I'm working with a team that's doing some very visible work with the registry, and one of the leads showed me that if someone even slightly moves a UI element it registers as a change if the PG is versioned. That's what they expect, but they'd really like the ability to lock down components as they're working on them and then be able to lock down an entire PG once they're done with it. I added a Jira ticket for it here:
https://issues.apache.org/jira/browse/NIFI-5321 I know 1.7.0 is supposed to go up for a release vote soon, but I think this ticket is a good UX reason to hold off a little. Thanks, Mike
