D3SOX [1] filed a deletion request for heidisql-qt5 [2]: Qt6 bindings for LCL are stable. https://wiki.freepascal.org/Roadmap does not make a distinction between the Qt versions. Every bug I had with the Qt6 version was also reproducible using Qt5. So I see no point in having the Qt5 version anymore. Especially because it's officially EOL and receives only very little maintenance by KDE at this point. [1] https://aur.archlinux.org/account/D3SOX/ [2] https://aur.archlinux.org/pkgbase/heidisql-qt5/
