Version 0.8.10 is out, which is bugfix release with some additional improvements:

• the text mode (which is no longer white on white - one bugfix) combines very short lines to longer ones
• each annotation and the eraser have their own key now (N: note (“Text”), D: draw freehand(“Ink”), E: eraser), but you have to switch to annotation mode with A (or the pen button in the main menu) first
• you can remove single entries from both histories (recent files and in-document) without clearing the entire list

Now there's also a Windows version (see gitorious).
