  "message": "Breaking change: Raise IndexError for out-of-range indices in RepeatedContainer.pop() in Python upb implementation.\n\nPreviously, calling pop(index) on a repeated field with an index greater than\nor equal to the container\u0027s length emitted a FutureWarning and clamped the\nindex to the last element, removing and returning the last element instead. It\nnow raises IndexError, consistent with Python\u0027s native list.pop() behaviour and the\nPython protobuf pure-Python and C++ implementations.\n\nhttps://protobuf.dev/news/2026-09-22/#repeatedcontainerpop\n\nPiperOrigin-RevId: 1002527165\n",
