Code review comment for lp:~hrvojem/percona-xtradb-cluster/rn-5.5.37-25.10

+Based on `Percona Server 5.5.37-35.0 <http://www.percona.com/doc/percona-server/5.5/release-notes/Percona-Server-5.5.37-35.0.html>`_ including all the bug fixes in it, `Galera Replicator <https://launchpad.net/galera/+milestone/25.2.8>`_ and on `Codership wsrep API 5.5.34-25.9 <https://launchpad.net/codership-mysql/+milestone/5.5.34-25.9>`_, |Percona XtraDB Cluster| `5.5.37-25.10 <https://launchpad.net/percona-xtradb-cluster/+milestone/5.5.37-25.10>`_ is now the current stable release. All of |Percona|'s software is open-source and free.

This is based on Galera 2.10 and wsrep API - 25.10, however, no need to mention https://launchpad.net/codership-mysql/+milestone/5.5.34-25.9 (I think we already referred to this in previous PXC 5.5 release), but while mentioning galera 2.10 (mention that it includes fixes in https://launchpad.net/galera/+milestone/25.2.9).
