3rd UPDATE: Nevermind, there's a rollback.

2nd UPDATE: Command has now been removed, but it doesn't look like anyone that used it suffers a rollback. GG Valve..

April 30, 2008 - Team Fortress 2 Update Released

Updates to Team Fortress 2 have been released. The updates will be applied automatically when your Steam client is restarted. The specific changes include:

Team Fortress 2 Client

* Removed TF2 achievement console commands

Team Fortress 2 Server

* Fixed clients being able to trigger sv_soundscape_printdebuginfo on the server
* Fixed potential "nuke" exploit in rcon subsystem



UPDATE: Valve has made a major gaff with the release of the new medic unlockable weapons - rather then grind through every achievement, Valve has left open a client command "achievement_unlock_all" that completes all achievements and thereby unlocks the 3 new weapons. The only questions remaining is.. who screwed that up?
