It is nice to see that the binding is updated!
I am also very happy that the album image is now embedded inside the binding.
Unfortunately the binding has a bug at my OpenHAB.
The data is only updated when a track is started/paused or skipped from within openhab.
When Spotify is controlled form elsewhere (e.g. my pc) the data (title, artist and stuff) isn’t updated.
Also the player bridge keeps switching between online and offline as I can see in the log. I hope you can help me with it, if you need more information about the bug I would like to hear it!
Also I really miss the custom Spotify request which was available in version 2.2.0, because I use this to retrieve a list of my playlist into openhab. Is there a reason why you deleted it?
