An update has been released which fixes an issue that allows malicious clients to cause game-servers to crash. If you don't want this to happen to your server, you should update it.

All dedicated servers should be updated through either your Game Server Provider's control panel or SteamCMD.

Edit:
If it says 'content file is locked', contact Steam Support for help.

Your free antivirus is most likely deleting the game or update files causing it all to die. Add Steam to your AV exclusions, restart Steam, and try updating again.

A new client update has been released!

The entire change log is as follows:

• Fixed a crash related to certain models and model detail setting
  
• Fixed another crash related to decals
  
• Fixed a very common crash to do with .png material unloading
  
• Fixed a very old and common crash during loading screen when loading a map from an addon
  
• Set r_radiosity back to 3 by default because 4 breaks community maps too much
  
• Stopped reserved_spot from ever being created as it breaks ladders

This should improve client stability after previous update.

The update will be automatically downloaded when you restart your game.
Servers only need an update if they want the ladder fix.

A new update has been released!

The most notable changes here are bug fixes and performance improvements related to shadows.

Third-Party binary modules (or cheats) that use the internal ILuaInterface interface may no longer function after this update. Any binary modules using the official ILuaBase interface should not be affected.

The update will be automatically downloaded when you restart your game.

Servers do not need to be updated before you can play on them, but it is highly recommended to update your servers to receive the latest features and bug fixes.

Thanks to everybody who helped with testing the update and reported bugs/problems.

You can find full changelist here.

Hello everyone!

The next update for Garry's Mod is coming soon.

Currently, the update is planned for the 17th of April.

The Pre-release Steam Beta branch for Garry's Mod has been updated and contains all the changes that will be included into the next update.

You can see the full change list for the next update as well as how to join or leave the Pre-release branch here:
http://wiki.garrysmod.com/changelist/prerelease/

The update is currently compatible with all servers, so you can help us test it, enjoy its many benefits like crash fixes and performance improvements at the same time!

We ask you, players and modders alike, to help us test this update so that there will be as few problems as possible on release.

We urge you to spend as much time as convenient for you in single player, testing your addons and whatnot or playing on multiplayers servers, and report any issues you find that did not happen before here:
https://github.com/Facepunch/garrysmod-issues/
Or at least in the comments of this announcement.

If you own a Garry's Mod server, we highly recommend you test your server on the Pre-release branch. Information about using experimental branches on dedicated servers can be found here:
