Update to QT 5.12.1
Changelog available here
Installed and rebooted
What about qownnotes? musescore? etc.
What happened here? Are they not using qt5-xmlpatterns anymore? If not, builddep sohuld be removed. But seeing as the purpose of this library is to handle "string, xml, and network handling" - the lack of XML bit is concerning.
Looks like the XMLListModel was moved to xmlpatterns in 5.12.0 per http://code.qt.io/cgit/qt/qtdeclarative.git/commit/?h=v5.12.1&id=0477a057fd02050fd330760bf046f5e0e91a9331 so going to accept this.
