Announcing Galera Cluster 5.7.18, 5.6.36 and 5.5.55 with Galera 3.21. Improvements to IPv6 Support, Bug Fixes and Changes to Repositories Structure

Codership is pleased to announce a new release of Galera Cluster for MySQL
consisting of MySQL-wsrep 5.7.18, 5.6.36, 5.5.55 and Galera 3.21, wsrep API
version 25.

Changes to Repositories Structure

With the new release the repository structure is changed to allow for
existence of all of the wsrep-patched mysql versions currently supported:
5.5 through 5.7.

Thus the repository layout requires from the user to adjust his or her
repository configuration to accomodate those changes. In order to have the
MySQL-wsrep and Galera library installed, one would need to add the following
repositories:

1. Galera-3 repository for galera library:
e.g. http://releases.galeracluster.com/galera-3/DIST/

Here DIST is Linux distribution (ubuntu, centos, …).

The latest version of Galera for FreeBSD is available in FreeBSD Ports
