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.
Cloud SQL maintains a maintenance changelog for each database engine major version.
