+* improvements to the support of the XMLRPC extension emulation (now provided by the phpxmlrpc/polyfill-xmlrpc package)
+
+* minor improvements to the Charset helper: it now loads character set conversion tables on demand, leading to
+ slightly lower memory usage and faster execution time when using UTF8 everywhere.
+ NB: take care if you have subclassed it!
+
+* new method: `Server::isSyscall` - mostly of use to Server subclasses and friend classes such as introspectors
