An update on the Update
The reason for the recent update was to move Counter-Strike Source (CSS) from the older HL2 version of the Source engine to the most recent version. This brings the CSS codebase in-line with our other games. This resolves long standing issues associated with the older engine and allows us to benefit from features and bug fixes in other source games as they come online, such as improved graphic effects and more accurate hit registration.

During this process we created some unintended side effects, these are bugs. We are actively investigating all reports.

A good example of this is bullet penetration changing on Linux Servers only; not Windows Servers. This was a subtle bug to track down and understand. It has been fixed.

Rest assured we will continue to fix old and new CSS bugs. We want to retain the CSS gameplay experience that you know and love. We would also like to thank everyone reporting bugs and posting constructive feedback. This is an invaluable part of the process.
