# Changes to Qt Modules in Qt 6

Qt 6 is a result of the conscious effort to make the framework more efficient and easy to use.

We try to maintain binary and source compatibility for all the public APIs in each release, but some changes were inevitable in an effort to make Qt a better framework. Below you can find a list of changes that may affect your application, and which can help you transitioning from Qt 5 to Qt 6.
