Release Notes: Declarative UI development was introduced with Quick (Qt UI Creation Kit), which includes the Qt Markup Language (QML) as a language to describe and construct GUIs, and QtDeclarative as the engine and to combine C++ and QML elements. The new Network Bearer Management API was added in QtNetwork, e.g. for the discovery of system and interface availability. The performance of QtWebKit was massively improved, with a new backing store and support for accelerated compositing. Many minor enhancements and bug fixes were made throughout the libraries.
Release Notes: The new Qt Quick Controls and Qt Quick Layouts modules finally offer ‘widgets’ for Qt Quick. Qt Sensors has now been added to Qt 5.1, supporting Android, Blackberry, and iOS. Qt Serial Port lets you interface with physical and virtual serial ports of your device to allow easy access to your hardware peripherals through a common cross-platform API. Qt X11 Extras provide you direct access to screen information on platforms running the X server.
Release Notes: Qt 5.0.2 brings over 600 improvements compared to Qt 5.0.1. Qt Creator 2.7.0 is included in the release package. You can now easily skip modules in configure when building Qt yourself. Static linking now works correctly for the Qt libraries.
Release Notes: This version represents a major overhaul of the C++ GUI programming framework. Key benefits include graphics quality improvements, higher performance on constrained hardware, cross-platform portability, support for C++11, HTML5 support with QtWebKit 2, a vastly improved QML engine with new APIs, and ease of use and compatibility with Qt 4 versions.
Release Notes: This release adds over 100 functional improvements, updates WebKit to version 2.2.2 and libpng to version 1.5.10, and adds 30 improvements to documentation and tools.
Release Notes: Qt Platform Abstraction (QPA) restructures the GUI stack to enable easier porting of Qt to different windowing systems and devices. Threaded OpenGL enables rendering OpenGL from more than one thread concurrently. HTTP requests are now handled in a separate thread by default. The filesystem stack received some heavy lifting under the hood. The result is better I/O performance.
