The target of the Qt SDK 1.1 is to easily get started with Qt Quick development on Symbian, Maemo5 and the desktop.
Specifically this means:
* Qt Creator 2.1RC, which includes the first iteration of tooling support for Qt Quick.
* Qt 4.7.1 for Symbian (Symbian^1 and Symbian^3) is bundled in the toolchain and is also available as sis packages to install on your phone.
* Qt Mobility 1.1 for Symbian targets (both Symbian^1 and Symbian^3) adding many new features and fixes
* The N900 target allows development with Qt 4.7
* Qt Simulator uses Qt 4.7.1 as well as Qt Mobility 1.1 as a basis for development.
The new Qt SDK 1.1 Technology Preview enables developers targeting desktop platforms to use the same setup, features and environment as developers targeting platforms. This eases the migration of desktop applications to mobile platforms.
Lots of feedback has been received from developers about the Symbian support level in the Nokia Qt SDK 1.0, specifically that it was not possible to use native APIs. In this case developers were asked to install the platform SDK, which required manual efforts. It has been simplified by refactoring the Symbian toolchain parts completely, allowing you to enable the usage of native APIs for Symbian^3 optionally. This can be done via the installer or the maintenance tool. Further features will be coming in this area in coming releases.
In addition to this, supplementary packages have been added or received updates. The Nokia Qt SDK 1.0 already had the remote compiler integrated, which allows compilation of your project on a remotely hosted server. Several improvements made it into the latest version, also allowing compilation based on the updated Qt and Qt Mobility versions.
The Notifications API describes a unified framework to create a connection to a server for receiving notifications, of course based on Qt. It is designed to use a minimum of data bandwidth as well as behave in a battery friendly manner, as is required by today's smart phones. This feature is located in the experimental section of the SDK and will finalize soon. For more details, follow this link.
