The commitment to give accurate and timely Release notes has been absent for a little while now unfortunately.
Android version 80.11.35 has been available to me for a day now but isn't mentioned anywhere that I can see. The previous release had its point version changed from what was announced and what appeared too.
Hmm… my system shows up-to-date when I perform a Searh for updates 80.11.39 for iOS. However, a manual deletion of the app and a re-install delivered the 80.11.51. Go figure?
Cross-referencing the App Store notes for 80.11.51 shows they are identical to those listed for 80.11.39 on the Sonos Release Notes page.
So to @GC3’s point, what was this update for? Either update the release notes to change .39 to .51 if they are the same thing, or detail what changed for .51.
In the scheme of things, I know it really doesn’t matter, but transparency will just keep everyone happier (especially when that is the goal right now...)!
