Breaking Changes

• 🔒️ Add strict_content_type checking for JSON requests. PR #14978 by @tiangolo.
  • Now FastAPI checks, by default, that JSON requests have a Content-Type header with a valid JSON value, like application/json, and rejects requests that don't.
  • If the clients for your app don't send a valid Content-Type header you can disable this with strict_content_type=False.
  • Check the new docs: Strict Content-Type Checking.
