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 It was very outdated version - any linux distribution has a 5.x for a long time.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. Dmitriy
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.
