I've cleaned up our haks somewhat, removed some legacy stuff, but - more importantly - added a metric ton of great creatures by importing the Project Q creatures hak.
The updater isn't deleting old files automatically, because that would break old FWN-sourced toolset modules, but if you don't need any of that, you can safely delete:
(I've also removed some old and broken horse phenotypes from our old _item.hak.)
As to downloads, we're adding
hak/q_creatures.hak, which is another 383MB or so on disk, and thanks to rsync you can expect only 160MB of actual transfer. Actual net disk usage as a consequence is minus 870MB if you delete all of the above.
There's some issues remaining w.r.t. additional riding phenotypes - we'll fix those as we go along.
I've also pushed a new catflap release that is a bit more verbose about expected disk usage.
