MAJOR FEATURES & CHANGES
============================
Change 3494741 by Steve.Robb
Generated code size savings.
#jira UE-43048
Change 3495484 by Steve.Robb
Fix for generated indices of static arrays when saving configs.
Change 3497926 by Robert.Manuszewski
Removed FPackageFileSummary's CompressedChunks array as it was no longer being used by anything.
Change 3498077 by Robert.Manuszewski
Only use the recursion guard in async loading code when the event driven loader is enabled.
Change 3498112 by Ben.Marsh
UBT: Respect the option to not create debug info in the Android toolchain. This option is already being respected by the compiler, but the linker adds debug info of its own.
Change 3500239 by Robert.Manuszewski
Made sure the Super Class token stream is also locked when assembling Class token stream with async loading thread enabled. This to to prevent race conditions when loading BP classes.
Change 3500395 by Steve.Robb
Extra codegen savings when not in hot reload.
Change 3501004 by Steve.Robb
EObjectFlags now have constexpr operators.
Change 3502079 by Ben.Marsh

Change 3504424 by Steve.Robb
New AllOf, AnyOf and NoneOf algorithms.
Change 3504712 by Ben.Marsh
UAT: Less spammy log and error output from UAT.
* Callstacks for AutomationExceptions are suppressed by default but still included in the log (the path to the log is noted in console output with the message from the exception).
* Add a mechanism for any exceptions to be caught and rethrown with additional lines of context (CommandUtils.AddContext()) that will be appended to the error output by UAT. Avoids decaying the exception type or masking the inner exception message while still adding additional information.
* AggregateExceptions resulting from exceptions on child threads are automatically unwrapped (full details are still appended to the log)
* Name of the calling function is not included in console output by default, but still included in the log.
Change 3504808 by Ben.Marsh
UAT: Suppress P4 output when running a recursive instance of UAT.
Change 3505044 by Steve.Robb
Code generation improved for TCppClassType code.
Change 3505485 by Ben.Marsh
Fix deterministic cooking issue; always use a pseudo-random number stream when compiling a module.
Change 3505699 by Ben.Marsh
Plugins: Store the bEnabledByDefault flag exactly as it was read from disk rather than collapsing it to an absolute value based on the default for the location it was read from. This allows loading/saving plugin descriptors without any knowledge of whether they are game or engine plugins.
Change 3506055 by Ben.Marsh
UAT: Add a class to apply a log indent for the lifetime of an object (ScopedLogIndent), and use it to apply an indent to MegaXGE/ParallelExecutor output.
Change 3507745 by Robert.Manuszewski
Moved FSimpleObjectReferenceCollectorArchive and FSimpleObjectReferenceCollectorArchive to be internal archives used only by FReferenceCollector so that they are constructed only once per GC task instead of potentially multiple times per GC (as was the case with UDataTables and BlueprintGeneratedClasses).
Change 3507911 by Ben.Marsh
Plugins: Minor changes to plugin descriptors.
* Add a distinct setting for an unspecified EnabledByDefault setting in plugin descriptors.
* Add a function to IPlugin to determine the effective EnabledByDefault setting, based on where the plugin was loaded from.
Change 3508669 by Ben.Marsh

Fix for mismatched stat categories in AudioMixer.
#jira UE-46129
Change 3509289 by Robert.Manuszewski
Custom Version Container will no longer be always constructed in FArchive constructor. This reduces the number of the Custom Version Container allocations considerably.
Change 3509294 by Robert.Manuszewski
UDataTable::AddReferencedObjects will no longer try to iterate over the RowMap if there's no UObject references in it.
Change 3509312 by Steve.Robb

PR #3707: Fixed UBT stack size (Contributed by gildor2)
Change 3511808 by Ben.Marsh
Optimize checks for whether the game project contains source code. Now stops as soon as the first file is found and ignores directories beginning with a '.' character (eg. .git)
#jira UE-46540
Change 3512017 by Ben.Marsh
Plugins: Deprecate the QueryStatusForAllPlugins() function; the same functionality is available via the IPlugin interface.
Change 3513935 by Steve.Robb
Reverted array iteration in FPropertyNode::PropagatePropertyChange as this is now covered in TProperty::InitializeValueInternal() as of CL# 3293477.
Change 3514142 by Steve.Robb
MemoryProfiler2 added to generated solution.
Change 3516463 by Ben.Marsh
Plugins: Create a manifest for each PAK file containing all the plugin descriptors in one place. Eliminates need to recurse through directories and read separate multiple files in serial at startup, and allows reading all plugin descriptors with one read. The "Mods" directory is excluded from the manifest, since these are intended to be installed separately by the user.
Change 3517860 by Ben.Marsh
PR #3727: FString Dereference Fixes (Contributed by jovisgCL)
Change 3517967 by Ben.Marsh

#jira UE-40421
Change 3520480 by Robert.Manuszewski
Improved assert message when the initial package read request was too small.
Change 3520590 by Graeme.Thornton
SignedArchiveReader optimizations
- Loads more stats
- Stop chunk cache worker from waking up continuously to poll for work. Only wake up when triggered by the archive reader
- Signed archive reader just yields when waiting for buffers to finish loading, rather than sleeping for some arbitrary amount of time
- Track the number of pending read requests in an atomic counter, to save having to lock the request queue to check for new entries
Change 3521023 by Graeme.Thornton
Remove spin from signed archive reader. Main thread waits on an event triggered by the chunk worker to indicate that new chunks are ready for processing

Move Linux SDL initialization into FLinuxPlatformApplicationMisc. Attempting to move functionality related to interactive applications (graphics, input, etc...) into a separate place, so it can ultimately be moved out of Core.
Change 3524741 by Ben.Marsh
Move PumpMessages() into FPlatformApplicationMisc.
Change 3525399 by Ben.Marsh
UGS: Use the default Perforce server port when opening P4V if there is not one set in the environment.
Change 3525743 by Ben.Marsh
UAT: Add a parameter to allow updating version files without updating Version.h, to allow faster link times on incremental builds.

EC: Include the clobber option on new workspaces, to allow overriding version files when syncing.
Change 3526453 by Ben.Marsh
UGS: Do not generate project files when syncing precompiled binaries.
Change 3527045 by Ben.Marsh
Fix hot reload generating import libraries without DLLs. Now that they are produced by separate actions by default, it was removing DLLs from the action graph due to the bSkipLinkingWhenNothingToCompile setting.
Change 3527420 by Ben.Marsh
UGS: Add additional search paths for UGS config files, and fix a few cosmetic issues (inability to display ampersands in tools menu, showing changelist -1 when running a tool without syncing).
Config files are now read from:
Engine/Programs/UnrealGameSync/UnrealGameSync.ini
Engine/Programs/UnrealGameSync/NotForLicensees/UnrealGameSync.ini
If a project is selected:
<ProjectDir>/Build/UnrealGameSync.ini
<ProjectDir>/Build/NotForLicensees/UnrealGameSync.ini
If the .uprojectdirs file is selected:
Engine/Programs/UnrealGameSync/DefaultProject.ini
Engine/Programs/UnrealGameSync/NotForLicensees/DefaultProject.ini
Change 3528063 by Ben.Marsh
Fix non-thread safe construction of FPluginManager singleton. Length of time spent in the constructor resulted in multiple instances being constructed at startup, making the time to enumerate plugins on slow media significantly worse.
Change 3528415 by Ben.Marsh

Fixed lazy object pointers not being updated for streaming sub-levels in PIE. Fixed lazy pointers returning object that is still being loaded which could lead to undefined behavior when client code started modifying the returned object.
#jira UE-44996
Change 3530241 by Ben.Marsh
UAT: Only pass -submit or -nosubmit to child instances of UAT if they were specified on the original command line. BuildCookRun uses this flag to determine whether to submit, rather than just whether to allow submitting, so we shouldn't pass an inferred value.
Change 3531377 by Ben.Marsh
Plugins: Allow plugins to specify a list of supported target platforms, which is propagated to any .uproject file that enables it.
This has several advantages over the per-module platform whitelist/blacklist:
* Platform-specific .uplugin files can now be excluded when staging other platforms. Previously, it was only possible to determine which platforms a plugin supports by reading the plugin descriptor itself. Now that information is copied into the .uproject file, so the runtime knows which plugins to ignore.
* References to dependent plugins from platform-specific plugins can now be eliminated.
* Plugins containing content can now be unambiguously disabled on a per-platform basis (having no modules for a platform does not confer that a plugin doesn't support that platform; now it is possible to specify supported platforms explicitly).
* The editor can load any plugins without having to whitelist supported editor host platforms.
UE4 targets which support loading plugins for target platforms can set TargetRules.bIncludePluginsForTargetPlatforms (true for the editor by default, false for any other target types). This defines the LOAD_PLUGINS_FOR_TARGET_PLATFORMS macro at runtime, which allows the plugin system to filter which plugins to look for at runtime.
Any .uproject file will be updated at startup to contain the list of supported platforms for each referenced plugin if necessary.

Change 3539775 by Ben.Marsh
Plugins: Various fixes to settings for enabling plugins.
* Fix crash on startup when trying to disable a missing plugin (was keeping pointers to elements in the project's plugin reference array, which may be modified if a plugin is disabled).
* Revert fix to set PluginDescriptor.bRequiresBuildPlatform = true by default. This was the originally intended behavior, but it was accidentally defaulted to false during serialization unless specified in the .uplugin file. Many plugins may rely on this behavior (they may not declare asset classes otherwise, for example, which could result in loss of data), so change the default value to false instead. Also fixes popups to disable platform-specific plugins if platform SDKs are not installed.
* Fix plugins which are referenced but do not exist not showing the appropriate prompt to disable them.
Change 3540788 by Ben.Marsh
UBT: Add support for declaring custom pre-build steps and post-build steps from .target.cs files. Similarly to the custom build steps configurable from .uproject and .uplugin files, these specify commands which will be executed by the host platform's shell before or after a build. The following variables are expanded within the list of commands before execution: $(EngineDir), $(ProjectDir), $(TargetName), $(TargetPlatform), $(TargetConfiguration), $(TargetType), $(ProjectFile).
Example usage:
public class UnrealPakTarget : TargetRules
{
public UnrealPakTarget(TargetInfo Target) : base(Target)
{
Type = TargetType.Program;
LinkType = TargetLinkType.Monolithic;
LaunchModuleName = "UnrealPak";
if(HostPlatform == UnrealTargetPlatform.Win64)
{
PreBuildSteps.Add("echo Before building:");
PreBuildSteps.Add("echo This is $(TargetName) $(TargetConfiguration) $(TargetPlatform)");
PostBuildSteps.Add("echo After building!");
PostBuildSteps.Add("echo This is $(TargetName) $(TargetConfiguration) $(TargetPlatform)");
}
}

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

Change 3209340 on 2016/11/23 by Ben.Marsh
Convert UE4 codebase to an "include what you use" model - where every header just includes the dependencies it needs, rather than every source file including large monolithic headers like Engine.h and UnrealEd.h.
Measured full rebuild times around 2x faster using XGE on Windows, and improvements of 25% or more for incremental builds and full rebuilds on most other platforms.
* Every header now includes everything it needs to compile.
* There's a CoreMinimal.h header that gets you a set of ubiquitous types from Core (eg. FString, FName, TArray, FVector, etc...). Most headers now include this first.
* There's a CoreTypes.h header that sets up primitive UE4 types and build macros (int32, PLATFORM_WIN64, etc...). All headers in Core include this first, as does CoreMinimal.h.
* Every .cpp file includes its matching .h file first.
* This helps validate that each header is including everything it needs to compile.
* No engine code includes a monolithic header such as Engine.h or UnrealEd.h any more.
* You will get a warning if you try to include one of these from the engine. They still exist for compatibility with game projects and do not produce warnings when included there.
* There have only been minor changes to our internal games down to accommodate these changes. The intent is for this to be as seamless as possible.
* No engine code explicitly includes a precompiled header any more.
* We still use PCHs, but they're force-included on the compiler command line by UnrealBuildTool instead. This lets us tune what they contain without breaking any existing include dependencies.
* PCHs are generated by a tool to get a statistical amount of coverage for the source files using it, and I've seeded the new shared PCHs to contain any header included by > 15% of source files.
Tool used to generate this transform is at Engine\Source\Programs\IncludeTool.

bug where the cine camera actor won't tick if you hook in event tick.

Messaging: API code & documentation modernization pass
Mostly removed shared pointer/ref typedefs as they prevent forward declarations and increase include complexity.
Change 3153824 on 2016/10/06 by Max.Preussner
Messaging: Renamed IConnectionBasedMessagingModule to ITcpMessagingModule and moved it into TcpMessaging
I recommend that we refactor this API. The dependency should be reversed, i.e. instead of AndroidDeviceDiscovery depending on the TcpMessaging plug-in module, the Engine should provide a central registry that device discovery
modules can notify, and that message transport plug-ins can register with and listen to OnConnectionAdded/Removed events etc. That way it supports an arbitrary number of transport plug-ins, and the Engine is not coupled to any of them. This
functionality is not necessarily related to messaging, and the Messaging API is transport agnostic anyway. I'll think about this some more.
Change 3153826 on 2016/10/06 by Max.Preussner
Messaging: Removed remaining typedefs in IMessageTracer to enable forward declaration and reduce include dependencies

Sequencer: Add ability to step to beginning and ends of sections/shots using the hotkeys: , and .
Change 3154788 on 2016/10/07 by Max.Chen
Sequencer: Fix offsets that created when moving multiple sections. The offsets were being created because section bounds were being generated for all sections except for the current section. Instead, they should be computed for all
sections except for any that aren't being moved.

Editor: Added support for detail customizations on root structs
- Also added the ability to add external struct data onto a detail category builder, and property type customization.
Change 3171752 on 2016/10/24 by Andrew.Rodham
Sequencer: Fixed spawnable ownership
- Spawnables are no longer destroyed when the cursor leaves the master playback range.
- Spawnable ownership now operates as it previously did before the evaluation rework.
- bIgnoreOwnershipInEditor has been removed since its existence was a work around for when we didn't evaluate sub sequences from the master sequence.
- FMovieSceneSequenceID is now a struct so that it can be used in array properties
- Meta data now exists for each segment of an evaluation field. Currently this only includes the sub sequence IDs that exist at that time, but it may be expanded to include all evaluation entities (tracks + sections) in future so
we don't have to calculate that at runtime.
Change 3171756 on 2016/10/24 by Andrew.Rodham
Sequencer: Added ability to trigger events with parameters
- It's now possible to supply an event payload on event track keys which are to be passed to a given event. The structure must match the signature of the event, or a warning will be emitted.
- Added a templated TGenericKeyArea, TKeyFrameManipulator and TCurveInterface that allow to generic manipulation of keyframe section data. In time we will port the other key areas over to this representation.
- This new architecture affords the common manipulation of time-based keyframes in a value-agnostic manner.

UETOOL-213 - Minimize Slate FString -> FText conversion (remove SLATE_TEXT_ATTRIBUTE)
This fixes any editor/engine specific code that was passing text to Slate as FString rather than FText.
[CL 2399803 by Jamie Dale in Main branch]
* Moved Slate.h into SlateBasics.h and began shifting less commonly used headers into SlateExtras.h.
* Slate.h now simply includes SlateBasics.h and SlateExtras.h.
* Slate.h includes a deprecated warning now to indicate that SlateBasics.h + specific includes should be used instead.
* Moved dozens of inlined functions using Slate widgets into .cpp files to avoid header dependencies.
* All code samples now include SlateBasics.h and SlateExtras.h so future shifts will not break most those projects, but not trigger the deprecation warning of including Slate.h.

[CL 2329610 by Wes Hunt in Main branch]
Please note that file comments had no purpose in nearly all cases and just added visual clutter. The two files that had meaningful file comments had their comments moved into the corresponding classes. There are still hundreds of file comments left in other files that will be removed over time.
Also cleaned up some random stuff along the way:
- relative paths to public headers within the same module are no longer necessary (automatically discovered by UBT now)
- header guards are deprecated, use #pragma once instead (all compilers support it now)
- space between multiple template brackets is no longer required (all compilers support >> now)
- NULL to nullptr, OVERRIDE to override
- spelling errors, whitespace, line breaks
