In 2016 we covered a few times the work being done to revive Qt WebKit while coming out this week is a fresh "technology preview" release of the Qt WebKit code for those interested in this alternative to the Chromium-based Qt WebEngine.
New to QtWebKit Technology Preview 5 is support for accelerated WebGL and then on Windows platforms is now MinGW compiler support. This improves feature parity for QtWebKit while the developers are still working on restoring QML API support.
Binary builds of this new QtWebKit module build are available for Qt 5.8. Qt developers potentially interested in this module can learn more via the mailing list announcement.
