MariaDB 5.5.20 Alpha MySQL Server Released
MariaDB 5.5.20 Alpha MySQL Server has been released based on MySQL 5.5 with merging of MariaDB 5.3 with MySQL 5.5. Full MariaDB 5.5.20 Change Log. Full description of MariaDB 5.5 here.
MariaDB 5.5.20 is an Alpha 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, 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 subsequent releases. Do not use alpha releases on production systems.
