Microsoft overhauled their developer website AppHub and included a few new Windows Phone 7 OS "Mango" specific features including:
- Updated layout
- New crash reports
- Export of download/purchase details
- Private beta Marketplace
The private beta marketplace allows developers to run beta programs via the marketplace, so that rather than sideloading the XAP file a URL can be provided to other users and the developer can push updates to the beta software via the marketplace rather than sending out new XAP files to be sideloaded every time.
In short, it means devs can expand their testing pool to beyond those with developer unlocked devices, as well as "manage" the software including pushing updates. It should be a powerful tool the community and developers to get better apps to the Marketplace for final release.
Another new feature for devs is "edit application details":
"The...feature makes it easy for application developers to make changes to the application's listing in the marketplace and description without having to submit a new version. The developer can the edit applications category, artwork and category."
Here's a picture showing the download/crash counters in action:
