+Version 4.63
+------------
+
+1. There is a new Boolean option called filter_prepend_home for the redirect
+   router. It defaults true, for backward compatibility. If a "save" command in
+   an Exim filter has a relative path for its argument, and $home is defined,
+   it is automatically prepended to the relative path. This action can now be
+   prevented by setting filter_prepend_home false.
+
+2. There is a new acl, set by acl_not_smtp_start, which is run right at the
+   start of receiving a non-SMTP message, before any of the message has been
+   read. (This is the analogue of the acl_smtp_predata ACL for SMTP input.) The
+   result of this ACL is ignored; it cannot be used to reject a message. If
+   you really need to, you could set a value in an ACL variable here and reject
+   based on that in the acl_not_smtp ACL. However, this ACL can be used to set
+   controls, and in particular, it can be used to set control=suppress_local_
+   fixups, which cannot be used in the acl_not_smtp ACL because by the time
+   that ACL is run, it is too late. When the acl_not_smtp_start ACL is run, the
+   sender and recipients are known, so the "senders" and "sender_domains"
+   conditions and $sender_address and $recipients variables can be used.
+   Variables such as $authenticated_ sender are also available. It is possible
+   to specify added header lines in this ACL.
+
+3. 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.

 
 

-Version 4.51
+
+Version 4.62

-PH/01. The format in which GnuTLS parameters are written to the gnutls-param
-       file in the spool directory has been changed. This change has been made
-       to alleviate problems that some people had with the generation of the
-       parameters by Exim when /dev/random was exhausted. In this situation,
-       Exim would hang until /dev/random acquired some more entropy.
+1. The ${readsocket expansion item now supports Internet domain sockets as well
+   as Unix domain sockets. If the first argument begins "inet:", it must be of
+   the form "inet:host:port". The port is mandatory; it may be a number or the
+   name of a TCP port in /etc/services. The host may be a name, or it may be an
+   IP address. An ip address may optionally be enclosed in square brackets.
+   This is best for IPv6 addresses. For example:

 
 

-       The new code exports and imports the DH and RSA parameters in PEM
-       format. This means that the parameters can be generated externally using
-       the certtool command that is part of GnuTLS.
+     ${readsocket{inet:[::1]:1234}{<request data>}...

 
 

-       To replace the parameters with new ones, instead of deleting the file
-       and letting Exim re-create it, you can generate new parameters using
-       certtool and, when this has been done, replace Exim's cache file by
-       renaming. The relevant commands are something like this:
+   Only a single host name may be given, but if looking it up yield more than
+   one IP address, they are each tried in turn until a connection is made. Once
+   a connection has been made, the behaviour is as for ${readsocket with a Unix
+   domain socket.

 
 

-         # rm -f new.params
-         # touch new.params
-         # chown exim:exim new.params
-         # chmod 0400 new.params
-         # certtool --generate-privkey --bits 512 >new.params
-         # echo "" >>new.params
-         # certtool --generate-dh-params --bits 1024 >> new.params
-         # mv new.params params
+2. If a redirect router sets up file or pipe deliveries for more than one
+   incoming address, and the relevant transport has batch_max set greater than
+   one, a batch delivery now occurs.

 
 

-       If Exim never has to generate the parameters itself, the possibility of
-       stalling is removed.
+3. The appendfile transport has a new option called maildirfolder_create_regex.
+   Its value is a regular expression. For a maildir delivery, this is matched
+   against the maildir directory; if it matches, Exim ensures that a
+   maildirfolder file is created alongside the new, cur, and tmp directories.

 
 
 
 

-Version 4.50
+Version 4.61

 ------------
 
 ------------
 

-The documentation is up-to-date for the 4.50 release.
+The documentation is up-to-date for the 4.61 release. Major new features since
+the 4.60 release are:
+
+. An option called disable_ipv6, to disable the use of IPv6 completely.
+
+. An increase in the number of ACL variables to 20 of each type.
+
+. A change to use $auth1, $auth2, and $auth3 in authenticators instead of $1,
+  $2, $3, (though those are still set) because the numeric variables get used
+  for other things in complicated expansions.
+
+. The default for rfc1413_query_timeout has been changed from 30s to 5s.
+
+. It is possible to use setclassresources() on some BSD OS to control the
+  resources used in pipe deliveries.
+
+. A new ACL modifier called add_header, which can be used with any verb.
+
+. More errors are detectable in retry rules.
+
+There are a number of other additions too.
+
+
+Version 4.60
+------------
+
+The documentation is up-to-date for the 4.60 release. Major new features since
+the 4.50 release are:
+
+. Support for SQLite.
+
+. Support for IGNOREQUOTA in LMTP.
+
+. Extensions to the "submission mode" features.
+
+. Support for Client SMTP Authorization (CSA).
+
+. Support for ratelimiting hosts and users.
+
+. New expansion items to help with the BATV "prvs" scheme.
+
+. A "match_ip" condition, that matches an IP address against a list.
+
+There are many more minor changes.
