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.

0.5.3

Completes the copyright and licensing files: the copyright holder’s full legal name in LICENSE and README, and a per-file SPDX header on every SQL source file. No schema change.

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.
