Thanks for the pull request. Have you checked if https://github.com/nullobsi/cantata/blob/main/support/QtAwesomeEnumGenerated.h needs to be updated? I believe upstream QtAwesome gamecreature/QtAwesome@e823065 has already made this upgrade and they regenerated the enum files, so that would need to be updated too.

Thanks for the hint, additionally there's a QtAwesomeStringGenerated.h I've now updated as well. Upstream changed the formatting a bit, e.g. indent with spaces instead of tabs now but I've kept it like it was to have an easy readable diff. (I wonder if it would rather make sense to just update the bundled QtAwesome alltogether than picking single changes, but for now this works.)

There are some slight changes made in the bundled copy, but it hasn't deviated much. It seems the upstream changes are mostly to add support for new paid FontAwesome symbols which we don't use.
