We are doing some improvements around the "Editing" setting. In several interviews we were assured that working on a news or page with several authors is best done when all authors have the same rights.
In this first improvement, we allow other people than the main author (the one shown as author on the page) to change the editing settings. This gives more flexibility in defining the right group of people that should work on any given page.
Expect a few more release notes in this area pretty soon!
