2023.11 brings lots of behind-the-scenes performance improvements to both the IDE and Runtime; various new functions have been added to expand what you can do with buffers and rooms; following on from the SDF Effects added last release, you can now apply these effects to text tracks within your Sequences; you can now create your own Game Strip projects (and there is a new template you can use to learn about Game Strips); and there is a very large number of bug fixes and also some of the popular community requests since our public request system was revealed a few months ago.
Always ensure your SDKs and other external tools are the correct versions for this release before doing any builds - Required SDKs FAQ
Also, if you use antivirus/antimalware or any restricted user permissions on your machine, always check your external settings allow for this new release to work properly - User Permissions and Internet Access Required by GameMaker
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!
