Windows Azure App Fabric Team has released updated version of Windows Azure App Fabric with following update:

Access Control

The following updates have been made to all ACS 2.0 namespaces.

Rules now support up to two input claims
The ACS 2.0 rules engine now supports a new type of rule that allows up to two input claims to be configured, instead of only one input claim. Rules with two input claims can be used to reduce the overall number of rules required to perform complex user authorization functions. For more information on rules with two input claims, seehttp://msdn.microsoft.com/en-us/library/gg185923.aspx.
Encoding is now UTF-8 for all OAuth 2.0 responses

In the initial release of ACS 2.0, the character encoding set for all HTTP responses from the OAuth 2.0 endpoint was US-ASCII. In the July 2011 release, the character encoding of HTTP responses is now set to UTF-8 to support extended character sets.

Quotas Removed

The previous quotas on configuration data have been removed in this release. This includes removal of all limitations on the number of identity providers, relying party applications, rule groups, rules, service identities, claim types, delegation records, issuers, keys, and addresses that can be created in a given ACS namespace.
