I just received email saying that there's an update for 2.1.x > 2.1.10. There are also updates for 2.0.x and 2.2.x.
Is there end-of-life date for Magento 2.1.x? Do they plan to develop 2.0.x, 2.1.x and 2.2.x in parallel?
I'm wondering whether to upgrade from 2.1.9 to 2.2.1 or just keep updating to next versions of 2.1.x - when available.
