A new update for Team Fortress 2 has been released via Steam (as per usual), this time around improving Linux connection servers, and rectifying an error dialogue among these main updates:

• Added an optional per-map particle manifest called _particles.txt, which should be located in the maps directory, so map authors can load custom particle files
• Fixed minicrits resulting in reduced damage for weapons at close ranges
• Fixed the Cloak and Dagger not regenerating at the correct rate
• Fixed setinfo exploit that allowed restricted convars to be set while connected to a server
• Fixed tournament mode being interrupted if mp_timelimit hits before both stopwatch rounds have been played
• Fixed "jointeam unassigned" exploit
• Fixed being able to respawn during the chat time before a level change
• Fixed "sensitivity" ConVar not capping the upper value which sometimes caused a server crash
• Prevented some exploits based on mat_dxlevel being changed in-game
• Updated ripple effects for water drips to improve performance

As per usual, the update will automatically apply the next time you restart your Steam client.
