There's a good list here:
  https://chris.beams.io/posts/git-commit/

Which includes "Use the imperative mood in the subject line".

And has a good rule of thumb:

  A properly formed Git commit subject line should always be able to
  complete the following sentence:
  
  If applied, this commit will [your subject line here]


In this case Matt's subject is fine, but IMHO you should also use the
imperative mood for the body of the change log - which is basically what
you said :)
