Hi Marek,
Qt 6 is at the moment still missing essential features/modules that do not allow a full switch of the engine and all associated features. We are constantly evaluating the progress of Qt 6, as we are also keen for the next generation of Qt. Unfortunately, since the progress of Qt 6 is not fully foreseeable, we cannot yet give an ETA.
It is not yet final if we will provide an official Qt 5 version along the Qt 6 version during a “transition-phase”.
Best,
Alex
