Thanks much for the info. In addition to grpc-java, I'm also using grpc-python but don't see any protobuf 4 upgrade issues here:
https://github.com/grpc/grpc/issues?q=is%3Aissue+is%3Aopen+protobuf+4 Do you have any insight about protobuf 4 support for python grpc specifically (or other languages more generally)? It looks like the languages try to stay in sync wrt major and minor segments, but I imagine the teams have different priorities. Or should I open an issue for python grpc wrt protobuf 4 support? Thanksinadvance.
