You probably won't see much in the way of updates until all the jobs ahve completed; they are in progress now.

Hello dumps users!

You may have noticed that a number of wikis have had dumps failures on the flow dumps step. The cause is known (a cleanup of mediawiki core that didn't carry over to the extension) and these jobs should be fixed up today or tomorrow.
