       message has one envelope recipient. SA can use these headers,
       obviously out-of-the-box. Patch from Alex Miller.
 
+PH/08 The ${def test on a variable was returning false if the variable's
+      value was "0", contrary to what the specification has always said!
+      The result should be true unless the variable is empty.
+
+PH/09 The syntax error of a character other than { following "${if
+      def:variable_name" (after optional whitespace) was not being diagnosed.
+      An expansion such as ${if def:sender_ident:{xxx}{yyy}} in which an
+      accidental colon was present, for example, could give incorrect results.
