Release note

Users can use rw_catalog.actor_id_to_ddl, rw_catalog.fragment_id_to_ddl to query ddl info corresponding to fragments and actors.

LGTM!
Nits: can we rename them to actor_id_to_job and fragment_id_to_job?

Since it's user-facing, I prefer actor_id_to_ddl. job is not really a formalized concept for users. But DDL is.
