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.
Wow! The exact same happen with me. Thanks for your imformation. It helps for my job.
