I have now updated 0.7.x to this "newest one" 0.8.2 version.
There is some bugs of course..

1. I can't Open files (Ctrl+O) (bug detected!)
2. And fatal one is that if I use Pick Color(R) it will crash MyPaint and even ReBoot N900! if I play around with it.. and Example if you go another windows such Web Browser ... text field input does not work!

Pick Color(R) works now very different... because it do not pick color immediately you must touch screen to pick color?! This could be a bug or something because always I try to use Pick Color tool it will boot my device... so it is useless.

I think that MyPaint app. somehow reserve touchscreen pressure function itself or something

Yes.. Pick Color(R) is a BIG PROBLEM!

EDIT: another one.. now I can not type color Hex-code to the Color Triangle -> Colour name box? .. this was possible in old version. Same is true about other value boxes
