MarsSeed [1] filed a deletion request for qt5-datavis3d-git [2]: Not useful to keep this package. Qt5 is EOL since May 2023. This PKGBUILD relies on Qt Group's public repo as source, which is typically behind the source used by the stable PKGBUILD in extra repo. Because upstream delays the public availability of Qt5 patches by one year, but allows the KDE project to cherry-pick and backport most of the patches accepted for Qt5 but not yet publicly pushed to Qt5 branch by Qt Group. The extra repo package uses KDE's updated Qt5 source. Therefore it is both better for users to use, and also newer, and has less bugs. Also this essentially makes extra/qt5* packages similar to git VCS packages. [1] https://aur.archlinux.org/account/MarsSeed/ [2] https://aur.archlinux.org/pkgbase/qt5-datavis3d-git/
