Opik 2.0.45 ships automatic V1→V2 dataset migration and version filtering for prompt management. Backend metadata parity testing ensures reliability.

Why it matters: Version filtering API enables fine-grained prompt management. Auto-inference migration simplifies dataset upgrades. Deploy as routine update; test migration in staging before production rollout.
