Most of the activities lately have been around Qt 5, but rest assured – Qt 4.8 is still very much alive as well! I am extremely pleased to announce that we have released 4.8.3 today together with the Qt Project. Since the previous release, over 200 fixes and improvements have been made, making it worthwhile for most Qt 4.8 users to migrate to this new version. Furthermore we have now included official support for VxWorks, developed together with Wind River.
In addition to VxWorks support, highlights of 4.8.3 include changes to better support Mac OS X 10.8 and QNX, as well as new WebKit (2.2.3). We have made significant improvements to many modules, including QtCore, QtGui and QtNetwork.
VxWorks is a leading real-time operating system found in about one billion embedded systems in industries as diverse as underground railways and outer space! Qt is an excellent tool to create interactive and dynamic user interfaces for VxWorks and I am really happy to now declare the combination an officially supported platform for commercial Qt licensees. Many of the improvements are also made available to open-source Qt users, though VxWorks itself is not available under an open-source license.
Qt runs nicely with VxWorks on a large variety of hardware, including embedded ARM and x86 processors. Both DKM and RTP modes are supported allowing the leverage of a wide array of different Qt functionality including OpenGL accelerated graphics, Qt Quick and WebKit to name a few examples. Naturally the basic Qt modules are also well supported for ease of programming and portability.
More information and a video can be found from our earlier blog post on VxWorks.
A detailed list of the fixes and improvements, as well as a change log showing differences from Qt Commercial 4.8.2 can be found here.
As agreed with the Qt Project, Digia has also packaged and tested the open-source version of Qt 4.8.3, which feeds from the Qt Project 4.8 branch. We will keep providing patch releases to 4.8 as long as needed, we currently anticipate at least two more patch level releases. Qt 5 provides high compatibility with Qt 4 and we recommend all Qt users to migrate their active projects to Qt 5.0.0 when the final version release is available.
Qt 4.8.3 is now available as an update for all commercial SDK and stand-alone installer users via the Qt Commercial Customer portal .
We have also updated the SDK maintenance tool, so please make sure you install that update first before installing 4.8.3.
If you are not yet using the Qt Commercial SDK, you can try it out and get the SDK installer from the Qt Commercial Customer Portal. We also have tagged the Qt 4.8.3 release to the Qt Project repository.
If you have any questions, please don’t hesitate to contact us via the customer portal or the contact form.
