Today we have released Qt 4.8.4. Created together with the Qt Project, Qt 4.8.4 contains over 170 fixes and improvements compared to Qt 4.8.3. With important security fixes for Qt Network and Declarative modules the Qt 4.8.4 is a solid release we recommend all active projects to take into use. This release also contains the correct Digia copyrights as already reflected in the Qt repositories.
As a patch release Qt 4.8.4 does not add new functionality and keeps full source and binary compatibility with the Qt 4.8 series. Looking a bit into where these 170+ improvements have landed there are, for example:
41 fixes to Qt Gui module
13 Mac OS X specific fixes
8 Windows specific fixes
5 Linux/X11 specific fixes
36 QNX/Blackberry specific fixes
22 fixes for the tools
A detailed list of the fixes and improvements showing differences from Qt 4.8.3 can be found here.
Additionally I have good news for those who have been waiting for Windows 8 and VS2012 support. We have taken Qt 4.8.4 to a spin with Windows 8 and it runs quite well in the classic (desktop) mode on Intel hardware. Qt 4.8.4 can be built with Microsoft’s new VS2012 compiler, except for building WebKit. You can use the same pre-built VS2010 binaries with Windows 8 in addition to Windows 7.
Qt 4.8.4 is now tagged in the Qt Project repository. The source packages and stand-alone installers for Qt 4.8.4 are available for download at qt-project.org/downloads for open-source users, as well as via the Customer Portal for commercial licensees.
For commercial licensees there is also an online SDK update available for Qt 4.8.4. We are working to provide an open source SDK through the Qt Project after Qt 5.0.0 is out.
