# Changelog Versions are released on [PGXN](https://pgxn.org/dist/pg_living_assertions/). 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.
