BUG#34231226: Generated classes do not work with the latest Protobuf

nmariz · nmariz · commit 07e3d17dc4dc · 2022-06-07T15:17:11.000+01:00
The latest Python Protobuf package 4.21.0 introduced a breaking change in the compatibility between the resulting generated classes from protoc and the runtime library. To keep backward compatibility, Python Protobuf is now required to be >=3.11.0 and <=3.20.1. The setup.py `install_requires` option and documentation got updated accordingly (added by Git revision 4fb79de). Optional dependencies updated to the approved versions.
