Percona Distribution for MySQL 8.4.10 using Percona Server for MySQL has been released

Percona Distribution for MySQL 8.4.10 using Percona Server for MySQL has been released on Tuesday, June 30, 2026.

Try it out using the Installation guide.

Builds and packaging

  • Percona Server for MySQL releases include a mixture of PGO and non-PGO builds. Where Profile-Guided Optimization (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 you receive for your platform.

Known issues and limitations

  • In 8.4.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 Some internal counters also use outdated terminology.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.
