General:
========
* Better support for "one-way" operations, both on the client side and on the server side (now using "HTTP 204 No Content").

* Fix writing out prefixes on unqualified attributes (e.g. with the MSExchange WSDL) (SOAP-111)

Client-side:
============
* Remove encodingStyle attribute, as Microsoft EWS servers reject it. Please contact
KDSoap support if this causes a regression with any other SOAP server.

* Add support for ignoring a specific list of SSL errors: KDSoapClientInterface::ignoreSslErrors(QList<QSslError>)
and KDSoapSslHandler::ignoreSslErrors(QList<QSslError>) (SOAP-92)

* Fix crash when using sslHandler() and making a synchronous call (SOAP-79/issue29)

* Fix race conditions in KDSoapNamespaceManager on Windows, because MSVC doesn't implement threadsafe statics (issue41).

Server-side:
============
* Fix crash when sending delayed reply to disconnected client (SOAP-34/SOAP-67)

* Add doneProcessingRequestWithPath() for copying fault info and response headers from secondary object to primary one.
  The method is to be called after processRequestWithPath delegates the request to another object interface.

* Fix support for multiple message parts in RPC mode.

Code generator changes, applying to both client and server side:
================================================================
* Only set xsi:nil="true" on elements that are marked as nillable in the WSDL file.
* Omit non-nillable empty elements of a complex type.
* Support for minOccurs=0 for elements and use=optional for attributes:
   omit such elements/attributes when they haven't been set by the C++ code explicitly. (SOAP-93/SOAP-80)
   optionally wrap them in a boost::optional or use raw pointers so apps can find out the element is missing (issue43).
* Support for attributes marked as "prohibited", ensuring they are not settable nor sent in the request. (SOAP-102)
* Generate <service> element automatically if there's none in the WSDL file. (SOAP-60/issue9)
* Implement support for inheritance between complex types, using QSharedPointer as internal storage. (issue26/SOAP-87/SOAP-62)
* Implement support for substitutionGroup, in order to send the correct element name (SOAP-87 followup, SOAP-97).
* Fix crash when parsing elements without a type.
