Re: Suggestions please...
I’d be very surprised if you need to find an alternative any time soon. Most likely to be impacted by future updates (or lack of them) is access to streaming services. I really can’t see pulling data from a local server being changed a great deal, certainly not anytime in the near future. If that’s all you do then I cant see any need for you ever to update, so just don’t update the speakers, don’t update the app, and you’ll probably be fine for quite a while!
