Newly installed versions of the engine will now attempt to copy the project-agnostic config settings from a previous engine installation. This happens by way of a versioned manifest that copies old versions when the manifest does not exist, or is a different version. This code path is benign for non-installed versions of the engine (or FPaths::ShouldSaveToUserDir() is false).
EditorGameAgnosticSettings and EditorUserSettings ini paths have been renamed to EditorSettings and EditorPerProjectUserSettings respectively to better convey their purpose. In general, most settings should be saved in EditorSettings (project-agnostic) so that they apply regardless of which project is open. We have some way to go migrating existing settings for this to be the case, however.
Some previously per-project configuration files are now project-agnostic (such as Editor.ini, EditorKeyBindings.ini, and EditorLayout.ini)
GEditor->Access...Settings and GEditor->Get...Settings have been removed in favor of direct access of the CDO through GetMutableDefault<> and GetDefault<> respectively. Global config ini filenames that are not set up are now neither loaded nor saved on build machines, to handle the problem of indeterminate state more generically.
This addresses UETOOL-270 (Most editor preferences should be project-agnostic)
[CL 2517558 by Andrew Rodham in Main branch]
- 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.

Known minor bug: If multiple windows are open with pulses animating, only the one that is given the "dismiss all" command will stop animating. The others will continue until their windows are closed and reopened, or they are dismissed individually.

Rob asked me to back out GENERATED_*_BODY -> GENERATED_BODY change for now until the "_Validate and _Implementation auto-generation" discussion is over.

While the asset registry is loading we need to refresh tutorials as this is the only mechanism by which they are picked up by the browser.

This needs to use a seperate path now so we cant rely on the 'closed' event firing.
AN-93 - Tutorial Event Not Sending?
[CL 2468643 by Thomas Sarkanen in Main branch]
Always remind users about tutorials until they complete the tutorial or explicitly dismiss it (UE-9550)
- Previously, even opening a tutorial once would prevent the reminder beacon for that tutorial to show again, ever.
- Now, the beacon will be hidden for the remainder of that editor session and reappear the next time, unless the user completed the tutorial
- The user can also right click on the beacon and choose to "Don't Remind Me Again" which will prevent it from appearing in the future for that specific tutorial (no change in behavior)
