While there are a _number_ of 'in-production' right now, the one I can personally speak to is at https://connamara.cloudant.com/cme/_design/app/index.html [disclaimer: this is my employer].
For what it's worth, I must say that I was very impressed today with how much 'better behaved' this release was in comparison to bother previous "major" releases (0.11 for example) _and_ recent trunk snapshots. In particular, they seem to have ironed out the nagging dependency issues couch had displayed on debian-based installations and are now reliably passing all of the unit / end-to-end tests.
Great work.
