Changelog

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

0.5.2

No schema change. Adds project governance and legal files (NOTICE, AUTHORS, SECURITY, CONTRIBUTING, TRADEMARK). The database objects are byte-for-byte those of 0.5.1; the 0.5.1--0.5.2 upgrade is empty on purpose.

0.5.1 and earlier

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