Changelog

Versions are released on PGXN. Each upgrade script (pg_recall_guard--OLD--NEW.sql) documents, in its own header, exactly what changed and why; that is the authoritative per-version record.

0.2.1

No schema change. Adds project governance and legal files (NOTICE, AUTHORS, SECURITY, CONTRIBUTING, TRADEMARK). The database objects are byte-for-byte those of 0.2.0; the 0.2.0--0.2.1 upgrade is empty on purpose.

0.2.0 and earlier

See the header of each pg_recall_guard--*--*.sql upgrade script and the release notes on PGXN.
