Saved with the link. Notes from 2007 to 2016 are mostly the page's own words, so this is probably an excerpt.
Small copy changes like this, to action words (imperatives) instead of confirmations like ‘OK’ are a great way to make UIs more readable and quickly understood. Nice to see Apple making small changes like this.
