Hi!
What test wiki other than one's own runs the current SVN version?
mediawiki-l@ ?
Even test.wikipedia.org is "only" at r48811.
test.wikipedia is staging ground, not mediawiki development testbed.
How does one confirm a problem is not just local before posting a bug without waiting a few days for test.wikipedia.org to catch up?
by employing such things as analysis and common sense.
