Some of you are bound to have realized that there is a new update for the N900, PR1.3. This is primarily a consumer update containing many tweaks and improvements to the N900 user experience. It also aligns the Qt application and UI framework with the planned version for the MeeGo 1.1 platform (Qt 4.7).  Qt Mobility 1.0.2 APIs for mobile development are also included.

Software development using scratchbox for the new platform will be supported right away.  For those using the Nokia Qt SDK, we have tested Qt 4.6 applications on PR1.3 and did not encounter any major problems, so you can continue to distribute apps developed with the current toolset. Support for new N900 apps with the Qt4.7 framework will be available with a Nokia Qt SDK update that will be available soon.   Until then, Ovi Store will accept applications built using Qt4.6.

Qt 4.7 comes with Qt Declarative libraries and QML support. This cutting edge technology allows the fast creation of impressive application UIs.  It also supports interaction with C++ objects, allowing developers to create dynamic UIs in QML and link them to background C++ code.  There have been many examples of Qt Quick already posted at maemo.org and at qt.nokia.com.  Full Qt Creator support for Qt Quick development will be available when Nokia Qt SDK 1.1 is released.
