MAJOR FEATURES + CHANGES
==========================
Change 3121996 on 2016/09/12 by Ben.Marsh
Add support for Visual Studio 2017 (aka "15"; assuming consistent naming with other versions until final name is announced).
* Compiler, STL implementation and CRT are binary compatible with VS2015 (see https://blogs.msdn.microsoft.com/vcblog/2016/08/24/c1417-features-and-stl-fixes-in-vs-15-preview-4/), so no new third-party libraries needed so far. WindowsPlatform.GetVisualStudioCompilerVersionName() returns "2015" as a result.
* Default compiler for compiling and generating project files is still VS 2015 for now. Pass -2017 on the command line to GenerateProjectFiles.bat to generate VS2017 projects. Projects generated for VS2017 will use the 2017 compiler by default.
* Visual Studio source code accessor can talk to VS 2017 instances.
* Added a VS2017 configuration for UnrealVS, and added precompiled vsix package.
* Switched GetVSComnTools to check the SOFTWARE\Microsoft\VisualStudio\SxS\VS7 registry key rather than the individual product install registry key. "15" doesn't seem to have it's own "InstallDir" key, but this system seems to work for all versions of Visual Studio (including previous releases of VS Express).
* Removed ATL dependency from VisualStudioSourceCodeAccessor. It's not installed with VS by default any more, and is only used for a couple of smart pointer classes.
Tested running the editor and packaging TP_Flying for Win64. Packaging from the editor still defaults to using the 2015 compiler, so ConfigureToolchain() needs to be overriden from the .target.cs file if multiple Visual Studio versions are installed.
Change 3189363 on 2016/11/07 by Ben.Marsh
Consolidate functionality for determining the path to MSBuild.exe to use for compiling UE4 tools into a single batch file (GetMSBuildToolPath) and fix "Clean" not working on PS4 due to include/library paths being set to something by the Visual Studio environment.
Change 3210598 on 2016/11/27 by Ben.Marsh
UBT: Prevent the name of each file compiled being output twice on XboxOne. Compiler already outputs this string; the action doesn't need to.
Change 3210601 on 2016/11/27 by Ben.Marsh
PR #2967: Add silent version of switch game version (Contributed by EricLeeFriedman)
Change 3210602 on 2016/11/27 by Ben.Marsh
PR #2964: GitDependencies shouldn't try to clean up working directory files that are excluded or ignored (Contributed by joelmcginnis)
Change 3210605 on 2016/11/27 by Ben.Marsh
UGS: Add a warning when syncing latest would remove changes that have been authored locally. Typically happens when working with precompiled binaries.
Change 3211656 on 2016/11/28 by Ben.Marsh
UBT: Move ModuleRules and TargetRules into their own file.
Change 3211797 on 2016/11/28 by Ben.Marsh
UBT: Remove utility functions from TargetRules for checking different classes of target types. Moving TargetRules to be data-only.
Change 3211833 on 2016/11/28 by Ben.Marsh
UBT: Remove overridable configuration name from target rules. This feature is not used anywhere.
Change 3211859 on 2016/11/28 by Ben.Marsh
UBT: Deprecate the GetGeneratedCodeVersion() callback in favor of a member variable instead.
Change 3211942 on 2016/11/28 by Ben.Marsh
UBT: Remove legacy code which tries to change the output paths for console binaries. Output paths for monolithic binaries are always in the project folder now.
Change 3215333 on 2016/11/30 by Ben.Marsh
UBT: Replace the GetSupportedPlatforms() callback on TargetRules with a SupportedPlatforms attribute. Since a TargetRules object can only be instantiated with an actual platform, it doesn't make sense for it to be an instance method.
Change 3215482 on 2016/11/30 by Ben.Marsh
UBT: Remove the GetSupportedConfigurations() callback on the TargetRules class. A configuration is required to construct a TargetRules instance, so it doesn't make sense to need to call an instance method to find out which configurations are supported.
Change 3215743 on 2016/11/30 by Ben.Marsh
UBT: Deprecate the TargetRules.ShouldCompileMonolithic() function: this function requires access to the global command line to operate correctly, which prevents creating target-specific instances, and does not use the platform/configuration passed into the TargetRules constructor.
Rather than being a callback, the LinkType field can now be set to TargetLinkType.Modular or TargetLinkType.Monolithic from the constructor as appropriate. The default value (TargetLinkType.Default) results in the default link type for the target type being used. Parsing of the command-line overrides is now done when building the TargetDescriptor.
Change 3215778 on 2016/11/30 by Ben.Marsh
UBT: Mark overrides of the TargetRules.GetModulesToPrecompile method as obsolete.
Change 3217681 on 2016/12/01 by Ben.Marsh
UAT: Prevent UE4Build deleting .modules files when running with the -Clean argument; these files are artifacts generated by UBT itself, not by the exported XGE script.
Change 3217723 on 2016/12/01 by Ben.Marsh
UBT: Run pre- and post-build steps for all plugins that are being built, not just those that are enabled.
Change 3217930 on 2016/12/01 by Ben.Marsh
UGS: Add a perforce settings window, allowing users to set optional values for tuning Perforce performance on unreliable connections.
Change 3218762 on 2016/12/02 by Ben.Marsh
Enable warnings whenever an undefined macro is used in a constant expression inside an #if or #elif directive, and fix existing violations.
Change 3219161 on 2016/12/02 by Ben.Marsh
Core: Use the directory containing the current module to derive the UE4 base directory, rather than the executable directory. Allows UE4 to be hosted by a process in a different directory.
Change 3219197 on 2016/12/02 by Ben.Marsh
Core: When loading a DLL from disk, convert any relative paths to absolute before calling LoadLibrary. The OS resolves these paths relative to the directory containing the process executable -- not the working directory -- so paths need to be absolute to allow UE4 to be hosted by a process elsewhere.
Change 3219209 on 2016/12/02 by Ben.Marsh
Replace some calls to LoadLibrary() with FPlatformProcess::GetDllHandle(). The UE4 function makes sure that relative paths are resolved relative to the correct base directory, which is important when the host executable is not in Engine/Binaries/Win64.
Change 3219610 on 2016/12/02 by Ben.Marsh
Add the -q (quiet) option to the Mac unzip command, since it's creating too much log output to be useful.
Change 3219731 on 2016/12/02 by Ben.Marsh
UBT: Add option to disable IWYU checks regarding the use of monolithic headers (Engine.h, UnrealEd.h, etc...) and including the matching header for a cpp file first. bEnforceIWYU can be set to false in UEBuildConfiguration or on a per-module basis in the module rules.
Change 3220796 on 2016/12/04 by Ben.Marsh
Remove PrepForUATPackageOrDeploy from the UEBuildDeploy base class. It never has to be accessed through the base class anyway.
Change 3220825 on 2016/12/04 by Ben.Marsh
UBT: Change all executors to derive from a common base class (ActionExecutor).
Change 3220834 on 2016/12/04 by Ben.Marsh
UBT: Remove the global CommandLineContains() function.
Change 3222706 on 2016/12/05 by Ben.Marsh
Merging CL 3221949 from //UE4/Release-4.14: Fixes to code analysis template causing problems with stock install of VS2017.
Change 3222712 on 2016/12/05 by Ben.Marsh
Merging CL 3222021 from //UE4/Release-4.14: Change detection of MSBuild.exe path to match GetMSBuildPath.bat
Change 3223628 on 2016/12/06 by Ben.Marsh
Merging CL 3223369 from 4.14 branch: Use the same logic as GetMsBuildPath.bat inside FDesktopPlatformBase to determine path to MSBuild.exe
Change 3223817 on 2016/12/06 by Ben.Marsh
Remove non-ANSI characters from source files. Compiler/P4 support is patchy for this, and we want to avoid failing prey to different codepages resulting in different interpretations of the source text.
Change 3224046 on 2016/12/06 by Ben.Marsh
Remove the need for the iOS/TVOS deployment instances to have an IOSPlatformContext instance. The only dependency between the two -- a call to GetRequiredCapabilities() -- is now implemented by querying the INI file for the supported architectures when neeeded.
Change 3224792 on 2016/12/07 by Ben.Marsh
UBT: Touch PCH wrapper files whenever the file they include is newer rather than writing the timestamp for the included file into it as a comment. Allows use of ccache and similar tools.
Change 3225212 on 2016/12/07 by Ben.Marsh
UBT: Move settings required for deployment into the UEBuildDeployTarget class, allowing them to be serialized to and from a file the intermediate directory without having to construct a phony UEBuildTarget to deploy.
Deployment is now performed by a method on UEBuildPlatform, rather than having to create a UEBuildPlatformContext and using that to create a UEBuildDeploy object.
The -prepfordeploy UBT invocation from UAT, previously done by the per-platform PostBuildTarget() callback when building with XGE, is replaced by running UBT with a path to the serialized UEBuildDeployTarget object, and can be done in a platform agnostic manner.
Change 3226310 on 2016/12/07 by Ben.Marsh
PR #3015: Fixes wrong VSC++ flags being passed for .c files (Contributed by badlogic)
Change 3228273 on 2016/12/08 by Ben.Marsh
Update copyright notices for QAGame.
Change 3229166 on 2016/12/09 by Ben.Marsh
UBT: Rewritten config file parser. No longer requires hard-coded list of sections to be parsed, but parses them on demand. Measured 2x faster read speeds (largely due to eliminating construction of temporary string objects when parsing each line, to trim whitespace and so on). Also includes an attribute-driven parser, which allows reading named config values for marked up fields in an object.
Change 3230601 on 2016/12/12 by Ben.Marsh
Swarm: Change Swarm AgentInterface to target .NET framework 4.5, to remove dependency on having 4.0 framework installed.
Change 3230737 on 2016/12/12 by Ben.Marsh
UAT: Stop UE4Build deriving from CommandUtils. Confusing pattern, and causes problems trying to access instance variables that are only set for build commands.
Change 3230751 on 2016/12/12 by Ben.Marsh
UAT: Move ParseParam*() functions which use the instanced parameter list from CommandUtils to BuildCommand, since that's the only thing that it's instanced for.
Change 3230804 on 2016/12/12 by Ben.Marsh
UBT: Add the IsPromotedBuild flag to Build.version, and only set the bFormalBuild flag in UBT if it's set. This allows UGS users to avoid having to compile separate RC files for each output binary.
Change 3230831 on 2016/12/12 by Ben.Marsh
UGS: Warn when trying to switch streams if files are checked out.
Change 3231281 on 2016/12/12 by Chad.Garyet
Fixing a bug where .modules files were getting put into receipts with their absolute path instead of their relative one
Change 3231496 on 2016/12/12 by Ben.Marsh
Disable code analysis in CrashReportProcess; causes warnings when compiled with VS2015.
Change 3231979 on 2016/12/12 by Ben.Marsh
UBT: Suppress LNK4221 when generating import libraries. This can happen often when generating import libraries separately to linking.
Change 3232619 on 2016/12/13 by Ben.Marsh
Fix "#pragma once in main file" errors on Mac, which are occurring in //UE4/Main.

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.

Ensure that warnings from Dynamic Compilation of build.cs files are propagated up to user when compiling in Visual Studio etc.
Change 2828335 on 2016/01/14 by Matthew.Griffin
Renaming AddThirdParty... functions to AddEngineThirdParty... so it's clear we're talking about third party libraries within the engine directory. This removes another couple of RunningRocket checks and uses the IsMonolithic property now.
Change 2831365 on 2016/01/16 by Ben.Marsh
Add a UAT command to remove any temp storage directories older than a specified length of time, and disable the GUBP node to do so when running with -NewEC. Better to set this up as a separate scheduled task for each temp storage folder we have, rather than run it as part of GUBP builds above a certain size.
Change 2832166 on 2016/01/18 by Ben.Marsh
Make INI file parsing much more tolerant to errors, because it prevents the build system from starting up. Now outputs warnings rather than throwing exceptions.
Change 2835725 on 2016/01/20 by Matthew.Griffin

Switch Linux staging check to see if required files exist until switched to using receipts
Always stage CrashReporter for Linux

Combined code doing very similar things for single games and rocket projects.
Removed check on whether to add client and server targets in Rocket as we don't distribute the .target.cs files.
Removed RunningRocket function and the code checking for -rocket on the command line
