Today's update brings a small amount of vital improvements to the stability and security of the game. This update is mandatory meaning servers will have to be updated before players can join them.
The update fixes some Team Fortress 2 maps crashing when looking at certain spots, and those maps now also properly load detail props. A long standing crash with decals on very high quality models was fixed as well.
This update also brings a new hashing algorithm for Lua files which will prevent people from running custom clientside code on servers when they are not supposed to be able to.
