Security

• breaking: Added default limit to how much data Bytes::from_request will consume. Previously it would attempt to consume the entire request body without checking its length. This meant if a malicious peer sent an large (or infinite) request body your server might run out of memory and crash.

  The default limit is at 2 MB and can be disabled by adding the new DefaultBodyLimit::disable() middleware. See its documentation for more details.

  This also applies to String which used Bytes::from_request internally.
