Bug 1: i cant seem to find the release / changenotes

Ok, aside from that, i updated to PR 1.3 this weekende, and i must say it was a bad decision. I should have sticked to "never change a running system".

I mean, yes it works. But i have some major stability issues (Had to reboot my N900 twice in the last three days because it crashed, thats unusual) and it seems as if something change to "it will work, but it may take a while" to "either its fast or it wont work at all".
Its like when im multitasking, an app suddenly will start to show strange things on the display (like a half built windows) and the crashes. That never happend to me before. Everything feels less stabil.

So, what did "THEY" (like in the X-Files) change?
