jrepin duly notes the release of Qt 4.8.0, and extracts from the announcement some of the key changes for developers: "Qt Platform Abstraction (QPA) restructures the GUI stack to enable easier porting of Qt to different windowing systems and devices. Threaded OpenGL enables us to render OpenGL from more than one thread concurrently. HTTP requests are now handled in a separate thread by default. The file system stack received some heavy lifting under the hood. The result is better I/O performance."
