The wrap_php_function and
            wrap_xmlrpc_method functions have been moved
            out of the base library file xmlrpc.inc into
            a file of their own: xmlrpc_wrappers.inc. You
            will have to include() / require() it in your scripts if you have
            been using those functions. For increased security, the automatic
            rebuilding of php object instances out of received xmlrpc structs
            in wrap_xmlrpc_method() has been disabled
            (but it can be optionally re-enabled). Both
            wrap_php_function() and
            wrap_xmlrpc_method() functions accept many
            more options to fine tune their behaviour, including one to return
            the php code to be saved and later used as standalone php
            script
The constructor of xmlrpcval() values has seen some internal
            changes, and it will not throw a php warning anymore when invoked
            using an unknown xmlrpc type: the error will only be written to
            php error log. Also new xmlrpcval('true', 'boolean')
            is not supported anymore
The new function
            php_xmlrpc_decode_xml() will take the xml
            representation of either an xmlrpc request, response or single
            value and return the corresponding php-xmlrpc object
            instance
A new function wrap_xmlrpc_server()has
            been added, to wrap all (or some) of the methods exposed by a
            remote xmlrpc server into a php class
A new file has been added:
            verify_compat.php, to help users diagnose the
            level of compliance of their php installation with the
            library
Restored compatibility with php 4.0.5 (for those poor souls still stuck on it)
Method xmlrpc_server->service()
            now returns a value: either the response payload or xmlrpcresp
            object instance
Method
            xmlrpc_server->add_to_map() now
            accepts xmlrpc methods with no param definitions
Documentation for single parameters of exposed methods can be added to the dispatch map (and turned into html docs in conjunction with a future release of the 'extras' package)
Full response payload is saved into xmlrpcresp object for further debugging
The debugger can now generate code that wraps a remote method into a php function (works for jsonrpc, too); it also has better support for being activated via a single GET call (e.g. for integration into other tools)
Stricter parsing of incoming xmlrpc messages: two more
            invalid cases are now detected (double data
            element inside array and
            struct/array after scalar
            inside value element)
More logging of errors in a lot of situations
Javadoc documentation of lib files (almost) complete
Many performance tweaks and code cleanups, plus the usual crop of bugs fixed (see NEWS file for complete list of bugs)
Lib internals have been modified to provide better support for grafting extra functionality on top of it. Stay tuned for future releases of the EXTRAS package (or go read Appendix B)...
