Just like with PR1.1, N950 is getting the newest firmware release first. PR1.2 is already official announced on Nokia’s Developers page to be available “shortly” for N950. We already know PR1.2 to bring copy & paste to the browser, iOS styled folders on home screen, gallery and camera changes, plus many under the hood changes we know nothing about. Be free to check the leaked PR1.2 pictures from the link.
We will be shortly releasing a developer edition of MeeGo 1.2 Harmattan 1.2 beta (feel free to crack a joke v 1.2 here) to developers with Nokia N950 Developer Device. The goal of this early access release is to enable developers to verify that their applications do not exhibit any regressions in the new platform version.
This release will be available as a one-click-flasher for Nokia N950 Developer Device. In other words, in order to participate in this beta you need to already have a Nokia N950 Developer Device.
We have done our best to ensure full binary compatibility from Harmattan 1.0 and 1.1 (and 1.1.1 Arabic) to Harmattan 1.2, but we want to offer developers the opportunity to test and verify their apps on the real thing before actual global roll out of the consumer release. There will be also small changes between beta and final consumer release, mostly focusing on ensuring release robustness and performance.
There is at least one known change in the Harmattan 1.2 (and 1.1.1 Arabic) that is impacting developers: The system font change. See blog posts The default font will change — to bigger and better (18th Dec 2011), Font change part 2: playing with the line height (21st dec 2011) and Font change part 3: Flexible UI layouts (5th Jan 2012) for more details.
