+Version 4.77
+------------
+
+ 1. New options for the ratelimit ACL condition: /count= and /unique=.
+    The /noupdate option has been replaced by a /readonly option.
+
+ 2. The SMTP transport's protocol option may now be set to "smtps", to
+    use SSL-on-connect outbound.
+
+ 3. New variable $av_failed, set true if the AV scanner deferred; ie, when
+    there is a problem talking to the AV scanner, or the AV scanner running.
+
+
+Version 4.76
+------------
+
+ 1. The global option "dns_use_edns0" may be set to coerce EDNS0 usage on
+    or off in the resolver library.
+
+
+Version 4.75
+------------
+
+ 1. In addition to the existing LDAP and LDAP/SSL ("ldaps") support, there
+    is now LDAP/TLS support, given sufficiently modern OpenLDAP client
+    libraries.  The following global options have been added in support of
+    this: ldap_ca_cert_dir, ldap_ca_cert_file, ldap_cert_file, ldap_cert_key,
+    ldap_cipher_suite, ldap_require_cert, ldap_start_tls.
+
+ 2. The pipe transport now takes a boolean option, "freeze_signal", default
+    false.  When true, if the external delivery command exits on a signal then
+    Exim will freeze the message in the queue, instead of generating a bounce.
+
+ 3. Log filenames may now use %M as an escape, instead of %D (still available).
+    The %M pattern expands to yyyymm, providing month-level resolution.
+
+ 4. The $message_linecount variable is now updated for the maildir_tag option,
+    in the same way as $message_size, to reflect the real number of lines,
+    including any header additions or removals from transport.
+
+ 5. When contacting a pool of SpamAssassin servers configured in spamd_address,
+    Exim now selects entries randomly, to better scale in a cluster setup.
+
+
+Version 4.74
+------------
+
+ 1. SECURITY FIX: privilege escalation flaw fixed. On Linux (and only Linux)
+    the flaw permitted the Exim run-time user to cause root to append to
+    arbitrary files of the attacker's choosing, with the content based
+    on content supplied by the attacker.
+
+ 2. Exim now supports loading some lookup types at run-time, using your
+    platform's dlopen() functionality.  This has limited platform support
+    and the intention is not to support every variant, it's limited to
+    dlopen().  This permits the main Exim binary to not be linked against
+    all the libraries needed for all the lookup types.
