Based on my experience, as well as what I see on the release notes page, there were two updates in February.

I don’t recall any discussion of ‘major and minor’ releases, though. Could you point me to that, to refresh my memory, please?

I was looking at the app release page. Didn't realise there was a system release page also. 

The major / minor thing was well trailed last year. 

No app release for a month on the platform I use.

They’ve also not updated the coming soon page since December or the Trello since October or November (last time I checked). 

It would be great if Sonos could hurry up and put everything they broke back, 9+ months is a stupid lonG time to wait and it would be good to go back to not caring about updates  

Interesting. A search for quotes from Patrick Spence, who was CEO at the time, say:

We plan to continue releasing new software updates on a bi-weekly cadence. With each release, we will share detailed notes on what we’ve addressed and what we’re working on next in our Community.

There’s no mention of major / minor. I’m still searching for that, even though you state it was ‘well trailed’. Is this someone else’s interpretation of what Sonos ‘promised’?

I've googled it and the link from this screenshot doesn't work any more. 

Honestly, it was mentioned a lot more than this. I'm surprised you don't recall it, given how active you are on this forum. 

Ah, thanks. I agree, it’s unusual for me to have missed that. But I don’t see a time commitment on ‘major’ releases, and as I’ve already posted, there were at least two February releases. Not sure how to define the difference between a ‘major’ release and a ‘minor’ release, but it does seem like Sonos lived up to their commitment in that case. 

I agree there are some things that remain to be released. In my experience, working with engineering teams changing from one codebase to another, time estimates remain estimates, probably one reason Sonos is recalcitrant to give us dates. My guess is an estimate was made before a true investigation was made, but I just don’t know. I sure hope they can get back to parity ASAP, but I suspect the code team isn’t just sitting on their collective hands, and me ‘joggling’ their elbows won’t likely help. Fortunately, we have Forum Moderators to filter our feedback, something I would expect is their job. At least there are alternatives, to do everything,  from Sonos’ own desktop software, to third party apps. The mobile app is the only lagging area I’m familiar with. 

But I still don’t see how your post is factual. There were two releases in February. 

Broken promises abound.

The firmware updates seem to address only security issues and support for a new product.

The promise was for regular releases that reinstate functions and improve the overall performance.

The real issue here though is not the release cadence it is Sonos’ total disregard for the users demonstrated through the lack of regular communications. This has been an issue since 7th May 2024 they leave us in the dark and expect that to win back our trust.

Yes, that's pretty much what my next reply was going to be. 

Communication has gone out of the window after recent short lived promises to improve it.
