Source Engine Changes (CS:S, DoD:S, TF2)

* The mat_hdr_level, r_rootlod, and r_waterforceexpensive settings are now saved in the user’s config file.
* Fixed clients being able to connect to servers with spoofed SteamIDs.
* Fixed a bug where some video configurations could get reset by restarting the engine.
* Fixed materials compiled into a map not being loaded correctly if they’re in the root materials folder.
* Fixed a case of uneven performance on multicore machines.
* Fixed point contents not respecting detail brushes. This fixes a bullet penetration bug in some community maps.
* Fixed clients being able to spam servers using the ai_set_move_height_epsilon, mission_show, and sv_querycache_stats commands.
* Audio fixes:
o Reduced overlap in the sound timing code.
o Fixed a case where audio could skip.
o Fixed voice communication getting corrupted while playing on a Mac.
* sv_pure 2 now protects the game_sounds files in the scripts directory.

Counter-Strike Source

* Fixed prediction errors that were causing greater weapon inaccuracy (bullet spread) on client than server.
* Made the bomb the primary target of a +USE command. This fixes a problem with objects placed around the bombsite interrupting defuse attempts.
* Fixed the ‘skating’ behavior that could occur when a bomb planting attempt was aborted. Also fixes the resulting out of sync hit boxes.
* Fixed bug in which a player who crouched rapidly and repeatedly was seen as stationery by other players.
* Fixed problem in which the sound of a reload that was occurring when a player was killed persisted into spectator mode, making it sound like a reload was taking place near the spectated player.
* Gave chat interface priority over scoreboard to reduce conflict between the two.
* Increased size of HUD icons.
* Fixed bug with env_hudhint that caused problems when its value was greater than 255 characters.
* Made the message of the day screen dismissible by hitting ENTER.
* Fixed servers not being able to set sv_hudhint_sound.
* Gun sounds now match up with the framerate dependent sound timing, and fixed the framerate dependent jittering bugs.

* Stats:
o Fixed an issue that could cause loss of player stats if network connectivity was lost briefly, just after launching the game.
o Fixed an issue that caused the favorite weapon to display incorrectly on the stats summary page when a player achieves the most kills with a knife or grenade.
o Made newly-earned achievements and stats immediately update in the achievements and stats panels instead of showing stale data.
o Improved the font on the achievement toast.

* Community Requests:
o Added cvar sv_enablebunnyhopping, defaulted to 0. ( A value of 1 autotags the server with “bunnyhop” )
o De_dust and De_dust2 updated.
+ Fixed several exploits.
+ Fixed collisions on crenellation and domes.
+ Fixed minor visual glitches.
+ Adjusted HDR settings.
+ Removed dust clouds.
* Added console variable cl_hudhint_sound.
