Good morning MusErs, long time no hear, sorry to say...
I just wanted to mention that the AppImages are since yesterday based on Ubuntu 20.04 image instead of 18.04.
Though AppImages by themselves are distro independent, they are infact built on a base image from a standard distro.
The reason for this change is out of necessity. The build system on github completely stops supporting 18.04 as base image very soon.
So, if anyone is interested in the AppImage versions we are interested in reports on compatibility for this image.
