Essentials A60 hardware versions

Already have three Essentials A60 bulbs, all purchased from Amazon over the last few months. Just bought a new one, this time from the Apple Store, and it's running hardware firmware 2.2.5 whereas all my others are on 1.2.4. Does this imply a new bulb release, or will my others eventually update to hardware 2.2.5?

I also noticed in the Nanoleaf app on my wife's phone this new bulb supports Mijia integration whereas I can't see that option in the app on my phone although it's up to date.

Thanks for any insight!
