Qt 5.9.3 Released

I am pleased to inform that Qt 5.9.3 is released today. As a patch release Qt 5.9.3 does not add any new functionality, focus is in bug fixes and performance improvements.

Compared to Qt 5.9.2, the new Qt 5.9.3 contains over 100 bug fixes and in total more than 500 changes since Qt 5.9.2. For details of the most important changes, please check the Change files of Qt 5.9.3.

Qt 5.9.3 release also contains the latest security fixes, including fixes to the two vulnerabilities in Qt for Android port.

Our intention is to make frequent patch releases for Qt 5.9 LTS. Qt 5.9.4, planned for January 2018, will bring the the next set of bug fixes from Qt 5.9 branch.

If you are using the online installer, Qt 5.9.3 can be updated to using the maintenance tool. Offline packages are available for commercial users in the Qt Account portal and at the qt.io Download page for open-source users.
