Looks like Magento has recently announced that it is discontinuing updating Magento 2.0.
Magento 2.0.18 is the final 2.0.x release. After March 2018, Magento 2.0.x will no longer receive security patches, quality fixes, or documentation updates. To maintain your site's performance, security, and PCI compliance, upgrade to the latest version of Magento.
Has anyone in the community heard if they plan on doing the same with 2.1 as they are with 2.0 within a similar timeline? It's not the easiest of upgrades from 2.1 to 2.2 and would be a little grateful if there any information on this at all.
