A small-but-important release to fix many of the hotkeys issues found in the 11.0 release, plus an issue with in-game where you could not hold down both the left and right mouse buttons without "one resetting the other" in some circumstances.
For the full list of the fixes in this release (there are no new features), please see the 2023.11.1 milestone page.
As already mentioned in the original November release notes, please be aware that following the recent licensing changes, where now everyone can get all modules free for non-commercial usage (apart from the consoles), 2023.11 is the last version we are going to release on our separate "GameMaker Desktop"/"GameMaker Mobile"/"GameMaker Web" products here on Steam.
Please install "GameMaker" in your Steam library now and use it instead of this one (if you are not already doing so), as that's the only Steam product which will receive future version updates!
