About this File:

Minor optimizations in server and client engine for lower cpu usage. Client can record game audio to a wav file. wav_record starts recording wav_stoprecord stops recording cl_wavefilerecord 1 will start recording from the moment a demo is loaded. "Unable to load an official pak file" now reports the pak filenames in the console. Win32 and Linux sound cvars are now unified: s_khz, s_bits, s_numchannels s_khz is now a CVAR_LATCH. Players can override unsafe cvars (e.g., from a crash) with com_ignorecrash 1 Server can give alternate messages to "server is full" by changing the cvar sv_fullmsg Server can redirect clients to other servers when full (e.g. sv_fullmsg "ET://host.to.redirect.to:port") Server will switch to GT_WOLF if "map" can't start a campaign. /demo can now specify .dm_83 extension explicitly, and will try dm_83 and dm_84 if extension isn’t specified. Abbreviated snapshots are now sent when clients aren't fully connected. Saves bandwidth on map rotations. Client may move the demo recording statusline with cg_recording_statusline. 0 hides it completely. /buyNow, /singlePlayLink commands removed. 'MODS' menu added. Anisotropic texture filtering is now supported in renderer. Enable with r_ext_texture_filter_anisotropic 1 and use r_textureAnisotropy to set the filtering level. cg_draw2D is no longer cheat protected. Wounded freelook is now enabled (a la RTCW). It is also completely moved clientside so there is no lag.
