+2003-07-21, version 0.6.5
+- soap_transport_http: SOAPAction header is quoted again, fixes problem w/ Weblogic Server
+- applied Jason Levitt patch for proper array serialization, fixes problem w/ Amazon shopping cart services
+- fixed null value serialization
+- applied patch from "BZC ToOn'S" - fixes wsdl serialization when no parameters
+- applied John's patch, implementing compression for the server
+
+2003-07-22, version 0.6.5
+- soap_server: fixed bug causing charset encoding not to be passed to the parser
+- soap_fault: added default encoding to the fault serialization
+- soap_parser: changed the parser to pre-load the parent's result array when processing scalar values. This increases parsing speed.
+
+2003-07-23, version 0.6.5
+- soap_base: fix code that overwrites user-supplied attributes in serialize_val
+- soap_base: use arrays-of-arrays rather than attempting multi-dimensional in serialize_val

+- soapclient: get xml character encoding from HTTP Content-Type header if provided, e.g. text/xml;charset="UTF-8"
+- soapclient: use headers in call if provided (previously ignored this parameter)
+- soap_server: in parse_request, if neither getallheaders nor $_SERVER are available, use $HTTP_SERVER_VARS to get SOAPAction and xml encoding

+
+2003-07-30, version 0.6.5
+- nusoap_base: change documentation of soap_defencoding to specify it is the encoding for outgoing messages

+                                 the following...
+> Changes for the multiple/nested imports from the wsdl file. This builds an
