AppFabric Azure Access Control New Features
AppFabric Azure Access control service was released with very small set of features which were mainly targeted to REST web services.
Now the ACS comes in a new version with a much larger set of features and capabilities.

Out-of-the-box support for popular web identity providers including:
Windows Live ID, Google, Yahoo, and Facebook
Out-of-the-box support for Active Directory Federation Server v2.0
Support for OAuth WRAP, WS-Trust, and WS-Federation protocols
Support for the SAML 1.1, SAML 2.0, and Simple Web Token (SWT) token formats
Integrated and customizable Home Realm Discovery that allows users to choose
their identity provider
An OData-based Management Service that provides programmatic access to
ACS configuration
A Web Portal that allows administrative access to ACS configuration
The new version is not in production yet but it is possible to play with it in the Azure AppFabricLabs
