Hello Philip, Kiasoc5, Efraim, thanks a lot for your input!
Indeed I got my information that Qt 5 was phased out from Wikipedia, which mentioned May 2021 as the end of support. I did not expect there to be more versions! But then discovered the 5.15.8 version, probably related to the commercial support available until May this year? Anyway, I updated in my own branch wip-andreas-core-updates (since I wanted to avoid rebuilding core-updates with its recent world-rebuilding changes); just qtwebengine takes 6 hours on my laptop... (And it required the update, since it would not build at version 5.15.5.) Now I am trying to build all the Qt packages before applying the patch to core-updates; it looks good so far. Andreas
