This version mainly updates libsoup to 3.0 from the previous 2.4. This makes it possible for the plugin to work with the latest Rhythmbox versions which are built with GTK4.
A very small change is that the Euterpe instance icon is moved to the "library" section and not "shared".
Installation
Download the release archive from the "Assets" below in the desired format. Actually, it is nothing more than the plug-in source code. Extract the contents of the archive under one of the following:
$HOME/.local/share/rhythmbox/plugins- install for a single user/usr/lib/rhythmbox/plugins- install for all users
You could rename the directory to euterpe-rhythmbox from euterpe-rhythmbox-X.Y.Z if you want to.
Open Rhythmbox, go to Prefernces -> Plugins and find "Euterpe". Then enable it.
Make sure to remove any previously installed versions.
