I didn't have the time to test the pre-release snapshots, but I am now 
updating SIP from 6.6.2 to 6.7.1 for openSUSE Tumbleweed. Acceptance 
into the distribtution is not possible right now, because it fails to 
build wxPython:

wxEvent&)’:

and so on.

The full failing build log can be found here: 
https://paste.opensuse.org/63871699

The diff for the failing generated cpp code is here: 
https://paste.opensuse.org/71620253

The etg-generated .sip code is here: 
https://cloud.bnavigator.de/index.php/s/EL3ZmGqHgwWdiJ5, differing 
slightly from those shipped with the wxPython 4.2.0 sdist on PyPI.

Regards, Ben

P.S.: QGIS successfully builds with the new SIP.
