The base serialization is stable and compatible across Python versions. However pickle files can serialize entire Python objects, including from custom and third party code. Compatibility of serialization then depends on the versions of the code that implements those objects, which is often not well managed.
Could be wrong, but I do not believe this is true anymore. There are pickle versions, but I believe the format has been standardized such that you should be able to freely move between Python releases.
