On the Manage Plugins page, you see columns for version installed, available.

User has to go to plugin page, find changes in latest, edit the query, to compare what went in between installed and current.

This is indirect/annoying especially if more than one version exists between the two

Could you add a column with a direct URL,

e.g.

If manage plugin has row like:

[Warnings Plugin | 4.38 | 4.35]

can you add a column (header=delta

)

https://github.com/jenkinsci/warnings-plugin/compare/warnings-4.35...warnings-4.38

not sure if plugin names and git paths are pattern suitable, or look up if not, OW this is an opportunity to regularize that too...
