As a matter of fact, we are keeping currentish and testing new stuff.

Just about everyone's development systems and most third-party MediaWiki 
installations run on MySQL 5.x, and Domas (a Sun/MySQL support engineer) 
has been testing MySQL 5.x in limited runs within the Wikimedia cluster 
over the last year or so. MediaWiki's functionality on MySQL 5.x is well 
known.

In the meantime, our primary production machines are running time-proven 
MySQL 4.0.x with up-to-date stability and performance patches maintained 
by Google -- fixes which have not yet all been rolled back to mainline 5.x.
