Qt 6.4 Beta Released

We have released the first Qt 6.4 Beta today. During the beta phase we provide multiple beta releases via the online installer. Target is to release the Qt 6.4.0 at the end of September 2022. Please try out the beta releases and send us feedback.

Qt 6.4 adds three modules compared to Qt 6.3 and of course brings multiple new features and improvements within the existing modules. New modules Qt 6.4 are Qt HTTP Server and Qt Quick 3D Physics, both available as a technology preview. We also restore Qt Text to Speech module, which is now updated and ported to Qt 6.4. Additionally to these, we have a new Qt VNC Server module providing remote UI functionality for Qt 6.4. The new Qt VNC Server module is available for selected commercial licenses.  

There are many important and exciting features within existing modules coming with Qt 6.4 as well - such as iOS style for Qt Quick Controls and spatial audio support for Qt Multimedia - and a lot more. One highly requested item is support for Qt for WebAssembly we have been working on via multiple technology previews in earlier Qt 6.x releases. With Qt 6.4 we are fully supporting Qt for WebAssembly as a new platform. 

For more information about the Qt 6.4 release, please follow this blog and check out our documentation snapshots. We have already blogged about some of the new items coming with Qt 6.4 and will be writing more posts around Qt 6.4 in the coming months. 

After the first beta released today, we will push out multiple new beta releases using the online installer. With this approach, it is easy for users to test the new features and provide feedback. We are not planning to publish separate blog posts for the subsequent beta releases and release candidate(s). In addition to binaries, source packages of each beta release are also available for those who prefer to build themselves.

I hope you will try out the Qt 6.4 Beta releases and provide feedback to help us identify what we need to improve for the Qt 6.4.0 release targeting end of September. For any issues you may find, please submit a detailed bug report to bugreports.qt.io. When filing a bug report, remember to mention which beta you found the issue with and check the list of known issues. You are also welcome to join the discussions in the Qt Project mailing lists and developer forums.
