Maybe only bug fixes.

Generally speaking, Spotify doesn’t tend to do major noticeable changes to the client on desktop... and hasn’t done so for a couple of years now. I’m not complaining; it’s mostly intuitive, but yeah, they generally go the “if it ain’t broke” route on desktop and not on mobile.

@handymanshandle I still want a light theme... 

Most Spotify desktop updates are updating chromium under the hood.

Because the way Spotify works is that the desktop app is a thin client that at its core is a chromium browser window running the UI (on the Microsoft Store version this would probably be Edge based instead but I don’t know for sure) which is entirely web based.

Anything involving decision making, algorithmic stuff, is done on the server side and communicated to the client minus the shuffle play algorithm which is done locally in the client.

The client is also responsible for: storing app preferences, displaying ADs as required by the server if the user isn’t a paying customer, caching songs to reduce how often they need to be streamed from the server, downloading songs for offline playback if a paying customer wants to download songs, and updating itself to make sure the customer has the latest version of the app.
