     Unless you really know what you are doing, leave it alone.
 
+ 4. If not built with DISABLE_DNSSEC, Exim now has the main option
+    dns_use_dnssec; if set to 1 then Exim will initialise the resolver library
+    to send the DO flag to your recursive resolver.  If you have a recursive
+    resolver, which can set the Authenticated Data (AD) flag in results, Exim
+    can now detect this.
+
+    Current status: work-in-progress; $sender_host_dnssec variable added.
+
+ 5. DSCP support for outbound connections: on a transport using the smtp driver,
+    set "dscp = ef", for instance, to cause the connections to have the relevant
+    DSCP (IPv4 TOS or IPv6 TCLASS) value in the header.
+
+    Similarly for inbound connections, there is a new control modifier, dscp,
+    so "warn control = dscp/ef" in the connect ACL, or after authentication.
+
+    Supported values depend upon system libraries.  "exim -bI:dscp" to list the
+    ones Exim knows of.  You can also set a raw number 0..0x3F.
