# 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.

## 0.5.2

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.
