Good to hear!
My extension was broken with 4.0.40 (nested selects, perhaps). It was
very outdated version - any linux distribution has a 5.x for a long
time. Probably MediaWiki core will drop the compatibility, too.

Don't be so eager.
Replication will break in funny ways when a 5.1 master will get a v5
event. In the best scenario, all mysql4 slaves stop replicating at once,
overloading the 5.1 ones and leading the wiki to a halt. Domas ends up
removing the offending statement with a hex editor or upgrading all the
slaves in a hurry.
Do we have at least one 5.1 slave per 5.1-mastered pool ?
Domas said that each cluster was "fully 5.1", meaning all masters and
slaves are running 5.1.
