I currently am using Sonos 79.01-53290. Like many people, either this or the disastrous Sonos App for iOS and Android or both, I suffered the infamous Error 913 file sharing problem. Fortunately for me, but not for everyone, there was a solution posted on Sonos Community that was a workaround. It took a good month to fix that. And the solution DID NOT come from Sonos help desk but from Sonos Community.
I have since stuck to no more updates hoping error free/stable software would eventually come.
While I have a choice NOT to update to the latest software, my S2 controller (79.01-53290) now will not allow me to update my NAS music library unless I download the latest version of S2 --- Sonos euphemously says “you will have limited functionality unless you update”. Now thta’s limited functionality alright.
I went to the Sonos download page and downloaded without executing the latest version and I can see it says Version 80.1-55014.
Questions: Does this work? Any known bugs? Is this S2 Version16.2? 16.3?
The “sincere apology” the Sonos CEO sent pointed to a link that detailed version updates to Sonos App for iOS and Android. Nothing on the S2.
Thanks
