There were some breaking changes within Python 3.10, mostly esoteric features that didn't seem to be used that much. Lots of deprecation warnings though and some C API changes that did break at least one package I used. When I worked on patching/rebuilding all the Python packages for Alpine's upgrade to Python 3.10 I remember quite a few things being broken and needing patches (maybe about 5% of the overall packages), but a lot of those were also test failures due to the new deprecations, so while some stuff did truly break, it was pretty rare.
