Qt has reached another important evolutionary milestone today. We are very proud to announce that Qt 4.8.0 has now been released. Many people have worked long and hard to deliver Qt 4.8.0. Today that hard work reaches final release maturity, and we are celebrating!
Featuring Qt Platform Abstraction, threaded OpenGL support, multithreaded HTTP and optimized file system access, Qt 4.8.0 can be downloaded as binary or source packages (Qt Download Page).
Those of you that have been testing and using Qt 4.8 through its earlier stages will know the key benefits it brings. If you haven’t been following it, here are some key features that are new in Qt 4.8.0:
QPA restructures the GUI stack to enable easier porting of Qt to different windowing systems and devices. More info on: Lighthouse has grown up now.
Enables those of us that are not OpenGL-ninjas to render OpenGL from more than one thread concurrently. More info on: Threaded OpenGL in 4.8.
HTTP requests are now handled in a separate thread by default. This should make application guis smoother, as networking will no longer use the main event loop.
Qt 4.8.0 ships with QtWebKit 2.2.1. More details of the major changes can be found in the Qt 4.8 beta blog post.
The source and binary packages for Qt 4.8.0 can be downloaded from the Qt Download Page. The source code can also be found in the public repository, where the “v4.8.0″ tag matches the released packages. Please note that the documentation has been moved to Qt Developer network, as part of moving Qt to the Qt Project.
