- 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.
