Remaining `pydantic.v1` imports are wrapped with warning suppression to avoid the "Core Pydantic V1 functionality isn't compatible with Python 3.14" warning. ## 4.55.3 **`(fix):`** Fix body property named `json` clashing with the `json` module import when generating `json.dumps(jsonable_encoder(...))` for multipart file upload requests. The `json` module is now aliased as `_json` when a body property named `json` is detected. ## 4.55.2 **`(fix):`** Add websocket compatibility shim for websockets library v14. The generated SDK now uses a `core/websocket_compat.py` module that abstracts the `InvalidStatusCode` vs `InvalidStatus` exception difference, ensuring compatibility with both websockets v12-13 and v14+.
