 1)  The BGP and OSFP macros released in Beta 3 contained rules to allow
     administrative access to the related routing daemons. Those rules
     have been deleted.
 
+2)  Previously, if Address Type Match was not available and an
+    interface on the firewall was (mis-)configured as shown below, then
+    REJECT policies in Shorewall-perl would drop packets addressed to
+    the interface rather than reject them.

+
+    Note that a /32 should never be configured with a broadcast
+    address.
+
+3)  Due to a syntax ambiguity arising from the new dynamic zone
+    implementation, 'shorewall show dynamic' produced no output. It now
+    shows the contents of the dynamic blacklist as in earlier 
+    Shorewall releases.
+
+4)  The 'findgw' script produced an error if VERBOSITY > 0.
