Porting guide

When creating Qt 6, we retain as much compatibility with Qt 5 as possible, but some changes were inevitable to make Qt a better framework. To make it easier to port to Qt 6, we have created a Porting guide to summarize those changes and provide guidance to handle them. In the guide, you can find links to articles about changes that may affect your application and help you transitioning from Qt 5 to Qt 6.
