That is the expected behaviour. Files created using the beta version may end up with metadata that cannot be read. However we will normally fall back to an alternative method of creating the metadata if we get a version mismatch, so the user should not observe an issue other than the exception being logged.
Were you observing some additional ill effect besides the logged exception?

This value is serialized in the meta-data for the RTL type. When deserializing the RTL type meta-data the serialized value is checked against the current constant, and an exception is thrown if they do not match.
