Bryan Bende commented on NIFIREG-77:
------------------------------------

[~JPercivall] [~rmoran] Is this JIRA primarily talking about the NiFi UI, the 
registry UI, or both?

I'd like to be able to select two versions in the registry UI and compare them, 
or possibly compare a version with previous since I would usually be interested 
in changes between two versions.

I also agree that we should have a way for the NiFi side to show differences 
between the current version and whatever is available for upgrade, however that 
should probably be a JIRA on the NiFi side which would potentially call/use 
something developed in this JIRA.

> As a user, I would like to see the changes that are included in a particular 
> version. More specifically, if I'm on an old version and I upgrade to a 
> version written by someone else, I have no way to know what changes occurred 
> during that version upgrade.
> A simple solution would be to utilize the same logic which displays the 
> current differences between local and stored in the registry and use that to 
> show the differences between the current version N and version N-1. The user 
> could then change between versions to see the changes that happened as part 
> of that version.
> An even better solution (from a DFM perspective) would be to be able to see 
> the changes within any version (not just the most recent). That way a DFM 
> wouldn't have to stop the flow for an extended period of time to view the 
> changes/differences in different versions but I think that'd be more work.
