We are pleased to announce the immediate availability of MariaDB 5.5.22-rc. MariaDB 5.5.22 is the first release candidate (RC) release in the 5.5 series and follows the MariaDB 5.5.20-alpha and 5.5.21-beta releases. We hope to follow it up soon with a Stable (GA) 5.5 release.
MariaDB 5.5 is a merge of MariaDB 5.3 and MySQL 5.5 with some limited additional bug fixes. Please see the What is MariaDB 5.5 page for an overview of MariaDB 5.5.
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.
