*	Halo: Highlight selected face	RealBadAngel	2016-11-12
| | | | |	This is a slightly modified and cleaned up version of #3774 by RealBadAngel. By sofar: Remove color change (just make it lighter) and some minor cleanups.
*	Textures: New 'smoke puff' texture from TNT mod	paramat	2016-10-04
|
*	Main menu, lua_api.txt: Fix mod/texture pack screenshot size issues	Wuzzy	2016-07-27
| | | | | |	Recommend mod screenshot size in lua_api.txt Adjust displayed screenshot size of texture packs Document texture pack files in lua_api.txt
*	Textures: Replace menu background fallback dirt_bg.png with empty sky texture	paramat	2016-04-21
|
*	Mainmenu: Unify favorite servers with main serverlist	kilbith	2016-04-20
|
*	Minimap: revert change from RGBA to Indexed	Auke Kok	2016-04-11
| | | | | |	@kilbith spotted correctly that I had accidentally removed the "soft" edging on the minimap overlay by converting it from RGBA to Indexed, which killed the transparent pixels on the edging.
*	Minimap: "North" indicator arrow for circle minimap	Auke Kok	2016-04-08
| | | | | | | | | |	Related: #3730 This adds a simple, and small "North" indicator to the circular minimap. The indicator is in a classical triangle-like arrow with a little bit of shading to accentuate the shape and give it a little bit depth. The indicator is stuck exactly at the edge as far outwards as possible, and is not too intrusive but still easy enough to spot.
*	Update menu header image	Jean-Patrick Guerrero	2016-03-25
|
*	Resize object_marker_red.png to 16x16	ShadowNinja	2016-02-28
| | | |	Having a non-power-of-two image broke the Android app.

*	Add support for Android 2.3+	sapier	2014-06-29
| | | | | | | | | | | | |	There have been plenty of ppl involved in creating this version. I don't wanna mention names as I'm sure I'd forget someone so I just tell where help has been done: - The partial android versions done by various ppl - Testing on different android devices - reviewing code (especially the in core changes) - testing controls - reviewing texts A big thank you to everyone helping this to be completed!
