I was confused by sentence at https://developers.google.com/protocol-buffers/docs/reference/python-generated#sharing-messages: "Prior to Python 4.21.0, Python apps could share messages with C++ using a native extension." Latest python version is 3.11 at the moment. Now I know that 4.21 is about protobuf Python API. I propose to update above sentence to (there is one more place to fix on same page) "Prior to Python API 4.21.0, Python apps could share messages with C++ using a native extension." I don't know where is the documentation repo to make PR.
