- Log any email notification (successful or not) - Class selection always made through a Combo box - Automatic creation of indexes for external keys - New trigger: on object creation - Application log: added a status string - Added documentation to the WSDL (+ anyType replaced by string) - SOAP: improved handling of enumeration attributes - SOAP: returned logs to mention the name of the parameter as advertised in the WSDL file (different than the name of the attribute in Itop) - Finalized SOAP tests - Added a SOAP client example SVN:trunk[246]
