I know about download section and I have installed 0.33 RC1 before. I just did not rush it now, because I have Steam version of Xenonauts and developers of community edition uploaded mod to Steam (at least they think so). It is esier to get updates (future hotfixes) using Steam than doing manually updates. Possibly I am lazy:) Anyway I am planning to play Xenonauts slightly later.
So I want to inform developers of community edition about possible problems with Steam deployment.
