Google is seemingly attempting to make changelogs for apps available through the Android Market more consistent, adding a new section for developers to detail the recently added functionality when they submit updated versions of apps.  Convertor Pro developer Sterling Udell flagged up the change to us, basically a new text box on the developer site.

Details entered are then appended to the app description under a Recent Changes heading.  To be fair, many developers were doing this manually whenever they updated their software, but this will hopefully make the practice more consistent and easier to track.
