Percona Server for MySQL 5.7.44-55 has been released

Percona Server for MySQL 5.7.44-55 has been released on Thursday, September 25, 2025.

Try it out using the Installation guide.

This release is part of Percona’s MySQL 5.7 Post-End-of-Life (EOL) support program. This program provides critical updates and ensures the stability for businesses relying on MySQL 5.7 beyond its official EOL. Paying customers can access the full release, including pre-compiled binaries, through our private repository. Community members will be able to build the release from publicly available source code, which will be released on a quarterly basis.

This release includes security and non-security fixes ported from the 8.0 version.

A replication bug was fixed where a semicolon in a MySQL-specific comment could cause an incomplete entry in the binary log, which would then lead to a syntax error and replication failure on the replica. This ensures better consistency between the source and replica databases.

The WAIT_UNTIL_SQL_THREAD_AFTER_GTIDS validations have been enhanced to improve the reliability and correctness of replication threads, providing more robust synchronization.

A new --commands option has been added to the mysql client. This feature allows users to disable client-side commands, which enhances security by preventing the execution of unintended commands, particularly in non-interactive mode.

A fix was implemented to prevent an unexpected server exit. This issue occurred when performing range queries on a table that included a prefixed BLOB or TEXT column within its index.
