+Version 1.0.22               August 13 2013
+
+ * Fixed the combination of Mode = router and DeviceType = tap.
+
+ * The $NAME variable is now set in subnet-up/down scripts.
+
+ * Tinc now gives an error when unknown options are given on the command line.
+
+ * Tinc now correctly handles a space between a short command line option and
+   an optional argument.
