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.
Release Notes: This version introduces new features like Qt Quick 1.1 (with right-to-left support, improved image caching, and text input improvements: support for split-screen virtual keyboard, and Pinch Area to provide a declarative API for handling touch input) and the QML Shaders plugin (embed OpenGL shader effects in QML apps). There are also additional improvements for Symbian and a lot of bugfixes.
