MariaDB 5.5.23 GA Stable Released
MariaDB officially has released it’s MariaDB 5.5.23 GA MySQL server about 2 weeks ago. Still waiting on an RPM binary version for download while they work out the buildbot/rpm building issues. But you can download the source tarball and Debian repository versions.
Includes MariaDB 5.3.6
MariaDB 5.5.23 includes MariaDB 5.3.6, which, among other things, fixes a bug that under certain rare circumstances allowed a user to connect with an invalid password. This is a serious security issue. We recommend upgrading from older versions of MariaDB 5.5 as soon as possible. See the MariaDB 5.3.6Release Notes and Changelog for more information.
