I am now too up to date with the latest NR version and is currently on 0.19.4, and very happy with it as everything works for me in my case. With the new 0.20 release, and scanning the forum recently, there seems to be some teething problems. This is of course normal with any new sw releases and credit and kudos to the developers and all those who upgrade and "test" new releases and contribute towards advancement of NR.
For the more risk adverse, Is there a simple list of "stable or LTS" release? and is there some consolidated documentation guide on "known issues" with each major releases or do one have to scan though the forum?
