Qt 5.1 - more than just a minor update
Just under six months after the release of Qt 5.0, a new version of the C++ user interface development framework has now been released. Qt 5.1 is not just a minor update focusing on improvements and performance, as originally intended, it also offers various new features, the most important ones being iOS and Android support, although these aspects continue to be classified as technology previews. According to the developers, however, the implementations can already be used in various scenarios.
Qt 5.1 has been released together with version 2.7.2 of the Qt Creator development environment. The components are available via a new online installer that will assist with automatic updating in the future. The developers have also released a new version of the add-in that provides integration with Microsoft's IDE Visual Studio. For the first time, Qt now works with Visual Studio 2012, and Windows users can choose ANGLE (Almost Native Graphics Layer Engine) or OpenGL.
With this release, the Qt developers have introduced a new model for managing serial ports (Qt SerialPort). Familiar from Qt 4.x, the Qt Sensors module for accessing sensor hardware has now become a Qt component again. It currently supports Android, BlackBerry, iOS and Mer/SailfishOS. The new Qt Quick Controls module offers a collection of reusable UI components for desktop applications. Qt Quick Layouts provides extra help with managing scalable user interfaces.
The open source, LGPLv2/GPLv3-licensed Qt is available to download for Linux, Mac OS X, Android (with Linux or Windows development environment) and Windows. Qt 5.1 is also available under a commercial licence.
