Humm... It seems like they are all several months old?
As you can see, Kelson recently focused on other things like the "wp1" releases. The ZIM dump production is now orders of magnitudes easier than it was years ago with the dumpHTML methods, so if you have a cogent need for a more recent dump you can tell Kelson (cc) and he'll probably be able to help.
Feel free to send patches as well. ;-) https://sourceforge.net/p/kiwix/other/ci/master/tree/mwoffliner/
