The long deprecated signon_auth_session_process()
has been removed and
the signon_auth_session_process_async()
method has been renamed to
signon_auth_session_process()
as asynchronous methods are the default
way to use this API.
signon_auth_session_query_available_mechanisms()
has been removed and
can be replaced by signon_auth_service_get_mechanisms()
with a manual
filtering if needed.
