MariaDB 5.5 is now inside of OpenBSD, the free, functional & secure OS. The work started a few weeks ago, and now you can get MariaDB via the ports tree. And yes, it will replace the current MySQL 5.1 that ships in the next release.
#ILOVEFS A charming reminder from the @fsfe that Free Software is a lot about <3. So here's to my early Free Software loves: @official_php, @mysql (now @mariadb_org), @TheASF, #perl (& @TimToady's wonderful States of the Onion), #vim, @Linux, and - of course - @fsf. Love you all.
