内容:
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).
Content
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:
Qt Platform Abstraction (QPA)
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.
Threaded OpenGL support
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.
Multithreaded HTTP
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.
Optimized file system access
The file system stack received some heavy lifting under the hood. The result is better I/O performance, achieved by reducing the number of system calls performed for I/O and by better use of cached data, when available. The improvements in performance can be seen across all platforms.
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.
Downloads
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.

这么多人实在太了不起了，开发速度这么快，对于新出来的东西，很期待使用一下。看看和以前版本有多大质的变化。

不知道Qt4的最后一个版本会是啥呢……
真心不知道将来Qt5来了之后要不要往那个方向转……
另外听朋友说用mingw32和mingw-w64自己编译失败了，并且明明之前的版本都可以的。不知道这些方面的资料该去哪找呢？

4.8.0很奇怪，静态编译ok，动态反而出错。
