+Exim version 4.63
+-----------------
+
+When an SMTP error message is specified in a "message" modifier in an ACL, or
+in a :fail: or :defer: message in a redirect router, Exim now checks the start
+of the message for an SMTP error code. This consists of three digits followed
+by a space, optionally followed by an extended code of the form n.n.n, also
+followed by a space. If this is the case and the very first digit is the same
+as the default error code, the code from the message is used instead. If the
+very first digit is incorrect, a panic error is logged, and the default code is
+used. This is an incompatible change, but it is not expected to affect many (if
+any) configurations. It is possible to suppress the use of the supplied code in
+a redirect router by setting the smtp_error_code option false. In this case,
+any SMTP code is quietly ignored.
+
+
+Exim version 4.61
+-----------------
+
+1. The default number of ACL variables of each type has been increased to 20,
+and it's possible to compile Exim with more. You can safely upgrade to this
+release if you already have messages on the queue with saved ACL variable
+values. However, if you downgrade from this release with messages on the queue,
+any saved ACL values they may have will be lost.
+
+2. The default value for rfc1413_query_timeout has been changed from 30s to 5s.
+
+
+Exim version 4.54
+-----------------
+
+There was a problem with 4.52/TF/02 in that a "name=" option on control=
+submission terminated at the next slash, thereby not allowing for slashes in
+the name. This has been changed so that "name=" takes the rest of the string as
+its data. It must therefore be the last option.
+
+
+Version 4.53
+------------
+
+If you are using the experimental Domain Keys support, you must upgrade to
+at least libdomainkeys 0.67 in order to run this release of Exim.

 externally, so it is now possible to update the values from outside Exim. This

 you MUST delete the gnutls-params file in the spool directory, because the
 older Exim will not recognize the new format.
 
+2. When doing a callout as part of verifying an address, Exim was not paying
+attention to any local part prefix or suffix that was matched by the router
+that accepted the address. It now behaves in the same way as it does for
+delivery: the affixes are removed from the local part unless
+rcpt_include_affixes is set on the transport. If you have a configuration that
+uses prefixes or suffixes on addresses that could be used for callouts, and you
+want the affixes to be retained, you must make sure that rcpt_include_affixes
+is set on the transport.
+
+3. Bounce and delay warning messages no longer contain details of delivery
+errors, except for explicit messages (e.g. generated by :fail:) and SMTP
+responses from remote hosts.
