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)

#jira UE-9085 - new project browser window clipping
[CL 2511581 by Richard TalbotWatkin 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.

Stopped the "Compiling C++ Code" message in the editor MainFrame always having a cancel button
FModuleCompilerStartedEvent now passes a bool to say whether the hot-reload/compile operation is being run async, or whether it's blocking. We now only show the cancel button for async compiles, as the UI is otherwise blocked waiting for the compile to finish.
Added a bWaitForCompletion input parameter to DoHotReloadFromEditor. This mirrors the RebindPackages API that DoHotReloadFromEditor internally calls, and prevents UPackFactory needing to perform a manual tick.

UETOOL-213 - Minimize Slate FString -> FText conversion (remove SLATE_TEXT_ATTRIBUTE)
This fixes any editor/engine specific code that was passing text to Slate as FString rather than FText.
[CL 2399803 by Jamie Dale 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.

#ttp 345522: HotReload: Should not try to link DLLs when target is up to date
#change Added code to handle up-to-date state of modules in hot-reload code.
#change Added ECompilationResult::UpToDate and ECompilationResult::Canceled, ECompilationResult::Failed()
#change UBT: added -canskiplink command line param and support for skipping link actions when there was nothing to compile
#change extended the duration of re-compile notifications (TTP# 346604 NUXF-246 Hot compile fail message fades)
#change Added 'Compile Canceled' notification (instead of 'Compile Failed')

* Categorized templates into Blueprint/C++ templates and organized them into tabs
* New categories can be specified in the templatedefs.ini file of a template project using a Category tag:
Category=NewCategory
* New category types can be registered with a proper description and icon in code through FGameProjectGenerationModule::RegisterTemplateCategory.
* Added preview images to templates
* Generally tidied the UI
This addresses TTP#321302 - EDITOR: Project Browser: Reduce Thumbnail size of Templates

This is currently needed for Linux where SourceControl is expected to work headless and thus does not normally depend on Slate. Should be solved differently.

TTP# 338363 - When I relaunch the editor it reopens the items in the wrong place.
IÆve added a "DockedToolkit" tab which resides next to the "LevelEditor" tab. This is used for two purposes; firstly, it can be used to identify asset editors that have been dragged into the MainFrame, and secondly, it's used as a marker (akin to the "StandaloneToolkit" tab) to restore the asset editor to the correct place.
When an asset editor is closed, an entry is added to the GEditorUserSettingsIni file so that FAssetEditorToolkit::InitAssetEditor can restore the asset editor to either the "DockedToolkit" or "StandaloneToolkit" area.

- Game live streaming
- Allows general support for live internet streaming of game video and audio
- Web cam video feed can be overlaid onto game viewports automatically
- New 'Broadcast' Blueprint function library allows you to easily start broadcasting from your game
- New IGameLiveStreaming API that allows you to start broadcasting through C++
