View the full changelog

Percona is glad to announce the release of Percona Server 5.7.19-17 on August 30, 2017. Downloads are available here and from the Percona Software Repositories.

This release is based on MySQL 5.7.19 and includes all the bug fixes in it. Percona Server 5.7.19-17 is now the current GA release in the 5.7 series. All software developed by Percona is open-source and free. Details of this release can be found in the 5.7.19-17 milestone on Launchpad.


Red Hat Enterprise Linux 5 (including CentOS 5 and other derivatives), Ubuntu 12.04 and older versions are no longer supported by Percona software. The reason for this is that these platforms reached end of life, will not receive updates and are not recommended for use in production.
New Features
Included the Percona MyRocks storage engine


MyRocks for Percona Server is currently experimental and not recommended for production deployments until further notice. You are encouraged to try it in a testing environment and provide feedback or report bugs.
#1708087: Added the mysql-helpers script to handle checking for missing datadir during startup. Also fixes #1635364.
Platform Support
Stopped providing packages for Ubuntu 12.04 due to its end of life.
Bugs Fixed
#1669414: Fixed handling of failure to set O_DIRECT
on parallel doublewrite buffer file.
#1705729: Fixed the postinst script to correctly locate the datadir. Also fixes #1698019.

#1709834: Fixed the mysqld_safe script to correctly locate the basedir.
Other fixes: #1698996, #1706055, #1706262, #1706981
