 New Features in Exim

     malware-scanning framework.  This is intended purely as a debugging aid
     to ensure that Exim's scanning is working, not to replace other tools.
 
+ 5. There is a new expansion operator, "reverse_ip", which will reverse IP
+    addresses; IPv4 into dotted quad, IPv6 into dotted nibble.  Examples:
+
+      ${reverse_ip:192.0.2.4}
+       -> 4.2.0.192
+      ${reverse_ip:2001:0db8:c42:9:1:abcd:192.0.2.3}
+       -> 3.0.2.0.0.0.0.c.d.c.b.a.1.0.0.0.9.0.0.0.2.4.c.0.8.b.d.0.1.0.0.2
+
+ 6. There is a new ACL control called "debug", to enable debug logging.
+    This allows selective logging of certain incoming transactions within
+    production environments, with some care.  It takes two options, "tag"
+    and "opts"; "tag" is included in the filename of the log and "opts"
+    is used as per the -d<options> command-line option.  Examples, which
+    don't all make sense in all contexts:
+
+      control = debug
+      control = debug/tag=.$sender_host_address
+      control = debug/opts=+expand+acl
+      control = debug/tag=.$message_exim_id/opts=+expand
