An update for Counter-Strike: Source, Day of Defeat: Source, Half-Life Deathmatch: Source, Half-Life 2: Deathmatch, and the Source SDK 2013 Base has been made available.

Important note for SDK mod authors: This update replaces the current main branch of the SDK 2013 Base with what was previously the "beta_test" branch. The previous SDK 2013 release branch as well as the outdated "upcoming" branch are now available for a short time as "previous" and "previous_upcoming" respectively.

The major changes include:

• Fixed potential security issues (thanks to Justin G. (aka sigsegv), Nathaniel Theis, Simon Pinfold for these reports)
  
• Fixed a case where changelevel2 would print a map not found error and fail to function in SDK2013 mods
  
• Fixed an exploit that could be used to crash dedicated servers
