As fatalsaint said, PR1.3's major concentration is the QT mobility.
however, i noticed that it conprised of mainly bugfixes... no new features. However PR1.2 is quite a step to perfection... just a few more updates over time and ew OS would change the entire RoadMap for N900. thats what i believe at least.

Nokia never was too keen to notify users about updates...it still isnt... and crying over it actjally never worked out on nokias deaf ears... so why waste time...

this is the same situation repeating as the anticipation of PR1.2 when there were so many same type of threads with posts above 100. PR 1.3 will come when Nokia is done... Andre Klapper from maemo org and the Nokia developers must give the go signal... cryin over it just raises the temper...lol
