  "message": "upb: identify extension fields by their offset instead of a mode flag.\n\nEvery extension field already has offset 0, which no regular field can have,\nsince every message starts with its upb_Message header. Reserve that offset as\nkUpb_MiniTableField_ExtensionOffset, and make upb_MiniTableField_IsExtension()\ncheck it instead of the kUpb_LabelFlags_IsExtension mode flag, which is\nremoved. This frees a bit of upb_MiniTableField\u0027s mode.\n\nSince extension fields keep offset 0, minitables generated before this change\nare still interpreted correctly.\n\nPiperOrigin-RevId: 1007700495\n",
