interfaces, libraries and APIs that exist in MySQL also exist in MariaDB.

## Packaging Fixes

Numerous packaging fixes have been incorporated into this release of MariaDB\
Galera Cluster. In addition to the previously available RedHat, CentOS, and\
Fedora packages, Ubuntu and Debian packages are now available.

## Combined Repositories

The repositories for MariaDB and MariaDB Galera Cluster are now combined. The\
old MariaDB Galera Cluster Repository is being updated for this release but\
will go away in the near future, so if you are using that repository, please\
visit the [MariaDB Repository Configuration Tool](https://downloads.mariadb.org/mariadb/repositories/)\
and update your repository configuration file. If you feel comfortable editing\
your existing repo config file the change is pretty easy, just replace\
'5.5-galera' with '5.5'.

When using the repositories to install MariaDB Galera Cluster, the only\
difference between it and installing MariaDB is to specify the MariaDB Galera\
Server package instead of the MariaDB Server package and to install the Galera\
package. For example, on Ubuntu, after updating the mariadb.list file the\
following command will install MariaDB Galera Server:

```bash
sudo apt-get update
sudo apt-get install mariadb-galera-server
```

If MariaDB is already installed on the server the package manager will\
uninstall the appropriate packages prior to installing the MariaDB Galera\
Cluster packages.

See the [MariaDB 5.5.28a Changelog](https://mariadb.com/docs/release-notes/community-server/changelogs/changelogs-mariadb-55-series/mariadb-5528a-changelog) for full details\
of the many packaging and other fixes.

Thanks, and enjoy MariaDB Galera Cluster!
