Qt SDK 1.1 RC released

Qt SDK 1.1 Release Candidate released. This is a major step towards the final Qt SDK 1.1, building on the beta we released a couple of weeks ago. The final Qt SDK will allow you to submit your Qt 4.7 based applications to the Ovi Store.

Summarizing the most important updates compared to the beta:

• Qt 4.7.3 is included for Desktop and Symbian
• Update to Qt Mobility 1.1.2
• Qt Assistant added as separate package (due to developer request)
• Installer can use system proxy on Linux
• Notification API moved from experimental to “Additional APIs”
• Several fixes for the Qt Simulator
• Several fixes for the installation/updating workflow

You are suggested to read the important article about that Qt 4.7 will not be supported for S60 3rd Edition. Please note that you are still able to create Qt applications for those targets based on Qt 4.6.

Qt SDK 1.1 beta released

Qt SDK 1.1 beta released, with Qt 4.7.2 a lot of improvements and fixes for Qt Quick have been published. Qt Mobility 1.1.1 includes updates for the supported platforms. Qt Creator 2.1 will allow you to create and design your QML applications from within the IDE nicely.

What has been missing so far is a nice and convenient way to get the whole package, namely the SDK.

The Qt SDK describes a merger between the Nokia Qt SDK, which provided a development environment for mobile targets, and the Qt Desktop SDKs. This allows you to develop applications for all platforms, which Qt supports. Compared to the Technology Preview we have included a significant amount of updates, namely:

• Qt 4.7.2 for Symbian ^1 and Symbian ^3
• Qt 4.7.2 for the Desktop
• Qt 4.7.2 for the Qt Simulator
• Qt Mobility 1.1.1 for Symbian^1, Symbian^3 and the Qt Simulator
• Qt Creator 2.1 final
• Qt Simulator 1.1 beta
• Updates to the Symbian Complementary package, providing the toolchain and build tools for the Symbian platforms

Qt Creator 2.1.0 released

With a few important fixes since the 2.1.0 release candidate, including adaptions of the mobile application project wizards and deployment related files, and updated documentation. Together with the Qt SDK 1.1 beta, Qt Creator 2.1.0 is released to provide a great experience.

The overall agenda for Qt Creator 2.1.0 was enhanced Qt Quick and mobile application support. And of course it got lots of improvements in all other areas as well.
