Windows Phone App Hub Marketplace updated with tons of new features: Mango application submission starting in August

Microsoft has just officially announced the new Windows Phone 7 developer App Hub updates and features that the company is rolling out today:

Geographic expansion: publish to 19 new consumer markets, submit from 7 new developer markets and coming soon, expansion of markets for in-app advertising!
New private distribution options: developers can now privately distribute their apps using beta and targeted distribution options.
Enhanced application management: we’ve made a lot of additional improvements to how you manage and publish your application in the App Hub itself, in response to your feedback: Better application management, Enhanced developer dashboard, More detailed reporting, New ‘Crash Count’ report, Streamlined application submission process, New App Categorie.

The PubCenter in app advertising will finally be made available to developers in 18 new counties by the end of 2011: Australia, Belgium, Canada, Denmark, Finland, France, Germany, Hong Kong, India, Italy, Japan, Mexico, Netherlands, Norway, Spain, Sweden, Switzerland and the United Kingdom.

Microsoft is also announcing that Mango application submission will be open on August 22 and that the Release Candidate of the developer Tools will be made available in late August (most probably on the 22th too):

We’re just about a month away from enabling developers to begin submitting Mango apps to App Hub. Developers will need to use the Windows Phone Release Candidate (RC) tools that we expect to make available in late August to finalize their Mango apps and submit to App Hub.
