Don't really get the bulletted points here.  What do they really mean?
 * "the aim of the change" : Not clear, perhaps just "the problem addressed -- often linked to a GitHub issue" ? 
 * "how the change has been delivered"  : it's always visible what code has changed, so what else do you think may be typically needed here?

Maybe for the whole thing, just "a brief summary of what has changed and why."
