New
- Enabled Arsenal Mode: Demolition ( Gungame-objective ).
- Set quickmatch to Arsenal Demolition, de_lake.

Graphics
- Replaced Source shadow engine.
- Added support for Intel integrated graphics chipsets.
- Added FXAA.

Sound
- Radically reduced dsp on 3rd person footsteps to address directionality problems.
- Remixed ladder footsteps to prevent players thinking someone was right next to them when they weren't.
- Decreased weapon shot volumes relative to footsteps. This should cause one to increase their volume locally to the level they are used to playing, thereby loudening footsteps in the mix.
- Reduced number of dynamic audio channels, thereby increasing the number of static ones. This is to counter the overrunning of static audio channels and dropping sounds.
- Updated win round music.
- Remixed deathcam music.
- Added round start and team auto select countdown beeps.
- Adjusted soundscapes on most maps.

Game

- Lowered AK47 position to match m4.
- Fixed crouch/jump-crouch seeing through the ceiling.
- Casual mode limit changed from 30 minutes to 10 rounds.
- Fixed exagerated neck hitbox that made headshots much easier.
- Refined most hitboxes to better match player geometry.
- Fixed one-way smoke grenades.

UI
- Implemented achievement medals.
- Dynamically resizing the pause menu panels to match the number of options present. Fixing the back button on the subpanel to swap to a button hint string for console/controller.
- Fixed renaming of files when pressing F5 for death cam.
- Fixed overlap between Health/Armor panel and spectator panel.
- Adding playing joing messages and playing as bot message to mini scoreboard
- Adding hud alerts panel for telling you match state
- Changed art and animation for alert, achievement, info and defuse panels.
- Added icon for defusing without a defuse kit to defuse panel.
- Updated some weapon images.
- Added element to the team miniscoreboard that displays when you're currently controlling a bot as well as what team you are playing on every time you spawn.

- Added CT defusing state to player ID.

General
- Fixed bug where spectating player's view would pop back up when observed player was in full duck.
- Fixed miscellaneous map bugs.
- Remove capping mouse accel values (caused negative in-game effects)
- Reducing the latency between bomb defuse thinks, which causes the defuse HUD to feel laggy and allows a non-fixed duration of time where you can let go of the defuse button and still be counted as defusing as long as you press defuse again before the next c4 think.
