Preview 22 (draft)

	== Preview ~~19: Changes since Preview 18~~ ==		== Preview 22 (draft) ==

	~~Thank~~ you ~~all for your patience!~~ The ~~end~~ of the ~~semester~~ is ~~always~~ a ~~super busy period so~~ this ~~release took~~ a ~~while longer than expected~~. Special thanks to YoYoBatty for contributing several of the bug fixes. Changes since preview 18 include:		A small set of high-impact fixes and improvements:
			* We fixed a bug that crashed the game on maps with invalid MyLevel code (e.g., VCTF-ThermalPlayGround-2)
			* You can now use the Core.Object.AllPackageFiles(out string FileName, optional string FileExt, optional string Prefix) iterator to iterate through all package files with the given prefix or extension
			* We added the "FILECACHE REFRESH" and "FILECACHE LIST" console commands
			* The webadmin now has a button that refreshes the file cache. This is useful if, e.g., you've uploaded a new map while the server was running
			* The UWeb.WebRequest.Dump and UWeb.WebResponse.Dump functions should now, once again, work as expected
			* The editor and UCC will now print a more detailed error message when they fail to save a package
			* ALAudio will now play 2D sounds without HRTF and 3D sounds with HRTF by default. You can override this behavior by setting ForceHRTF to True or False in the [ALAudio.ALAudioSubsystem] section of the ini (this is still being worked on)

			== Preview 21 ==

			Another really small update. This fixes a problem in the UnrealScript compiler. It also fixes an issue that truncated crash logs.

			== Preview 20 ==

			This preview contains a few small bug fixes and improvements.
			* AntiDrv and D3D11Drv now support two fullscreen scaling modes:
			1. Stretch (default): stretches the rendered image to fill your entire screen but does not preserve the aspect ratio
			2. Aspect ratio: stretches the rendered image as much as possible while preserving the aspect ratio

			You can enable aspect ratio scaling by adding the ScalingMode=AspectRatio setting to the [D3D11Drv.D3D11RenderDevice] or [AntiDrv.AntiRenderDevice] sections of your game ini. We will probably also make this setting configurable in the menu soon.
			* AntiDrv, D3D11Drv, and OpenGLDrv now apply the same brightness, contrast, and gamma correction to screenshots as they do to the game
			* We fixed a bug that prevented some maps from loading
			* The mutant game mode now registers kills correctly (https://github.com/OldUnreal/UT2004Patches/issues/497)

			== Preview 19 ==

			Special thanks to YoYoBatty for contributing several of the bug fixes. Changes since preview 18 include:

	* We fixed a regression bug that made it impossible to (re)load certain maps in UnrealEd		* We fixed a regression bug that made it impossible to (re)load certain maps in UnrealEd

	Another unwelcome surprise came up: our exception handling mechanism had a bug that made the game quit rather than show a crash box when encountering a fatal exception. We fixed the bug so we can now hopefully get to the bottom of some of the crash bugs we haven't resolved yet.
