Used the online upgrade to upgrade three computers to Leap 15.4 and apart from a few changes of repo, everything went very smoothly. Noticed a few minor changes in functionality like Kontact no longer calls KWallet directly when using LXQT but another dialogue pops up which does the job. Interestingly, Konqueror still calls KWallet directly.
Why do I need to do a distribution update to use the latest version of git? Or from LibreOffice? So that I can program in a recent version of Python? The times when Linux changed fundamentally with every distribution update are long gone. The time has come for rolling release distributions, where a one-time installation and subsequent “small” updates are sufficient.

You can also go with stable distribution and compile from source for the latest software you need 
though it’s not very convenient.
Also here on an old AMD Laptop with a Btrfs system partition –

I will admit that, I did the preparation by means of a KDE Plasma session via WiFi/WLAN and then, plugged an Ethernet cable into the nearest WLAN Repeater and, performed the Distribution Upgrade via Virtual Terminal VT1 … >:)
[HR][/HR]Only one minor gripe –
- The newest Gtk insists on underlining some of the non-English language characters but, that’s a known issue – <https://forums.opensuse.org/showthread.php/571208-Annoying-behavior-when-typing-accents>.
For me with a German language system, it’s almost never-used characters such as °, ˇ, ˛, ¸, ", ^ and so on … But for users of other languages it’s not so comfortable …
I’ve also noticed that, the battery status of the Wireless Mouse is now displayed in the KDE Plasmoid for the Laptop Battery and Screen Brightness – and, it’s also being displayed in kinfocenter …
