Dear László, Please considering update protobuf to 3.34.1 in experimental. I've been working on packaging the latest bazel in Debian. And I met a compiler error. I think it is related to the protobuf version that needs to be updated. Here are the error: src/main/protobuf/file_invalidation_data.proto: is an editions file, but code generator --java_out hasn't been updated to support editions yet. Please ask the owner of this code generator to add support or switch back to proto2/proto3. I've added "-experimental_editions" when running protoc, but this doesn't fix the issue. I can help with the updates too if you allows me to work on it. I've also checked bug #1034668 and #1089622. And #1034668 I think it is already fixed. Yours Sincerely, Paul
