+4.4.18 Final
+
+1)  Previously, if an IPv6 host address (no "/<vlsm>") was used in a
+    context where a network address is allowed, the compiler failed to
+    supply the default <vlsm> of 128. This could lead to startup errors
+    and/or Perl errors such as:
+
+    	   Use of uninitialized value $mask in concatenation (.) or
+    	   string at /usr/share/shorewall/Shorewall/Tc.pm line 979,
+    	   <$currentfile> line 11.

 4.4.18 RC 1
 
 1)  None.
