Most importantly, MariaDB 5.1.62 and 5.2.12 include a fix for 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 as soon as possible.
Sources, binaries, and package downloads are available from our network of MariaDB mirrors. Debian and Ubuntu packages are available from our mirrored apt repositories. We have a sources.list generator for creating sources.list entries.
