Since protocolbuffers/protobuf#17241 got merged, the following warning is printed when using nanopb:

google/protobuf/runtime_version.py:112: UserWarning: Protobuf gencode version 5.27.2 is older than the runtime version 5.28.1 at nanopb.proto. Please avoid checked-in Protobuf gencode that can be obsolete.

An upstream issue has been created here: protocolbuffers/protobuf#18096

This sounds like mismatched grpcio-tools and python-protobuf versions.

Ah, yeah, no later grpcio-tools available. I hate how bad python-protobuf is at forward/backward compatibility.

@PetteriAimonen Are you aware that this also affects the latest release bin package?

Steps to reproduce:

curl -OL https://jpa.kapsi.fi/nanopb/download/nanopb-0.4.9-linux-x86.tar.gz
tar -xf nanopb-0.4.9-linux-x86.tar.gz
cd nanopb-0.4.9-linux-x86/examples/simple/
 ../../generator-bin/nanopb_generator simple.proto

produces:

google/protobuf/runtime_version.py:112: UserWarning: Protobuf gencode version 5.27.2 is older than the runtime version 5.28.2 at nanopb.proto. Please avoid checked-in Protobuf gencode that can be obsolete.
Writing to simple.pb.h and simple.pb.c

@mrtzcspr I was not, thanks for letting me know. I guess I should lock the versions used for generating binary packages, though then I'd forget to update them..
