* Add <tt>ActionWebService::API::Base.allow_active_record_expects</tt> option, with a default of false. Setting this to true will allow specifying ActiveRecord::Base model classes in <tt>:expects</tt>. API writers should take care to validate the received ActiveRecord model objects when turning it on, and/or have an authentication mechanism in place to reduce the security risk.
* Improve error message reporting. Bugs in either AWS or the web service itself will send back a protocol-specific error report message if possible, otherwise, provide as much detail as possible.
* Removed type checking of received parameters, and perform casting for XML-RPC if possible, but fallback to the received parameters if casting fails, closes #677
* Refactored SOAP and XML-RPC marshaling and encoding into a small library devoted exclusively to protocol specifics, also cleaned up the SOAP marshaling approach, so that array and custom type marshaling should be a bit faster.
* Add namespaced XML-RPC method name support, closes #678
* Replace '::' with '..' in fully qualified type names for marshaling and WSDL. This improves interoperability with .NET, and closes #676.
