for struct math operator "hoisting"

	This allows you to tag a helper function that takes a struct as its first argument with the ScriptMathOp meta-data (providing a potentially semi-colon separated list of operators to map to) to "hoist" that helper function to be a math operator of the struct it operates on when wrapped for Python.

Change 3932586 by Rex.Hill

	Removed file read into unused memory buffer during Fbx import

Change 3934308 by Jamie.Dale

	Added a public interface for the Python plugin

	Very basic, just lets you query if Python is compiled in, and lets you execute Python commands like you would via the Output Log.

Change 3935088 by conan.reis

	- Added info/warning and error message storage to all the source control operation structures so additional information can be made available.
	- Added ISourceControlOperation::GetResultInfo() which returns the modified control structures (mentioned above) with appended info/warning messages and error messages and implemented its use in all source control operations in Perforce, Git and Subversion.

	Avoid re-allocation of memory buffer holding file bytes during asset import

Change 3940596 by Rex.Hill

	#jira UE-55989 Optimize skeletal mesh import performance scaling

	Overlapping vertex check was O (N^2)

Change 3942629 by Rex.Hill

	#jira UE-55995 Read fbx file only once during import

	Fixes a memory leak of FbxScene and reduces wait time during import.

Change 3942884 by Rex.Hill

	Python asset import can now customize destination asset name

Change 3946278 by Jamie.Dale

	Added stricter conversion for math operator arguments

	PyConversion now returns FPyConversionResult rather than bool, which will tell you not only whether a conversion succeeded or failed, but also whether type coercion was applied during the conversion.

	This allows the operator stack evaluation to run a first pass looking for an exact argument match, before falling back to a coerced match if available. This allows operators to apply correctly to coerced types (eg, int vs float overloads).

Change 3948455 by Jamie.Dale

	Added generic Tick function to FPythonScriptPlugin

	This can also handle init logic for after the engine is fully initialized

Change 3948888 by Jamie.Dale

	Added settings for the Python plugin

	You can now define start-up scripts to execute once the engine is initialized, additional system paths for Python, and whether you want to enable developer mode (which will enable things like deprecation warnings).

	Fixed doc string generation for a function with multiple output paramters and no return value

Change 3954279 by Jamie.Dale

Change 3941865 by Mark.Satterthwaite

	Fix the incorrect landscape rendering and the incorrect render-to-texture from blueprint bugs with MetalRHI.

	- Track outstanding AsyncCopyBufferFromBufferToBuffer operations to identify attempts to modify overlapping ranges within the same prologue command-buffer. This doesn't work and requires that we break the current render-pass and issue on the current command-buffer. A log warning will be emitted  when this occurs.

	- Don't attempt to alias private memory buffers the moment they are released from the RHI resource because that can lead to incorrect sharing of the memory when used by AsyncCopyBufferFromBufferToBuffer.

	#jira UE-56021

Change 3940993 by Marc.Audy

	Do not return the last column if the specified column does not exist.

	#jira UE-53492

Change 3938305 by Mark.Satterthwaite

	For whatever reason moving the buffer initialisation into the prologue command buffer doesn't work - this make absolutely no sense to me. I suspect that this is *merely* moving a render pass boundary around somewhere and forcing raster-state to be reapplied.

	#jira UE-56005

	#jira UE-55957

Change 3934892 by Mark.Satterthwaite

	In MetalRHI treat BUF_Volatile buffers as Shared or Managed memory in all circumstances so that multiple updates within a render pass are respected even though this will hurt CPU performance. This fixes GPU particles on macOS. Also push initialisation upload into the async. command buffer to avoid it overwriting a later Lock/Unlock! Only read-back and copy-buffer operations should be on the 'current' command buffer as they need to be inline with all outstanding commands.

Change 3920519 by Phillip.Kavan

	Fix a regression in which elements would not be initialized when constructing the value assignment for UDS-typed container members in nativized Blueprint C++ code.

	Change summary:
	- Modified FEmitDefaultValueHelper::InnerGenerate() to remove UDS from the list of special cases that avoid calling InitializeStruct() as part of new element construction. Previously the conversion code assumed the compiler would perform value initialization of a nameless temporary, but that is no longer valid in 4.19, as UDS types have been changed to function more like native structs, and as such all converted UDS types will now emit an explicit default ctor which is now used to assign defaults that differ from the zero-initialized value.

	MediaCompositing: Implemented media track for Sequencer

	Copied from Dev-Sequencer

	#jira UE-53974

Change 3920004 by Jack.Porter

	Disable Manual Vertex Fetch SRV creation when MVF is disabled.

	Made a single RHISupportsManualVertexFetch(EShaderPlatform) to control whether to use MVF. The Shader Platform (or alternatively, feature level) is the only thing that can decide whether or not to use MVF because we need to know when we compile the shaders if we're going to do MVF or not. Checking GSupportsResourceView at runtime is useless because the shaders can't change and so if GSupportsResourceView can ever be false for a platform, the shaders need to have been built without it.

	Creating SRVs without using them on mobile is not harmless because several devices don't support formats that are needed.

Change 3919069 by Aaron.McLeran

	#jira UE-55718 Fix for playback progress.

	Added an accessor to get the transform of the face mesh or a face mesh component

	#jira: UE-55531

Change 3915967 by Mark.Satterthwaite

	Place buffer updates into the prologue command-buffer in MetalRHI to avoid breaking the current command-encoder. This improves performance, though the semantics of Metal now differ subtly to other RHI implementations as the buffer updates happen prior to the SetRenderTargets call in the GPU's view of the world.

	Make compilation manager's skeleton class layout better match the old compilation path's skeleton class layout, fixes a crash when renaming blueprint functions

	#jira UE-55592

Change 3915250 by JeanLuc.Corenthin

	Can't add C++ code to Enterprise projects (when enterprise is installed)

	Root cause: When compiling a C++ project, Datasmith modules are included in the build process (with the wrong path)

	Fix:
	- Added two more Enterprise directories, Plugins and Intermediate, to the Enterprise directories to check against
	- Build the correct path for the Datasmith modules and plugins in FindOrCreateModuleByName. Added check to see if module is under one of the Enterprise directories.
	- Added modules to list of precompiled modeules in UEBuildTargets.AddPrecompiledModules if Engine and Enterprise are 'installed and the module is under Enterprise.

	#jira UEENT-1032

Change 3915240 by Ben.Marsh

	Reduce editor startup times by ~15s on Windows.

	Platform loading code recursively scans every module for dependent DLL modules to load first. Change to make it early-out as soon as it encounters a module which is already in memory (via a call to GetModuleHandle() from ResolveMissingLibraryImportsRecursive). Also use a TSet<> to store set of visited modules rather than an Array.

	Now spends <0.1s total in this function on editor startup.

	(Change looks larger than it is due to moving functions out of WindowsPlatformProcess.h to avoid introducing TSet dependency into this header).

	#jira UE-55642

Change 3914803 by Gil.Gribb

	UE4 - Removed memory track from the lock free list links. This is not safe and will sometimes assert in debug.

	#jira UE-49600

Change 3914616 by zak.parrish

	Adding Calibrate button #jira none

Change 3914599 by Andrew.Rodham

	Sequencer: Sequence template source signatures are now also compared to catch the case where a sub-sequence asset has been saved but not modified

	  - The following sequence of events exposes this issue:
	    - Create a master sequence with a single shot that spawns a cube
	    - Add this sequence to a level and set it to auto-play
	    - Save everything and restart
	    - Resave just the inner shot asset without opening it
	    - PIE
	    - The inner shot never spawns its cube because its template was wiped on save, but its signature never changed. Since the master sequence previously didn't check the template source signature, it ends up trying to evaluate an empty template.

	Fix editor-only default subobjects inherited from a native C++ parent class not being handled correctly during nativized Blueprint class ctor generation.

	Change summary:
	- Modified FEmitDefaultValueHelper::HandleSpecialTypes() to skip editor-only checks for instanced default subobjects. These will have already been created by a native parent class.
	- Modified FEmitDefaultValueHelper::HandleInstancedSubobject() to assert before creating a "dummy" component in place of an editor-only instance if we're not supposed to be creating it.

	 - The SubSections array is leaked when the memstack is popped.
	 - Fix replaces the TArray with a TStaticArray of max size MAX_SUBSECTION_COUNT (which is 4).

	(Merging as edit CL 3911422 from //Fortnite/Release-3.1/... to //UE4/Release-4.19/...)

	This is a particular case of UE-52328 iOS reporting crash on application exit: SPRINGBOARD, process-exit watchdog transgression

	Found several issues on iOS if the game is forced closed when the startup movie is playing and "Wait for movies to complete" is enabled in Project Settings

	- the game thread is waiting for the movie to complete on game shutdown - more that 5 sec

	- crash on FDefaultGameMoviePlayer::Shutdown if the above is fixed

	[CONSOLE] [^] Added RHI Command List Enqueue Lambda method (merging as edit CL 3879722 from //Fortnite/Main to //UE4/Release-4.19)

	 - Can be used to enqueue arbitrary tasks on the RHI thread from the render thread (similar to how EURC works for GT -> RT tasks), without having to write lots of bolierplate FRHICommand functor classes.
	 - The first overload of EnqueueLambda method will check Bypass() to determine if it should run the lambda immediately or defer to the RHI thread.
	 - This can be overriden via the 2nd overload if you need to check additional things such as IsRunningRHIInSeparateThread.
	 - The function returns true if the lambda was enqueued and deferred to the RHI thread, otherwise false. This can be used to optionally add RHIThreadFences for unlock commands etc.

	Fix/workaround for inconsistent preprocessor definitions for NVAftermath that result in FD3D11DynamicRHI class layout mismatch. NVAftermath support is now enabled by default for Win64.

	NVAftermath is declared as a private dependency in D3D11RHI. It does not automatically propagate to modules that explicitly include private RHI headers (OculusHMD, OSVR, OSVRInput). This results in NV_AFTERMATH being defined while compiling RHI module and not defined when compiling other modules, causing memory corruption at runtime.

	The long-term solution for this and similar issues requires some mechanism for adding transitive module dependencies, so that anyone that depends on D3D11RHI module would automatically also get the NVAftermath. Additionally, private headers should *never* be included directly by external modules.

	The short-term solution is to explicitly add NVAftermath dependency to OculusHMD, OSVR and OSVRInput.

	Additionally, NV_AFTERMATH is no longer forced by D3D11RHIPrivate.h when it's not defined. This allows catching this kind of mismatch in the future through a compiler warning (C4668).

	Sequencer: Fixed overlapping ranges being inserted into the evaluation field during compilation

	  - The issue was that track segments that had been combined with adjacent segments (due to them being identical) would potentially cause a subsequently compiled frame to overlap with a range that had already been inserted into the evaluation field.
	  - The insertion code previously asserted that only minor overlaps were catered for (due to fp rounding errors) and assumed that a supplied range could not entirely contain any other range in the field.
	  - The solution is to supply the insertion time along with the range to know exactly where the data should live in the field, and crop the range to the maximum allowable space between adjacent ranges.

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

	Added CORE_API to FArchiveFromStructuredArchive

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.

	Also rename FStructuredArchive::TryEnterSlot() to TryEnterField().

	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.

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.
