Announcements

• Protobuf News may include additional announcements or pre-announcements for upcoming changes.

Bazel

• Bazel 9 tests for csharp, hpb, objc, php, python, rust and upb (#27598) (4469e38)
• Break protobuf dependency on Bazel's proto fragment. Only respect the Starlark versions of --proto_toolchain_for*. This is a breaking change from 35.0, but matches the behavior in 34.x. (1f99c52)

C++

• Add cord setters to repeated string fields. (6efa174)

UPB (Python/PHP/Ruby C-Extension)

• Avoid UB in upb by switching to the XCT section, which will run our constructors before the compiler-generated initializers. (c35b977)
