## Changed
- **Breaking: Message Limit Error Status Code Change** — The API now returns `429 Too Many Requests` when a chatroom's message limit is reached. Previously, this returned `422 Unprocessable Entity`.

### Action Required

If your integration handles `422` responses for message limit errors, update your error handling to check for `429 Too Many Requests` instead.
