Percona Server for MySQL 5.7.44-55 (2025-08-20)¶

This release is part of Percona’s MySQL 5.7 Post-End-of-Life (EOL) support
program. It provides critical updates and ensures stability for businesses
relying on MySQL 5.7 beyond its 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 8.0 is recommended, but support for MySQL 5.7 will continue.

Release Information¶

Percona Server for MySQL 5.7.44-55 builds on MySQL 5.7.44 Community Edition,
adding enterprise-grade features and security enhancements from Percona.

Security fixes¶

The following is the final list of fixes which will be ported to 5.7

Bug#37117875: When the delimiter is changed from the default and a SQL statement includes an unquoted semicolon inside a MySQL-specific comment, the statement executes successfully on the source database. However, this operation causes an incomplete entry in the binlog, which results in a syntax error on the replica database.

Bug#37829550: Enhanced WAIT_UNTIL_SQL_THREAD_AFTER_GTIDS validations

Backport of WL#16949 to 8.0.: A new --commands option has been added to the mysql client. This option, which is enabled by default, allows users to disable client-side commands when running in non-interactive mode.

Bug#31360522: An unexpected server exit may occur when performing range queries on a table that includes a prefixed BLOB or TEXT column within its index.

Non-security bug fixes¶

Bug#36784795 : When the server runs with autocommit=OFF, the query rewrite plugin fails. The plugin’s rule-reloading thread inherits the autocommit=OFF setting and attempts a statement commit, which does not save changes in this mode. As a result, any rule modifications are lost when the thread exits.

Bug#37572191: If preserve_comments is turned off, the server won’t allow hints that contain # or -- inside comment blocks. The fix was already provided in Percona Server for MySQL 5.7.44-54, this update fixes the test case.

Bug#37765153: To allow Debian/Ubuntu builds to run without root privileges, we removed the file ownership changes from the installation commands in our packaging scripts. These commands were previously run as the root user (or with fakeroot) and are no longer necessary or recommended.
