CS:GO 01.05.2018 Update
Introducing animation and sound changes
A new update hit Counter-Strike: Global Offensive, replacing animations of some of the T-side weapons (MAC10, MP7 и MP9) with a two-handed version for improved weapon recognition. Also, Valve modified ShortNuke (the 2x2 version of de_nuke) and fixed some of the game's sound issues.
You may find the full list of changes below.
Gameplay changes
Replaced custom Terrorist one-handed walking animations for the MAC10, MP7, and MP9 with an alternative two-handed version to improve weapon recognition at a glance.
Sound changes
Enabled streaming audio by default, making use of the ‘sound cache’ unnecessary. The sound cache can be forced back on by setting snd_disable_legacy_audio_cache 0 if any issues are found.
Weapon reload sounds now follow the reloading players as they move around.
Fixed sound device override exploit to cancel sound.
Map changes
ShortNuke:
Added more spawn points per side.
Fixed model occlusion bug inside vent.
Added solid background to top of yellow crane inside site.
