Percona Server for MySQL 5.7.44-55 (2025-09-25)¶

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 fixes ported to 5.7 are the following:

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 binlog entry, resulting in a syntax error on the replica database.

Bug#37829550: Enhanced WAIT_UNTIL_SQL_THREAD_AFTER_GTIDS validations

WL#16949: Adds a new --commands option to the mysql client. This option, enabled by default, lets users 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.

Bug#37478594: A virtual column value may be incorrectly set to NULL on cascade update, which could lead to an unexpected server exit.

Non-security bug fixes¶

Bug#36784795: When the server ran with autocommit=OFF, the query rewrite plugin did not work correctly.

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

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.
