An update for the Windows Phone 7 Developer tools was released in the last couple of weeks. The update is available here and provides:

• A new Bing Maps Control that improves map performance during user gestures
• The Capability Detection Tool, which scans your application and reports on detected phone capabilities that will be applied during ingestion to marketplace.
• The WP Connect Tool, with which you can create a connection between the Windows Phone and your PC without requiring Zune to be running, so you can debug media APIs.

More information on the Capability Detection Tool is available here, and details on the WP Connect Tool are here. The update requires that you have the Windows Phone Developer Tools installed and that language/locale of the update and developer tools match.
