Percona Distribution for MySQL 9.7.1 using Percona Server for MySQL has been released

Percona Distribution for MySQL 9.7.1 using Percona Server for MySQL has been released on Wednesday, August 05, 2026.

Try it out using the Installation guide.

Builds and packaging

  • Percona Server for MySQL releases include a mixture of Profile-Guided Optimization (PGO) and non-PGO builds. Where PGO is enabled, the compiler uses runtime profiling data from representative workloads to guide optimization, which can improve throughput and reduce latency compared with non-PGO builds.

  • See Profile-Guided Optimization (PGO) and non-PGO builds for benefits, considerations, and which build is published for each platform.

  • In Percona Server for MySQL 9.7.1-1 only, Debian and Ubuntu (APT) packaging was reorganized to align more closely with upstream MySQL. Several packages were split into separate components, which may affect upgrades and dependency resolution compared with earlier Percona Server releases. The APT packages are:

    • percona-server-client-core
    • percona-server-client-plugins
    • percona-server-client
    • percona-server-common
    • percona-server-server-core
    • percona-server-server
    • percona-telemetry-agent

Known issues

  • This release does not include the Percona Toolkit component. We will add it once a Percona Toolkit version compatible with MySQL {{vers}} becomes available.

  • In 9.7.x environments, the ProxySQL binlog reader can fail to initialize because it uses legacy commands, such as SHOW MASTER STATUS. Some internal counters also use outdated terminology. To address most terminology issues, enable the terminology_use_previous system variable on the database server. This workaround addresses only terminology compatibility and may not fix all failures.
