Python patch version compatibility

Hi, I have a question about using cloudpickle to send objects between two different python patch versions (e.g., 3.8.9 vs. 3.8.10). Will the cloudpickle work for different python patch versions? I'm concerned about that because aligning patch version between server and client is too restrictive for our use case, but README says that "Cloudpickle can only be used to send objects between the exact same version of Python". I've tested that serializing objects in 3.6.8 and deserializing them in 3.6.12 works, but I'm not sure it will work for all Python patch versions.

Could anyone answers this question? Thanks!
