A note on MySQL 8.4.12
Percona Distribution for MySQL 8.4.12 is not based on the MySQL 8.4.12 release. MySQL 8.4.12 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 8.4.12 CSPU applies to the MySQL Server Docker image only, and its fixes do not affect Percona Server for MySQL.
