Via CS:GO Blog:
- Made bomb plant and bomb defuse sounds more audible with sound occlusion on.
- Fixed an exploit that allowed ambient sounds to be completely disabled.
- Re-enabled SSE4 optimizations for string tables and added -nosse4 command line option to disable SSE4.
- “find” console command now allows specifying multiple search strings. For example, “find decal r” will find commands and variables that contain both “r” and “decal”.
