We have updated the public release of Team Fortress Classic. This update contains all the changes from the recent beta, thanks to the whole community for their help with testing and suggesting new features.
Changes in this update are:
Converted Team Fortress Classic to the new SteamPipe content system, for optimized delivery of the game
Added support for Mac OS X and Linux operating systems
Improved OpenGL rendering pipeline and output to leverage the capabilities in todays GPU
Linux and OS X users can simply install the Team Fortress Classic application to access the beta. For Windows users right click the game in your Library, choose properties and then go to the Beta tab. Select the SteamPipe beta to start testing. Under windows to opt out of testing simply deselect the beta option on this same page. If you opt into the Beta under Windows please use the Local Files tab in Steam to validate your install once you have opted into the beta.
