Today, we released Qt 5.1.1, the first patch release for the Qt 5.1 series. It provides many improvements over Qt 5.1.0 as well as packages Qt Creator 2.8.1 to the installers. As a patch release, it does not add new features and remains binary compatible with Qt 5.1.0.

It has been 8 weeks since we released Qt 5.1.0 and we have received a lot of good feedback on the improvements it provides. Many of you have already taken the Qt Quick Controls for a spin or tried out the mobile ports for Android and iOS. Based on the feedback received from the Qt Enterprise customers as well as the whole Qt community, Qt 5.1.1 is providing improvements over Qt 5.1.0 throughout different Qt modules. We are also including Qt Creator 2.8.1 for easy installation via offline and online installers.

For a detailed list of changes in Qt 5.1.1, please have a look at the change files included in each module – or check the most important ones: qtbase, qtdeclarative, qtquickcontrols and qtmultimedia, as well as the Qt Creator 2.8.1 release announcement, and the page listing known issues for Qt 5.1.1.

As always, Qt 5.1.1 maintains both forward and backward source and binary compatibility with Qt 5.1.0. We are continuously ironing out the glitches and improving the quality with every new release. If you encounter  a previously unknown bug in Qt 5, please help us to improve the product in future releases by reporting it to bugreports.qt-project.org, or contact us via Qt Enterprise Customer Portal.

Qt 5.1.1 is now tagged in the Qt Project repository. The source packages and installers for Qt 5.1.1 are available through the online installer, qt-project.org/downloads for open-source users, and in the Qt Enterprise Customer Portal for existing customers. If you would like to try the Qt Enterprise version of Qt 5.1.1, please get the 30-day free trial.
