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.

• Fixed a crash with decals on high poly models
  
• Fixed a crash with Projected Textures
  
• Fixed crash issues on some TF2 maps
  
• Fixed crash issue with physenv.AddSufraceData()
  
• Fixed not being able to start a new game with too many game.AddDecal() calls
  
• Fixed a crash issue with env_fog_controller
  
• Fixed crash exploits with parenting of unremovable entities to removable ones and deleting them this way
  
• Fixed certain players not being able to be muted on servers with large populations
  
• Changed Lua file hashing algorithm to improve security

Unlike many previous updates, this one will require servers to update before you can join them. We try to keep such updates to a minimum, but it was necessary for this update.

This means that for a certain time after the update you may get a message such as "The server is running an older version of the game" when connecting to your favourite servers. You will have to wait for servers to update before you can join them again.

You CANNOT downgrade to a previous version of the game.

Hi everyone,

We are planning to release the next Garry's Mod update next week, on October 17th around 3PM GMT.

You can find the list of changes that will be coming here:
http://wiki.garrysmod.com/changelist/prerelease/


We kindly ask anyone willing to help us test this update before it releases (especially modders and server owners), to minimize any potential problems with the update.

You will find instructions on how to use the upcoming update below.

Please note that this update NOT backwards compatible with the current version of the game, so you won't be able to play on normal servers while on the "prerelease" branch.
After the update releases you will have to wait for server owners to update their servers before you can play on them.

You can report any found issues in the comments below, or on our official bug tracking repository on GitHub: ( be sure to search before posting )
https://github.com/Facepunch/garrysmod-issues

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

If you want to set up an SRCDS instance using the Pre-Release branch, see this article: https://wiki.garrysmod.com/page/Hosting_A_Dedicated_Server.

How to switch game branches:

1. Exit the game
   
2. Right click on Garry's Mod in Steam and select Properties
   
3. Go to the Betas tab and select your desired branch

None - This is the normal version of the game
Pre-Release - This is the next update
Dev - This is a bleeding edge version of the game, expect it to contain more bugs than usual

We're releasing a small hotfix to address a recently found exploit that allowed users to execute arbitrary Lua scripts on servers. If you run a server, you should update it.

It's a very non-intrusive update, so there should be no risk of anything breaking, except - potentially - third-party binary modules.
