AppImage -- non-bug report
I had reason to install MS 3.4.2 on Ubuntu. I'd never seen AppImage before, but this is the greatest thing since sliced bread. I spent some years maintaining an MSI installer (Microsoft database-based), the hairiest thing since Bigfoot, which is torture both to prepare (and debug) and even use. Once I learned about AppImage (and I both ran it raw and "install"ed it), all was set. Way to go!
