+- needed to disable ipv6 on windows for the moment, as long as i can't
+  get both ipv4 and ipv6 to work at the same time.
 - fixed getpeername was not supported on accept connections
 - fixed windows support with TCP sockets. Needed to call closesocket on windows.
 - added support for windows. Everything should work but UNIX sockets.
