We have two parts of updates.
The 1st part is DB AS Library. We introduced FastArmature to great improve performance about 300% in Starling framework. The secret of FastArmature is that it remove the animation mixing feature and add animation cache (back from 3.0). You can download it here.
The 2nd part is DB Pro the animation editor. We add Curve Editor, Onion skin tool and IK pose tool. You can download it here.
