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.

Congratulations. This new pace of bugfix releases is very nice.

GDeR says:

I think Qt Creator 4.4.1 needs to be rebuilt against the new 5.9.3 library.
I’m getting the following error when launching it:
Cannot mix incompatible Qt library (version 0x50903) with this library (version 0x50902)
Aborted (core dumped)

Nice work, merci!

If Qt 5.9.4 is released in January, it will probably make it to Ubuntu 18.04 LTS, so make that rock solid 🙂

Good work!

I Love Qt <3 Thank You 😀 😀

Peter says:

Thanks! Maybe someone could have a look at this bug which already has a patch but has not been released in 5.9.3.

@Peter: The fix is not yet merged. It will be in Qt 5.9.4 if completed and merged in time.

Bernhard says:

Thank you! We are also very happy with the improved release schedule. Many important bugs have been fixed, especially for applications that have to rely on QuickWidgets.

Unfortunately this release breaks getting the sender address of a UDP packet on Windows:

It is possible to work around with a simple code change, but still quite unexpected.

HM says:

Are there plans to fix the QTBUG-63476 iOS bug?

NoName says:

Please add a 32-bit VS2017 Version too

Nikita says:

Multitouch support in Quick Controls 2 is still buggy. RangeSlider is impossible to use with two fingers.
Is there a way to disable multitouch support?
