Percona Server for MySQL 8.0.46-40 (2026-11-10)

This release is part of Percona’s MySQL 8.0 End of Life Support – Upgrade to MySQL 8.4 or Stay program. The program provides critical updates and ensures stability for businesses relying on MySQL 8.0 beyond the official EOL.

  • Paying customers can access the full release, including pre-compiled binaries, through the private repository.

  • Community members can build the release from publicly available source code, which is released quarterly.

Upgrading to MySQL 8.4 is recommended, but support for MySQL 8.0 will continue.

Release Information

Percona Server for MySQL 8.0.46-40 builds on MySQL 8.0.46 Community Edition, adding enterprise-grade features and security enhancements from Percona.

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.
