Tuukka Turunen Today we have released Qt 4.8.5 bringing close to400 improvements over the previous release in the Qt 4.8 series,including important security updates and error corrections. As a patchrelease it does not add new functionality and maintains fullcompatibility with the Qt 4.8.x releases.Qt 4.8.5 provides overall close to 400 improvements, for example:
- 35 fixes to Qt Core module
- 65 fixes to Qt Gui module
- 21 Mac OS X specific fixes
- 15 Windows specific fixes
- 8 Linux/X11 specific fixes
- Webkit upgrade to 2.2.4 (minor improvements)
- Change all shmget calls to user-only memory (security)
- Several important fixes for the VxWorks port in the Qt Enterprise version, see blog post for details on VxWorks improvements
A detailed list of the fixes and improvements in Qt 4.8.5 compared to Qt 4.8.4 can be found
here.
Qt 4.8.5 is now tagged in the Qt Project repository. The sourcepackages and stand-alone installers for Qt 4.8.5 are available for
download from the Qt Project for open-source users, as well as via the
Customer Portal for Qt Enterprise licensees. For Qt Enterprise licensees there is also an online
SDK update available for Qt 4.8.5.
The new online installers used in conjunction with Qt 5.1 areequipped to handle also Qt 4.8 content, but some ‘housekeeping’ isneeded before it can be included. We are planning to add Qt 4.8.5 to beavailable through the new Qt Enterprise and Qt Open-source onlineinstallers later, most likely around September.
Qt 4.8 is still actively used, and we are providing patch releases toit also after Qt 4.8.5. Many users have already taken Qt 5 for a spinand with the new Qt 5.1 available soon, we encourage also the others todo so. But there is no panic to jump away from Qt 4.8 immediately. Itremains supported and you can take the steps towards Qt 5 according toyour own schedule. With high degree of source compatibility, we want tomake switching to Qt 5 smooth and straightforward.
