In the version-pinned C2PA pages, 1.0 and 1.2 mention c2pa.actions.v2 only as an example of label versioning; 1.3 (its own history dates it April 2023) is the first to define the v2 actions assertion, with a separate actions-map-v2 CDDL rule. Dates come from the specification's own history, not independent release records.
