Add a "What's New?" Section to Marketplace Items

Marketplace items update, but you have no idea what has changed or if you want to re-integrate the new version into your project.

Proposed Solution:
Add a “What’s New?” section for each revision like Google Play or iTunes so marketplace developers can say what has changed.

Please forgive me if this is already done somewhere, but I’ve not been able to find any example of it.

Aaand I just saw that there is a “Marketplace” tag. Mods please change if appropriate. Sorry.
