duan-n2d opened a new pull request, #77012:
URL: https://github.com/apache/airflow/pull/77012
Registered serde deserializers are expected to refuse a payload stamped with
a version newer than the class doing the deserializing, so an older Airflow
fails loudly on data written by a newer one instead of misreading it. The other
registered serializers already do this; uuid and datetime did not, and the
serde framework does not cover for them because its own version check only
applies to the attr/dataclass fallback.
Nothing is affected today since both serializers are still at the version
they ship with. The guard is needed so that the next bump of either __version__
is enforced from the start.
