Hi everyone,
so I have up and running 3 Sonos One (Gen 1) speakers since forever.
Today, however, I noticed that one of them does feature a different hardware-version number than the other two — 1.21.1.8-2.1 VS 1.21.1.8-2.2
Given they‘re all Gen 1, shouldn‘t they all come with the same hardware-version?
Appreciate your insights!
Cheers!
No, all it takes is a component change to rev the hardware version. Some components get hard to obtain (see: pandemic), others reach EOL and substitutes have to be used. Sometimes a cheaper component is found for cost reduction.
Very normal in electronics.
Oh, I see!! Thanks for clarifying, controlav!
The hardware versions are transparent to us users so we can pretty much ignore them.
There is a chart around here, which I can’t find when I need it, giving a lot of the inside details.

What colour is the 1.21.1.8-2.1 speaker(s) vs the 1.21.1.8-2.2 version

1.21.1.8-2.1 speaker is white, 1.21.1.8-2.2 speakers are black. Am I right supposing that does not surprise you? 
This color theory is interesting. It matches my Play:3 devices, but my Play:5 Gen 1s are all “-1”, including the black one.
