Nonsense.
I have started my map when 2.07 was the latest version.
Since it is very likely that players will use 2.08 for my mission (and I anticipate the same goes for The Painter' Wife"), I switched my 2.07 mission to 2.08 beta as well.
Unfortunately, 2.08 shows severe non-mapping problems I would have to fix for a 2.08 release (especially when it comes to AI behaviour) anyway.
