Jenkins Changelog for Git tags

Question

I am trying to set up Jenkins to generate its change-log based on changes in the Git repository since a given tag.

Does anyone know of a way to do this?

I've tried using the "Calculate change-log against a specific branch" advanced behavior with a few different options like:

• Name of repository: Origin
• Name of branch: refs/tags/mytag

But am getting errors like:

Using 'Changelog to branch' strategy.
fatal: bad revision '^origin/refs/tags/mytag'
ERROR: Unable to retrieve changeset
