One word on the nrkno-fork: It is an intermediate step for the timeline of 2018 only until 2.2 can be finalised. We will contribute by merging all relevant tings in nrkno upstream to 2.2 and focus all development efforts on 2.2. It’s just a matter of timing and priorities that have spawned out the need for this 2.1 variant right now.
But as @mint says, it is a pretty good version (currently the best?) in my opinion.
