I'm always pleased to receive updates to my Sonos software.
To be honest though, I've not really seen any major changes since I've been using the kit... 8years. It's not Spotify integration that interests me, it's seeing other products coming to market that offer voice control functionality. Whilst I absolutely know the quality of the Sonos sound is excellent, it's becoming increasingly the case that I'm looking to the feature rich alternatives, that perhaps give an overall better package. For me, voice integration is a natural progression... even if that isn't directly via the Sonos units, but via my smart phone. I think Sonos could end up being left behind in the wider environment - sound quality isn't the only consideration of most users.
