We are pleased to announce the immediate availability of MariaDB 5.5.20-alpha. MariaDB 5.5.20 is the first Alpha release in the 5.5 series. We hope to follow it up soon with a beta 5.5 release.

MariaDB 5.5.20-alpha is a merge of MariaDB 5.3 and MySQL 5.5 with some limited additional bug fixes. This is the first 5.5-based release, and we are releasing it now, intentionally without any extra features (and with it missing some planned features) to get it into the hands of any who might want to test it. Extra features planned for MariaDB 5.5 will be pushed into future releases.

As with any alpha release, MariaDB 5.5.20-alpha should not be used on production systems.

The Release Notes page has some notes on the release. There is also a Changelog available for those who are interested.

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 created a sources.list generator for creating sources.list entries.
