We are happy to announce the release of Qt Creator 4.2.1. This is a pure bugfix release, and takes care of various important bugs.

Several properties of run configurations were only initialized when entering the Projects

mode, leading to various issues when running QMake projects, and projects that run custom executables, which have now been fixed.

In 4.2 we fixed iOS Simulator support for Xcode 8. Unfortunately there still were

problems, especially when running on iOS 10 simulator devices.

We adapted the way we start applications on the simulator, and this should now reliably

work again.

There have been a range of smaller bug fixes as well, please have a look at our change log

for more details.
