Git commit summary in Jenkins job page

We have recently moved our Jenkins service to a new (Windows) machine by copying the JENKINS_HOME. All stuff came over and it seems to work fine.

However, now that we’ve used it a few weeks and the old server is gone, we noticed that we used to have some sort of summary of the commits within that build. I’m not really sure how it looked, but I suppose it showed the committer and the description of the commit at the top of the build page. Today it only shows the revision and the repository but nothing more.

I’ve tried to find what it was that did that. I suppose it must have been some plugin or something, but I am not sure. I took a look at a plugin that is called Git Changelog but there is a lot of configuration and I am pretty sure we didn’t have those configurations in the project configuration window before.

The most obvious cause for it to go missing is the server change but we’ve updated plugins and Jenkins itself also several times since the move, so I’m not sure. It is not even certain it wasn’t already gone when we moved to the new server.

Any idea what generated that commit summary and how to get it back?
