QT related problems after upgrade 7.6 --> 7.7

First of all: I am very happy about the new release and thank all the
developers and maintainers. Thank you for the work!

But this is the first time I have significant problems after the upgrade.

The base upgrade was running as extected without any hickups.

But 'pkg_add -u' results in a lot of errors concerning the QT(6) framework.

Mostly dependency errors like this:

'Dependency of <program or lib> on qt6-<someprog> ->=6.6.3, <6.7.0
doesn't match'

...and - as often - some gstreamer-plugins-xxxxx - trouble, but this is
minor...

All applications running the qt framework misbehave or did't run at all
(core dump).

Am I the only one with QT related problems?

best regards
