  "message": "Breaking change: Return NotImplemented when comparing descriptor containers with unrecognized types in the C++ and upb Python implementations.\n\nEquality comparisons (\u003d\u003d and !\u003d) between descriptor containers and objects of unrecognized types previously emitted a FutureWarning and treated the objects as unequal.\n\nThey now return NotImplemented, following standard Python comparison behaviour\nso that the reflected comparison on the other operand is attempted.\n\nhttps://protobuf.dev/news/2026-09-22/#return-notimplemented-for-unrecognized-types\n\nPiperOrigin-RevId: 1002560722\n",
