information on each push, see the [MariaDB Galera Cluster 5.5.37 Changelog](https://mariadb.com/docs/release-notes/community-server/old-releases/mariadb-galera-cluster-releases/mariadb-galera-55-changelogs/mariadb-galera-cluster-5537-changelog).
## Notes about this release
* MariaDB Galera Cluster 5.5.37 includes [MariaDB 5.5.37](https://mariadb.com/docs/release-notes/community-server/old-releases/5.5/5.5.37) with Codership\
additions (`lp:codership-mysql/5.5` till revision `3980`) and [Galera 25.3.5](https://codership.com/content/using-galera-cluster).
* This version of MariaDB Galera Cluster supports `wsrep` API v25 which means\
MariaDB Galera Cluster can be used with either a 25.2.x or 25.3.x\
Galera `wsrep` provider. A 25.3.x `wsrep` provider is included in the\
MariaDB repositories and both 25.3.x and 25.2.x wsrep providers are available\
on the downloads page.
* This release includes a new method for snapshot state\
transfer, `wsrep_sst_xtrabackup-v2`. This method of state snapshot transfer\
can be configured using the `--wsrep_sst_method=xtrabackup-v2`\
option. Its use requires [Percona Xtrabackup](https://app.gitbook.com/s/SsmexDFPv2xG2OTyO5yV/clients-and-utilities/legacy-clients-and-utilities/backing-up-and-restoring-databases-percona-xtrabackup/percona-xtrabackup-overview) (>= 2.1.6) and other software packages\
like socat, nc, and tar.
See the [MariaDB 5.5.37 Release Notes](https://mariadb.com/docs/release-notes/community-server/old-releases/5.5/5.5.37) and [Changelog](https://mariadb.com/docs/release-notes/community-server/changelogs/changelogs-mariadb-55-series/mariadb-5537-changelog) for more information on the changes in\
MariaDB.
Note: If Galera 25.2.x and 25.3.x are both being used in the cluster, MariaDB\
with Galera 25.3.x must be started with`wsrep_provider_options='socket.checksum=1'` in order to make it backward\
compatible with Galera v2. Galera wsrep providers other than 25.3.x or 25.2.x\
are not supported.
Important: wsrep\_sst\_rsync (sst script) in MariaDB Galera Cluster 5.5.37 uses `lsof` which might not be installed by default on some linux distributions. It has to be installed if the `wsrep_sst_method` is set to `rsync` (default). Future MariaDB Galera Cluster releases will address this by adding a dependency on lsof.
## Bug Fixes
This release contains fixes for bugs, compiler errors/warnings and improvements\
in existing scripts.
A list of all the bugs fixed can be found in the [changelog](https://mariadb.com/docs/release-notes/community-server/old-releases/mariadb-galera-cluster-releases/mariadb-galera-55-changelogs/mariadb-galera-cluster-5537-changelog).

* [CVE-2014-2436](https://cve.mitre.org/cgi-bin/cvename.cgi?name=CVE-2014-2436)
* [CVE-2014-2440](https://cve.mitre.org/cgi-bin/cvename.cgi?name=CVE-2014-2440)
