• Added MODVERSION. (!1158 (merged))
• Added the PlayerCmd hook from Kart. This hook allows you modify the ticcmd locally, before it is sent to the server. (!1072 (merged))
• Added v.getStringColormap to hud hooks. (!1111 (merged))
• Added P_CeilingzAtPos. (!1164 (merged))
• Added CV_Set, CV_StealthSet and CV_AddValue to set cvars directly from Lua. (!1205 (merged))
• Added polyobject support. (!1140 (merged))
• Added gamestate. (!1229 (merged))

• player.lastlinehit and lastsidehit are now usable outside of climbing on walls, where they will represent the last wall collided with. (!1271 (merged))
• GameQuit hooks are now passed a boolean which tells if the hook is being called before the program closes. (!1276 (merged))
• skin.sprites (!1238 (merged))
• Added multitag library, which allows reading and manipulation of tags on mapthings, lines and sectors; also added tag iterator functions.(!1292 (merged))

Miscellaneous

• Attraction Shield's homing attack may now be chained. (!1109 (merged))
• Aliases can be autocompleted in the console. (!1113 (merged))
• Added a -splitscreen command line parameter. (!1175 (merged))
• Amy is no longer Toad. (!1183 (merged))
• The addfile command now supports adding multiple files. (!1176 (merged))
• A bunch of netvars are now saved to the config. Only the server will save a netvar's current value. Clients will save the value prior to joining the server. (!1179 (merged))
• The player will now smoothly slide across a sloped ceiling. (!1192 (merged))
• Replaced renderstats with perfstats. This shows timings for rendering, game logic and Lua ThinkFrame. (!1186 (merged))
• Added SF_CANBUSTWALLS. Characters require this skin flag in order to break bustable walls like Knuckles. Therefore the bustable behavior is no longer tied to CA_GLIDEANDCLIMB. (!1163 (merged))
• Updated the credits. (!1200 (merged))
• Added a dash state for Tails overlay. (!1210 (merged))
• Let more graphics lumps be replaced clientside. (!1189 (merged))

• Flame Shield and Thunder Shield now put no spin characters into a spin state when using the ability. (!1220 (merged))
• PK3 files with 'holes' may no longer be loaded. The reasoning for this change is that such files can be exploited to show different contents depending on the tool, which could've been used to hide innapropriate or malicious content. (!1275 (merged))
• Updated the credits. (!1308 (merged))
• Added downscaling for APNG. (!1197 (merged))

• SOC now supports caret colors ^A - ^F. (!1295 (merged))
• Ring drain sectors play the ring depletion sound. (!1315 (merged))
• Added a SF_NOSHIELDABILITY skin flag. This flag prevents activating shield abilities for that character. It also disables the attraction shield's targetting arrow. (!1331 (merged))
• Extended font remaps to 16 continuous colors. (!1202 (merged))
• The rejointimeout cvar is now enabled by default, has a visual indicator in the tab HUD, and can be adjusted from Server Options. (!1403 (merged))
