Qt 6.4.2 for testing -
https://smedley.id.au/tmp/qt6-6.4.2-os2-20230311.zip - this has been tested very lightly - really just a couple of the example apps. I've tried to include all the same libraries as from Qt 6.2.4 - I even remembered the Qt5Compat lib this time
This does not (yet) include the QtWebEngine.... You can *probably* use the Qt 6.2.4 versions but I haven't tested this.
I'm hoping existing ports will work with these DLLs....
Original zip didn't include qtcharts or qttranslations, I just refreshed the zip:
