Percona Server for MySQL 9.7.3-3 (2026-11-10)

Get started with Quickstart Guide for Percona Server for MySQL.

Percona Server for MySQL 9.7.3-3 includes all the features and bug fixes available in the MySQL 9.7.2 Community Edition and enterprise-grade features developed by Percona.

A note on MySQL 9.7.3

Percona Server for MySQL 9.7.3-3 is not based on the MySQL 9.7.3 release. MySQL 9.7.3 is a Critical Security Patch Update (CSPU) — a targeted security release that Oracle can issue between quarterly Critical Patch Updates (CPUs) when needed. The MySQL 9.7.3 CSPU applies to the MySQL Server Docker image only, and its fixes do not affect Percona Server for MySQL.

Bug Fixes

  • PS-11950: mysqldump did not always dump tables with compressed columns correctly. If a column comment or another quoted string in the table definition contained text that looked like a compressed column attribute, mysqldump changed the table definition in the dump, so it was different from the original table. mysqldump also did not correctly dump or restore some compression dictionaries, such as dictionaries with names containing quotes, spaces, reserved words or non-ASCII characters, or with non-ASCII data.
