Qt 4.5.3 is now available. 4.5.3 is a patch level release providing various bug-fixes over the 4.5.2 release that we issued in late-June. This release also includes new versions of the Qt SDK (2009.04) and the Qt Visual Studio Add-in (1.1.0).
For those using the public git repository, a "v4.5.3" tag will appear in the repository soon.
As always, your feedback on Qt is appreciated. If you have comments or bug reports, we'd love to hear from you. If you want to contribute to Qt, all the information you need to get started can be found at qt.gitorious.org.
