Had not heard of these, interesting ... "A typical use of notes is to supplement a commit message without changing the commit itself. Notes can be shown by git log along with the original commit message. To distinguish these notes from the message stored in the commit object, the notes are indented like the message, after an unindented line saying "Notes (<refname>):" (or "Notes:" for refs/notes/commits)."
