MAJOR FEATURES + CHANGES
==========================
Change 3209340 on 2016/11/23 by Ben.Marsh
Convert UE4 codebase to an "include what you use" model - where every header just includes the dependencies it needs, rather than every source file including large monolithic headers like Engine.h and UnrealEd.h.
Measured full rebuild times around 2x faster using XGE on Windows, and improvements of 25% or more for incremental builds and full rebuilds on most other platforms.
* Every header now includes everything it needs to compile.
* There's a CoreMinimal.h header that gets you a set of ubiquitous types from Core (eg. FString, FName, TArray, FVector, etc...). Most headers now include this first.
* There's a CoreTypes.h header that sets up primitive UE4 types and build macros (int32, PLATFORM_WIN64, etc...). All headers in Core include this first, as does CoreMinimal.h.
* Every .cpp file includes its matching .h file first.
* This helps validate that each header is including everything it needs to compile.
* No engine code includes a monolithic header such as Engine.h or UnrealEd.h any more.
* You will get a warning if you try to include one of these from the engine. They still exist for compatibility with game projects and do not produce warnings when included there.
* There have only been minor changes to our internal games down to accommodate these changes. The intent is for this to be as seamless as possible.
* No engine code explicitly includes a precompiled header any more.
* We still use PCHs, but they're force-included on the compiler command line by UnrealBuildTool instead. This lets us tune what they contain without breaking any existing include dependencies.
* PCHs are generated by a tool to get a statistical amount of coverage for the source files using it, and I've seeded the new shared PCHs to contain any header included by > 15% of source files.
Tool used to generate this transform is at Engine\Source\Programs\IncludeTool.
[CL 3209342 by Ben Marsh in Main branch]
Includes the following engine-level changes (among others; biggest change is enabling world assets by default):
CL 2252857
added dynamic allocations for path finding, removed hardcoded limit of 128 polys in path corridor
CL 2256142
Added support for native arrays in JSON object converter.
- Permissive in treating arrays of size 1 and scalars as equivalent
- Excess elements in JSON are ignored. Serialization succeeds but a warning is logged
CL 2256073
Fixed a bug in ARecastNavMesh::BatchRaycast resulting in NaN hit locations
CL 2253797
#UE4 More aggressively setting RF_Public and RF_Standalone flags on maps and ensuring world names match package names. This is necessary because umaps are currently being managed outside of the content browser and it is causing a few issues. Also, packages containing maps now synthesize asset data when the package contains absolutely no asset data (probably because the UWorld in it was not RF_Public at the time it was saved due to a previous bug).
CL 2258142
#UE4 Added a GC during map load that reclaims memory allocated during load/init. This is needed to finish the load on low-memory devices in games that allocate more memory after load.
CL 2247003
Added homing to ProjectileMovementComponent
- Homing requires both a bool and a target component to be set, the strength is determined by a customizable variable
- Both homing and gravity are now applied in the new virtual function "CalculateAcceleration"
CL 2247249
Moved the homing modification to acceleration occur in a separate function specifically for homing
CL 2257043
- Guard net dormancy calls against executing on clients, based on thread with DaveR and JohnP; This particular case was the result of an intentionally client-authoritative actor calling the dormancy functions via inheritance
CL 2245629
#UE4 - fixed json TryGetNumber to round negatives appropriately
CL 2255312
#UE4 Enabling World Assets by default.
CL 2260956
Analytics ET now loads HTTP at StartupModule so the module will be available during ShutdownModule to flush events
CL 2245571
GenericTeamAgentInterface can now retrieve attitude of an agent towards a given actor #UE4
- Made PerceptionSystem's sight sense take advantage of that
CL 2246897
Fixed perception listeners not being removed from the PerceptionSystem on Owner's end play #UE4
- addresses TTP#343392
CL 2260634
added more debug data for NaN in crowd simulation
CL 2248387
Added possibility to debug multiple EQS queries with GameplayDebugger. #ue4
Fixed network replication from bandwidth point of view for data in GameplayDebugger. #ue4
CL 2253281
Added additional information to the visual logger for UBTCompositeNode::DoDecoratorsAllowExecution
- We now keep track of whether a decorator allows execution, in addition to the existing log for not allowing execution
CL 2255310
#UE4 The world browser module now listens to WorldAdded/WorldDestroyed events instead of WorldInit/WorldCleanup events. Worlds can be initialized without being the editor world and this handles that case.
CL 2258256
#UE4 Replacing the SOpenLevelDialog with a new generic SAssetDialog. This dialog will be used as a generic Open or Save As dialog for assets.
[CL 2266822 by Billy Bramer in Main branch]
Breaking changes include:
* Rename of GEditorModeTools -> GLevelEditorModeTools to signify that it applies only to the level editor modes
* Addition of FEditorModeRegistry, responsible for managing and creating new editor modes. Modes are no longer registered with an instance of the mode, instead with a mode factory that is able to create a new mode of that type.
* Editor modes now operate on FEditorViewportClients rather than FLevelEditorViewportClients
* Added ability to specify an FEditorModeTools when creating an FEditorViewport
Moved component vizualiser manager handling outside of individual editor modes, and into FLevelEditorViewportClient. This should make it easier to transplant in future.
This work addresses TTP#334640 - EDITOR: Investigate making editor modes a per-'editor' concept

[CL 2109245 by Andrew Rodham in Main branch]
Splitted World Browser views into three independent windows, each window can be summoned from a hierarchy view or details view toolbar
World composition can now be toggled through WorldSettings - bEnableWorldComposition. Once enabled persistent level will be treated as a world root. No more '?worldcompistion' parameter workarounds. 'Open World' command was removed, as levels saved with world composition enabled can be open through 'Open Level' command.
Added bEnableWorldOriginRebasing parameter to WorldSettings, which contols whether world origin shifting should be used
