Halon's configuration is a revision managed clear-text file, where every change in the configuration is made into a new revision. It's therefore possible to compare two revisions against each other, and it's also possible to compare with your current working copy or a live staged configuration.
To start comparing, go to the Configuration -> Revisions page and choose a revision, click on the arrow to compare it with the one below. You can also compare two revisions by clicking on the left or right radio button, and they will show up in respective column.
