Known bugs

Seperate DefResolU for render (for curves) does not work for objects that are inside groups
Groups appended from other files need to cycle group editmode (SHIFT-TAB SHIFT-TAB) first before they are drawn
Groups can only be edited in-place if they are unscaled or uniformly scaled and unrotated, otherwise they will be edited in their untransformed state
The recent files popup (CTRL-O) doesn't work on windows
High shadow resolutions only work with the unified renderer
Alpha 1.0 for shadow effects still isn't totally opaque
Shadow effects will always render in black regardless of the chosen colour
If an object has several materials with different alpha settings, the alpha settings of the first material will be used for all materials in the preview (it will be OK in the render, though)
Underlines in text objects use an incorrect material index
After dissolving a group, a manual redraw is needed until the group's former members are drawn
Pages do not work for groups - they will appear anyway
The "Arrow" primitive is broken
