Yep. They’ve primarily (entirely?) involved removing ancient libraries from stdlib, usually with links to maintained 3rd party libraries. People who can’t/won’t upgrade to newer Pythons, perhaps because their old system that uses those old modules can’t run a newer one, aren’t affected. People using newer Pythons can replace those modules.

There may be a person in the world panicking that they need to be on Python 3.13 and also need to parse Amiga IFF files, but it seems unlikely.
