Recent changes to Android Market that require developers' attention

First, Google have added support for a recent changes feature, which allows developers to add notes about changes specific to the newest version of application. Developers are able to submit these from the Developer Console, similar to descriptions. In the Market app, these notes will appear under the app description as "Recent changes."

Second, there is now a ‘draft upload’ capability for application updates. This feature enables developers to edit app listing and upload a new version without affecting the version live in Market. The app listing edits will not change the live listing until developer select “Publish.”

Finally, Google are adding support for larger promotional graphics to showcase application. In addition to the currently required app screenshot, developers will be required to upload one “feature” graphic. Supported promotional assets will now include:
- A “feature” graphic, landscape aspect ratio, 1024 x 500 (required).
- A high-res icon, 512 x 512 (required).. The Android icon design guidelines located at http://developer.android.com/guide/practices/ui_guidelines/icon_design.html apply.
- 2 screen shots, 320w x 480h, 480w x 854h, or 480w x 800h, increasing to 8 screen shots in the future (1 required).
- A link for a promotional video hosted on YouTube (optional).
