We recently upgraded to p4-plguin 1.9.4 and now in our multibranch jobs we see changes to the job config.xml for every branch commit. This is since p4-plugin seems to save the revision after each build:

<revision class="org.jenkinsci.plugins.p4.changes.P4ChangeRef">
  <change>3435350</change>
</revision>

In order to have useful diffs of multi branch configs we would either like another way for p4 to save this revision or for job config history to allow for filtering changes from config.xml. 

This is possiby releated to JENKINS-45821
