- Linkers are no longer UObjects. Renamed ULinker, ULinkerLoad and ULinkerSave to FLinker, FLinkerLoad, FLinkerSave respectively
- Linkers are now associated with their UPackages
- Linker version is now stored in UPackages
- Async loading is now performed on a separate thread (if platform supports it and only in cooked builds), with the exception of PostLoad which is still done on the game thread
- Added UObject::IsPostLoadThreadSafe() function to determine if PostLoad is thread safe and can be executed on the async loading thread (defaults to false)
- UObject creation is now thread safe and can be performed on any thread
- Move many of the linker/UObject globals into FUObjectThreadContext (TLS)
- GetAsyncLoadPercentage() now takes PostLoad into account
- More async loading stats
- Added AtomicallySetFlags/ClearFlags to UObject
- Made FModuleManager thread safe.
- Added FGCScopeGuard as means of preventing GC from executing from non-game thread
- It's possible to disable async loading thread through ini settings.
- Cancelling async loading will now also trigger GC
- Implemented a basic version of async streaming priorities.

Core - Added AtomicallySetFlags/ClearFlags to UObject, added a comment to ThisThreadAtomicallyClearedRFUnreachable
[CL 2498249 by Robert Manuszewski in Main branch]
Fixed failed C++ hot reload not displaying an error to the user (UE-8241)
- Also added slightly better progress reporting to hot reload when adding code to a project
[CL 2419709 by Ben Marsh in Main branch]
- CDO property values that have changed after hot-reload will now be propagated to the existing instances
- Adding code to a non-code project will no longer require restarting the editor to be able to work with new code (the new module will automatically be compiled and loaded)
[CL 2385307 by Robert Manuszewski 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.

There is now a consistent set of methods for module loading, unloading and lookup that all behave in the same expected way.
- renamed GetModuleInterface to GetModule and made it not assert
- removed GetModuleInterfaceRef
- namespace enums to enum classes, NULL to nullptr
- moved important public methods to the top, so they're easier to discover
- added missing & improved existing documentation
- cleaned up existing use cases
[CL 2109936 by Max Preussner in Main branch]
Other Updates:
- The WidgetReflector is now in its own module as well. It will be converted to a plug-in later.
- The Public API of both Slate and SlateCore has largely been reorganized for better discoverabilty. More cleanup work is needed.
- Added a lot of missing API documentation and fixed existing ones. More and better documentation is needed.
- Removed dead code, fixed a couple things I stubled upon, and conformed to coding guidelines (NULL vs nullptr, line breaks, etc.)
Upgrade Notes:
- The Slate Remote Server is currently disabled - will be re-enabled shortly!
- If your module previously had a module dependency to 'Slate', it now also needs a PrivateModuleDependency to 'SlateCore' in its Build.cs file.
- If your module exposes in any of its Public header files types that are now declared in SlateCore, it needs a PublicModuleDependency to 'SlateCore'
- The ToolTip property type on SWidget has changed from SToolTip to IToolTip; change local variables to TSharedPtr<IToolTip> instead of TSharedPtr<SToolTip> where needed
- IToolTip is not a widget. If you need access to the actual widget that represents the tool tip, use IToolTip::AsWidget(); If you need access to the tool tip's content, use IToolTip::GetContentWidget()
Troubleshooting:
- After syncing to this changelist you may have to clean your /Engine/Intermediate/Build/ directory and rebuild your entire project
- If in your project you are getting linker errors for unresolved types that are now declared in SlateCore, you may be missing a dependency to 'SlateCore'
- If in the Engine code you are getting linker errors for unresolved types that are now declared in SlateCore, you may need to rebuild the entire Engine
