Guess it’s been a while since the last update. We’ve pushed out a pre-release (excitingly called 0.4.0_pre3327). The main reason for this is that it contains fixes for some long standing ATI and Windows bugs and the majority of bugs currently being reported affect 0.3.0 and have already been fixed in SVN.
It’s a pre-release because we’re not happy that it is of a high enough quality for a full release and it does not match the release criteria for 0.4.0. That being said it should at least run and be playable, there are known issues with the physics simulation (it’s been completely overhauled since 0.3.0).
