Qt Creator 2.5 Release Candidate has been released today. Since the beta release a lot of bug fixing (180+) has been done, including some crashes and some regressions in the C++ code model handling. Thanks to all who contributed to these 180+ fixes. Full changelog is available here plus there is also a new (experimental) plugin for direct support of autotools project. Qt Creator 2.5 RC can be downloaded from here.

The Qt SDK 1.2.1 is now available for download. It brings increased stability to the Qt SDK 1.2. The updated SDK includes Qt 4.8.1 desktop installers for Mac and Windows in addition to Qt source packages. Qt 4.8.1 is the first patch release to the 4.8 series with over 200 functional improvements to the desktop and embedded platforms. The focus of the error corrections, made by primarily by Digia, has been on desktop and embedded platforms with a large number of fixes focussed on QtCore, QtGUI and QtNetwork. For more details please see: Qt 4.8 library release.

Increased ease targeting Nokia N9 through bug fixes and added functionality: The added functionality in the Qt SDK 1.2.1 relates mainly to improved runtimes for testing. The Simulator now supports both landscape and portrait orientations. In addition, the Qt Quick Components in the Simulator have been upgraded to use the same version as is on the device. There are now three separate QEMU images - one each for PR1.0, PR1.1 and PR1.2.

In the last weeks there have also been some other updates that will help you with your Nokia N9 development:

• An example application showcasing key Harmattan APIs. The application shows how to utilize Qt Mobility interfaces (e.g. maps, multimedia and sensor data) in applications.


• The Harmattan developer library and UX documentation have been updated. The latter is available online, and the former is also provided within the Harmattan target for Qt SDK.

Other interesting projects:

• Shader effects using QML. Have you noticed / tested the Qt.labs.shaders plugin yet? It ships with Qt 4.7.4 onwards, making it easier to make graphical effects with QML. A Qt 4 version of the demo is available here for desktop and Nokia N9.


• For developers looking at 3D technologies, Qt 3D 1.0 for Qt 4.8.1 has also been released today. Qt 3D will be providing OpenGL accelerated 3D content defined in QML. Qt 3D packages for Harmattan and Symbian are not pre-built and you'll have to build them yourself. Nokia N9 build instructions can be found here.
