The biggest changes this update brings are to our Steam Workshop support.

Here are the benefits of the new system:

• Addons will have a much higher size limit, up to 2GB
• New or updated addons on Steam Workshop will display their real, uncompressed size
• New or updated addons will take less space on your HDD/SSD
• There will be no negative impact on download/upload sizes
• Players will be able to update their uploaded Dupes, Saves and Demos from in-game

Please note that new or updated addon files will no longer be stored in your addons/ folder, instead they will be stored by Steam in steamapps/workshop/ folder of your Steam game library.

We have also added the ability for players to update their existing Dupes, Saves and Demos uploaded to Steam Workshop. The process for this is very simple - simply press "publish" on the new version of your local content, such as a Dupe you created, and select one of your existing items on the right in the reworked UI for publishing the content:


We have also added "Dupes" section to the main menu, allowing you to delete your local Dupes from in-game, without a need to open game's install folder.

If you are using 3rd party tools that do not use gmpublish.exe to upload content to Steam Workshop then addons published with those tools after the update may cease to work.
This does not apply to already existing addons, however the benefits above only apply if you are using the new version of gmpublish.exe (v1.2)

Existing addons can take advantage of the new system and its benefits by simply updating using the new gmpublish.exe (v1.2). Please note that this is a one way process and there's no going back to the old system once you convert your addon, meaning you won't be able to update it again with old versions of gmpublish.exe or 3rd party tools that do not use gmpublish.exe (which realistically shouldn't matter).

If you are currently using steamworks.Download in conjunction with game.MountGMA, that will also cease to work for new Steam Workshop content. You will need to switch your code to use steamworks.DownloadUGC instead. Please note that it takes a WorkshopID directly, not a file ID like its predecessor. All of this is documented on the Official Wiki.

In addition to the Steam Workshop support changes, this update includes the usual fixes and improvements across the game. We have updated the Player Model selector in Sandbox to include a search bar so it is easier to find specific models.

We have also translated certain previously untranslated parts of the game, such as the Publish creation and the Player model selector menus, among other smaller changes.
Source Engine menus and UI language is now tied to your language selected in Steam. This behavior can be overwritten with the -language launch parameter.

The 64bit update is still scheduled to be released on 24th of January, this friday.
The 64bit update has been delayed.

Hello everyone.

The next Garry's Mod update is coming soon. Actually 2 of them.

The first update is scheduled to release on 21st of January (around the usual 4PM GMT) and will bring changes to Steam Workshop support in Garry's Mod. More details are below. This update is recommended to be installed on all servers, but will not be enforced.

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

The second update is scheduled to release on 24th of January and will bring the long awaited 64bit builds and a new built-in browser engine - Chromium. This second update will not affect servers in any way, so it won't be necessary for server owners to perform any updates.

We are moving Garry's Mod to a new Steam API called ISteamUGC, which will bring a bunch of nice features for everyone.

Here's what's changing:

• Addons will no longer have a size limit, meaning no more separate downloads for map content, etc
  
• New or updated addons on Steam Workshop will display their real, uncompressed size
  
• New or updated addons will take less space on your HDD/SSD
  
• There will be no negative impact on download sizes
• Players will be able to update their uploaded Dupes, Saves and Demos from in-game

If you are using 3rd party tools that do not use gmpublish.exe to upload content to Steam Workshop then addons published with those tools after the update may cease to work.
This does not apply to already existing addons, however the benefits above only apply if you are using the new version of gmpublish.exe (v1.2)

Existing addons can take advantage of the new system and its benefits by simply updating using the new gmpublish.exe (v1.2). Please note that this is a one way process and there's no going back to the old system once you convert your addon, meaning you won't be able to update it again with old versions of gmpublish.exe or 3rd party tools that do not use gmpublish.exe (which realistically shouldn't matter).

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.

Hey everyone!

We have released an small patch that addresses a few small issues while we work on a bigger update that will bring many improvements to Workshop support all around the game.

The entire change log for this patch is as follows:
* Improved handling of Steam Workshop downloads when joining servers, fixing addons not updating properly among other improvements
* Fixed recording Demos creating a black icon

This update is for the game client only, servers do not need to be updated.

We have released an small hotfix update that addresses a few issues from previous update.

The entire change log is as follows:
* Fixed a crash issue in VertexLitGeneric shader with missing base texture
* Performance improvements to clientside DTVar callbacks
* Updated language files

This update is for the game client only, servers do not need to be updated.

Among many smaller changes and improvements, this update brings back the HEV suit functionality from Half-Life 2, including limited flashlight, oxygen and sprint energy. By default the suit systems are disabled, and you can enable this when starting a new game on the panel above "Start Game" button, or while in-game in the Utilities tab in Sandbox's Spawnmenu.

We have also added a feature called Dynamic Render To Texture shadow angles:

While this feature is primarily aimed at map makers, we have added a bunch of console variables for everyone to mess around with:

• r_shadow_allowdynamic 1 - Allows dynamic lights, such as the Light tool, to make use of this feature
  
• r_shadow_allowbelow 1 - Allows lights below an entity to also affect shadow angles
  
• r_shadowfromanyworldlight 1 - Makes ALL light sources affect shadow angles, as opposed to only map curated ones
  
• r_shadow_lightpos_lerptime 0.5 - How long it takes for the angles to change from one light source to another
  
• r_shadow_shortenfactor 2 - The higher the number, the more towards the ground the shadow will point

If you wish to disable this feature altogether for whatever reason, you can use the following command:

• r_shadowfromworldlights 0

Along with these 2 features, there are a whole slew of smaller changes and fixes, such as more improvements to map loading from other games like Counter-Strike: Global Offensive, whose maps should look less broken with this update, as well as being able to load its de_dust2 version and the dz_sirocco Danger Zone map thanks to the increased map displacement limit.

We are also introducing a number of visual fixes, such as Lamp tool glows now working properly in mirrors, a fix for the long standing issue of sun disappearing randomly when looking at it and some decals not receiving shadows from projected textures (Lamp Tool) on gm_construct and many other maps.

The Hammer Editor also saw some improvements, fixing checkerboard reflections and a new ability to simply drag'n'drop .vmf files onto Hammer to open them, so you no longer have to manually navigate to your files using the Open File dialog.

Special thanks to Badger for reporting and suggesting a fix for a security issue.

Hey everyone, we have just dropped another small hotfix update that addresses a few more issues that came up after release of the September 2019 update.

Complete list of changes is as follows:

• Fixed a memory leak with engine traces
  
• Hopefully fixed NW2vars being wonky on players after the September 2019 update
  
• Fixed a small exploit

It is highly recommended that server owners update their servers to receive the memory leak fix.

Hey everyone, dropping this small hotfix update that addresses a few issues that came up after release of the September 2019 update.

Complete list of changes is as follows:

• Fixed FPS issues after the update
  
• Fixed an issue with Global NWVars not syncing to client when set during server start up
  
• A few improvements and fixes to addon menu and custom .gma files
  
• Fixed host_timescale not resetting with sv_cheats 0 and causing all entities to appear laggy/stuttery
  
• Fixed NPC driven vehicles not driving at all, such as the Combine APCs on Half-Life 2 maps
  
• We have disabled spawnlist saving to Steam Cloud for the time being as it caused problems for people playing Garry's Mod on multiple computers with the same Steam account

Server owners only need this hotfix if they use the SetGlobalX functions in Lua.

If you are still wondering about the Half-Life 2 style crosshair after the update, simply restarting your game should fix it for you.

This update brings a bunch of improvements to the built-in weapons as well as better support for NPCs being able to use modded weapons.

This update is optional for server owners, but it is highly recommended to update to get all the new fixes and features.

Since Half-Life 1 weapons got a lot of love in previous updates, it is only fair that Half-Life 2 weapons get the same treatment, and with this update we've resolved most if not all visual and audio problems with the built-in Half-Life 2 weapons. No more broken sounds and effects.

We have also added better NPC support to scripted weapons, so addon makers can now control exactly how the NPCs can use their weapons. As an example, the built-in Flechette Gun now has full NPC support, meaning it can be picked up by Citizens/Rebels from the ground and used properly against their enemies.

Your in-game content such as Dupes (built-in, not modded), Saves, Spawnlists, etc now also saves on the Steam Cloud automatically. This feature was enabled a few weeks ago, but we are mentioning it here so you are aware. There is a hard limit of 10000 files per account for this, so be careful if you have excessive amounts of saves and whatnot, if you reach the limit, your new content will not be saved on the Steam Cloud until you delete some old stuff first.

There has also been some improvements to CS:GO/Left 4 Dead map support, fixing some flickering models around those maps and fixing unexpected water effects in certain places on some CS:GO maps.

The Half-Life campaign support continues to improve, as level transitions now work properly in singleplayer, Jeeps get their Gauss Guns back in Half-Life 2 maps, the Half-Life 2 teleporter sequence now slows down the player properly, added a new feature to limit player's ammo (with the ability to match Half-Life defaults) and the suit chargers were changed back to restore 75 armor by default just like in Half-Life 2.

You will find the complete list of changes for this update at the link below.
