I did initially post an update (v8.0.7) but I deleted it because it broke way more than it fixed. Factorio server might still believe that there should be an update? But v8.0.6 is the latest official update.
EDIT: I've uploaded v8.0.8 as the latest version. Hopefully shouldn't affect anything, unless you were running bob's assembling machines mod without using bobs intermediates mod.
