+Version 4.83
+------------
+
+ 1. If built with the EXPERIMENTAL_PROXY feature enabled, Exim can be
+    configured to expect an initial header from a proxy that will make the
+    actual external source IP:host be used in exim instead of the IP of the
+    proxy that is connecting to it.
+
+ 2. New verify option header_names_ascii, which will check to make sure
+    there are no non-ASCII characters in header names.  Exim itself handles
+    those non-ASCII characters, but downstream apps may not, so Exim can
+    detect and reject if those characters are present.
+
+ 3. New expansion operator ${utf8clean:string} to replace malformed UTF8
+    codepoints with valid ones.
+
+ 4. New malware type "sock".  Talks over a Unix or TCP socket, sending one
+    command line and matching a regex against the return data for trigger
+    and a second regex to extract malware_name.  The mail spoofile name can
+    be included in the command line.
+
+ 5. The smtp transport now supports options "tls_verify_hosts" and
+    "tls_try_verify_hosts".  If either is set the certificate verification
+    is split from the encryption operation. The default remains that a failed
+    verification cancels the encryption.
+
+ 6. New SERVERS override of default ldap server list.  In the ACLs, an ldap
+    lookup can now set a list of servers to use that is different from the
+    default list.
+
+ 7. New command-line option -C for exiqgrep to specify alternate exim.conf
+    file when searching the queue.
+
+ 8. EXPERIMENTAL_OCSP now supports GnuTLS also, if you have version 3.1.3
+    or later of that.
+
+ 9. Support for DNSSEC on outbound connections.
