We used 1.6 for a large project in 2014 or so, the 2.x release removed key features for us and we were never able to upgrade. The direction they went after that just never really worked for us so we only have that legacy project still running.

CouchDB dev here. 2.x only added new features, not sure what you’re referring to that was removed. The only on incompatibility was the changes feed ids moving from numbers to strings, which is hardly a huge migration :)
