The March 2025 Update is now live.
Update Highlights
This update brings some new content to Sandbox:
There are also further localization improvements to the Sandbox gamemode, more English-only phrases are now translated to player's selected language.
We also have a new mountable game, at the request of its developer:

Players will be able to use maps, models and other assets from this game in Garry's Mod, once mounted through Main Menu's Games section.
This update also adds a large number of new entities to the game, mostly from newer Source Engine games. This should help mappers create even better maps, and potentially improve compatibility with maps from mountable games.
In addition, there were some improvements to the Hammer editor and map compilation tools, further benefitting mappers.
This update also brings partial custom shader support, enabling modders to create fancy effects such as this:
As usual, there is a large number of Lua API additions and fixes, as well as other miscellaneous fixes and improvements for modders as well as players.

This update requires servers to update before you can join them. This means that for a certain period of time after the update releases you may be unable to join servers and get a message saying "The server is running an older version of the game" instead. You will have to wait for servers to update before you can join them again, as well as make sure your game is up to date. You cannot downgrade to a previous version of the game. Please be patient and let server owners update their servers.
