Maintenance changelog
This page explains maintenance changelogs and provides links to changelogs for
each database version.
Cloud SQL regularly updates the software on Cloud SQL instances
through new maintenance versions. With new maintenance versions, Cloud SQL
releases new features, security patches, bug fixes, performance improvements,
and more. Your Cloud SQL instances are kept up-to-date with the
latest maintenance version through self-service maintenance or through scheduled
maintenance, which Cloud SQL performs once every few months.
