They did realy update or remade something (If they lost their HDD and didn't had a recent enouth backup that's probable), the text for the 9.2 video had a wrong font before and now it's the same as the other ones.
I think this was the longuest downtime they had, but as I though this was not related to the new update. Also they didn't even said not to update to 9.4 yet (But this is not realy usefull too, if you should not update to 9.3 you sould not do for higher versions ^^)
