Release 2.2.5 Tue October 31 2017
        Bug fixes:
              #8  If the parser runs out of memory, make sure its internal
                    state reflects the memory it actually has, not the memory
                    it wanted to have.
             #11  The default handler wasn't being called when it should for
                    a SYSTEM or PUBLIC doctype if an entity declaration handler
                    was registered.
       #137 #138  Fix a case of mistakenly reported parsing success where
                    XML_StopParser was called from an element handler
            #162  Function XML_ErrorString was returning NULL rather than
                    a message for code XML_ERROR_INVALID_ARGUMENT
                    introduced with release 2.2.1
