There is at least one reason for high DPI users not to upgrade Leap past 42.1: GTK3 apps not honoring system-wide DPI settings nor KDE mouse cursor https://bugzilla.opensuse.org/show_bug.cgi?id=1022830 [GTK+ 3.18] UI text sizes no longer inherited from Linux system https://bugzilla.mozilla.org/show_bug.cgi?id=1269274 The same reason applies to Stretch, all currently supported Fedoras, Ubuntu 16.04 & up, Mint 18+, anything that includes unpatched gtk >3.16. Last night I did a final update on one 42.1 system and had to use the TDE 42.2 repos to do it. I understand killing 13.1 & 13.2, but not 42.1 or 42.2.
