CHANGELOG

@@ -5,6 +5,43 @@ Quake 2 8.41RR8:
 - Full support pcx version 5 format,
 - Rework image load code.
 
+Quake II 8.40 to 8.41:
+- Fix an endless loop in the OpenGL 1.4 renderer crashing the game and
+  blocking further progress under some circumstances. (by protocultor)
+- Don't force a platform dependend, hard coded SDL audio driver, let SDL
+  choose the driver instead. This may fix the SDL audio backend on some
+  platforms. The driver can still be overridden by setting `s_sdldriver`
+  to something else than `auto`. Under Windows `s_sdldriver` defaults
+  `directsound` because `auto` may choose an incompatible driver.
+
+Quake II 8.30 to 8.40:
+- Implement `g_quick_weap`. If set to 1, both weapprev and weapnext
+  commands will count how many times they have been called, making
+  possible to skip weapons by quickly tapping one of these keys. (by
+  protocultor)
+- Fix `gl1_overbrightbits`, allowed values are now 0, 1, 2 and 4. (by
+  protocultor)
+- Sort player skins case insensitive. (by apartfromtime)
+- Implement `cl_showspeed` to show the current player speed (by Feels
+  Duck Man)
+- Add texture filtering options to the video menu (by apartfromtime)
+- Implement `cl_laseralpha` to control how transparent laser beams are.
+  (by BjossiAlfreds)
+- Experimental support for SDL 3. Requires SDL 3.1.2.
+- Reimplement multitexturing for the OpenGL 1.4 renderer. Controlled by
+  `gl1_multitexture`, enabled by default. (by protocultor)
+- Optimize dynamic lights and texture allocation in the OpenGL 1.4
+  renderer. (by protocultor)
+- Implement gyro tightening for gamepads and joysticks. (by protocultor)
+- Support long player skin names. (by 0lvin)
+- Add a very simple download filter. Files ending in .dll, .dylib and
+  .so are always filtered to prevent code injection.
+- Don't load OpenAL and cURL libraries if thy are configured with a full
+  or relative path.
+- Work around naggy help icons. (by BjossiAlfreds)
+- Group draw call in GL1. This yields huge performance gains on slow
+  GPUs. (by protocultor)
