+Version 4.70 / 4.71
+-------------------
+
+ 1. Native DKIM support without an external library.
+
+ 2. Experimental DCC support via dccifd (contributed by Wolfgang Breyha).
+
+ 3. There is now a bool{} expansion condition which maps certain strings to
+    true/false condition values (most likely of use in conjuction with the
+    and{} expansion operator).
+
+ 4. The $spam_score, $spam_bar and $spam_report variables are now available
+    at delivery time.
+
+ 5. exim -bP now supports "macros", "macro_list" or "macro MACRO_NAME" as
+    options, provided that Exim is invoked by an admin_user.
+
+ 6. There is a new option gnutls_compat_mode, when linked against GnuTLS,
+    which increases compatibility with older clients at the cost of decreased
+    security.  Don't set this unless you need to support such clients.
+
+ 7. There is a new expansion operator, ${randint:...} which will produce a
+    "random" number less than the supplied integer.  This randomness is
+    not guaranteed to be cryptographically strong, but depending upon how
+    Exim was built may be better than the most naive schemes.
+
+ 8. Exim now explicitly ensures that SHA256 is available when linked against
+    OpenSSL.
+
+ 9. The transport_filter_timeout option now applies to SMTP transports too.

     the load for each incoming message in an SMTP session. Otherwise, once one
     message is queued, the remainder are also.
 

+ 9. There is a new ACL, specified by acl_smtp_notquit, which is run in most
+    cases when an SMTP session ends without sending QUIT. However, when Exim
+    itself is is bad trouble, such as being unable to write to its log files,
+    this ACL is not run, because it might try to do things (such as write to
+    log files) that make the situation even worse.
+
+    Like the QUIT ACL, this new ACL is provided to make it possible to gather
+    statistics. Whatever it returns (accept or deny) is immaterial. The "delay"
+    modifier is forbidden in this ACL.
+
+    When the NOTQUIT ACL is running, the variable $smtp_notquit_reason is set
+    to a string that indicates the reason for the termination of the SMTP
+    connection. The possible values are:
+
+      acl-drop                 Another ACL issued a "drop" command
+      bad-commands             Too many unknown or non-mail commands
+      command-timeout          Timeout while reading SMTP commands
+      connection-lost          The SMTP connection has been lost
+      data-timeout             Timeout while reading message data
+      local-scan-error         The local_scan() function crashed
+      local-scan-timeout       The local_scan() function timed out
+      signal-exit              SIGTERM or SIGINT
+      synchronization-error    SMTP synchronization error
+      tls-failed               TLS failed to start
+
+    In most cases when an SMTP connection is closed without having received
+    QUIT, Exim sends an SMTP response message before actually closing the
+    connection. With the exception of acl-drop, the default message can be
+    overridden by the "message" modifier in the NOTQUIT ACL. In the case of a
+    "drop" verb in another ACL, it is the message from the other ACL that is
+    used.
+
+10. For MySQL and PostgreSQL lookups, it is now possible to specify a list of
+    servers with individual queries. This is done by starting the query with
+    "servers=x:y:z;", where each item in the list may take one of two forms:
+
+    (1) If it is just a host name, the appropriate global option (mysql_servers
+        or pgsql_servers) is searched for a host of the same name, and the
+        remaining parameters (database, user, password) are taken from there.
+
+    (2) If it contains any slashes, it is taken as a complete parameter set.
+
+    The list of servers is used in exactly the same was as the global list.
+    Once a connection to a server has happened and a query has been
+    successfully executed, processing of the lookup ceases.
+
+    This feature is intended for use in master/slave situations where updates
+    are occurring, and one wants to update a master rather than a slave. If the
+    masters are in the list for reading, you might have:
+
+      mysql_servers = slave1/db/name/pw:slave2/db/name/pw:master/db/name/pw
+
+    In an updating lookup, you could then write
+
+      ${lookup mysql{servers=master; UPDATE ...}
+
+    If, on the other hand, the master is not to be used for reading lookups:
+
+      pgsql_servers = slave1/db/name/pw:slave2/db/name/pw
+
+    you can still update the master by
+
+      ${lookup pgsql{servers=master/db/name/pw; UPDATE ...}
+
+11. The message_body_newlines option (default FALSE, for backwards
+    compatibility) can be used to control whether newlines are present in
+    $message_body and $message_body_end. If it is FALSE, they are replaced by
+    spaces.
