# MySQL-wsrep 5.5.54-25.20 Release Notes

Codership is pleased to announce a new release of Galera Cluster for MySQL consisting of MySQL-wsrep 5.5.54 and Galera 3.20, wsrep API version 25.

This release incorporates all changes up to MySQL 5.5.54.

Galera Cluster is now available as targeted packages and package repositories for a number of Linux distributions, including Ubuntu, Debian, CentOS, RHEL, OpenSUSE, SLES and FreeBSD. Obtaining packages using a package repository removes the need to download individual files and facilitates the deployment and upgrade of Galera nodes.

This and future releases will be available from <http://www.galeracluster.com>. The source repositories and bug tracking are now on <http://www.github.com/codership> .

Notable bug fixes in MySQL-wsrep:

* Compilation with GCC 6 has been fixed (MW-332)

Notable fixes in Oracle MySQL Community Edition 5.5.54:

* Incompatible Change: The `mysqld_safe` script has been fortified against various security vulnerabilities

Known issues with this release:

* If using the Ubuntu 16.04 Xenial package, the server can not be bootstrapped using systemd. Please use the SysV init script with the 'bootstap' option to bootstrap the node. Note that a server that has been started that way can not be controlled via systemd and must be stopped using the SysV script. Normal server startup and shutdown is possible via systemd.
