When using a previous version of the Delivery Pipeline Plugin in our project (unfortunately I don't know which one, but probably a version prior to 0.6.8), a list of committers were included in the headline of each pipeline triggered by an SCM change in Git or Subversion.
In later versions (including 0.7.4) only "triggered by SCM change" is shown in the headline, which is much less informative. Please see attached screenshot (pipeline_without_patch.png).
I created a quick local quick fix for this problem, which makes the pipeline heading look like the second screenshot (pipeline_with_patch.png). That quick fix has now been submitted as a pull request: https://github.com/Diabol/delivery-pipeline-plugin/pull/62
