 New Features in Exim

     so that safety mechanism would have to be overriden for this option to
     be able to take effect.
 
+ 3. ClamAV 0.95 is now required for ClamAV support in Exim, unless
+    Local/Makefile sets: WITH_OLD_CLAMAV_STREAM=yes
+    Note that this switches Exim to use a new API ("INSTREAM") and a future
+    release of ClamAV will remove support for the old API ("STREAM").
+
+    The av_scanner option, when set to "clamd", now takes an optional third
+    part, "local", which causes Exim to pass a filename to ClamAV instead of
+    the file content.  This is the same behaviour as when clamd is pointed at
+    a Unix-domain socket.  For example:
+
+      av_scanner = clamd:192.0.2.3 1234:local
+
+ 4. There is now a -bmalware option, restricted to admin users.  This option
+    takes one parameter, a filename, and scans that file with Exim's
+    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
+
