Tizen releases some code

Nokia is still releasing firmware updates with bugfixes (PR 1.1) and new features (PR 1.2, rumoured to be out soon). They have promised to keep supporting the N9 for "years" or something like that.

There are no plans to release new devices on the Meego 1.2 Harmattan platform or its successors ever since Elop took over and decided to bet Nokia's future on Windows Phone. That's why most reviewers call the N9 dead on arrival, I believe. It doesn't stop me from enjoying mine ;)
