How do you define "stable"?

The best criteria I have to offer at this point is a pass of all tests of all modules in a combination. That is a qt5 build and that is why it is - by the metric of test failures - more stable at the untested combination of branch tips of the modules.

That is the criteria for developers of Qt.

For the users of Qt only tags go further, because they come after release test automation- an additional step of QA.
