+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.
+
+
+Version 4.62
+------------
+
+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:
+
+     ${readsocket{inet:[::1]:1234}{<request data>}...
+
+   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.
+
+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.
+
+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 4.61
 ------------
 
 Version 4.61
 ------------
 

-PH/01 There is a new global option called disable_ipv6, which does exactly what
-      its name implies. If set true, even if the Exim binary has IPv6 support,
-      no IPv6 activities take place. AAAA records are never looked up for host
-      names given in manual routing data or elsewhere. AAAA records that are
-      received from the DNS as additional data for MX records are ignored. Any
-      IPv6 addresses that are listed in local_interfaces, manualroute route
-      data, etc. are also ignored. If IP literals are enabled, the ipliteral
-      router declines to handle IPv6 literal addresses.
-
-PH/02 There are now 20 of each type of ACL variable by default (instead of 10).
-      It is also possible to change the numbers by setting ACL_CVARS and/or
-      ACL_MVARS in Local/Makefile. Backward compatibility is maintained if you
-      upgrade to this release with existing messages containing ACL variable
-      settings on the queue. However, going in the other direction
-      (downgrading) will not be compatible; the values of ACL variables will be
-      lost.
-
-PH/03 If quota_warn_message contains a From: header, Exim now refrains from
-      adding the default one. Similarly, if it contains a Reply-To: header, the
-      errors_reply_to option, if set, is not used.
-
-PH/04 The variables $auth1, $auth2, $auth3 are now available in authenticators,
-      containing the same values as $1, $2, $3. The new variables are provided
-      because the numerical variables can be reset during string expansions
-      (for example, during a "match" operation) and so may lose the
-      authentication data. The preferred variables are now the new ones, with
-      the use of the numerical ones being deprecated, though the support will
-      not be removed, at least, not for a long time.
-
-PH/05 The "control=freeze" ACL modifier can now be followed by /no_tell. If
-      the global option freeze_tell is set, it is ignored for the current
-      message (that is, nobody is told about the freezing), provided all the
-      "control=freeze" modifiers that are obeyed in the current message have
-      the /no_tell option.
-
-PH/06 In both GnuTLS and OpenSSL, an expansion of tls_privatekey that results
-      in an empty string is now treated as unset.
-
-PH/07 There is a new log selector called sender_verify_fail, which is set by
-      default. If it is unset, the separate log line that gives details of a
-      sender verification failure is not written. Log lines for the rejection
-      of SMTP commands (e.g. RCPT) contain just "sender verify failed", so some
-      detail is lost.
-
-PH/08 The default for dns_check_names_pattern now allows slashes within names,
-      as there are now some PTR records that contain slashes. This check is
-      only to protect against broken name servers that fall over on strange
-      characters, so the fact that it applies to all lookups doesn't matter.
-
-PH/09 The default for rfc4131_query_timeout has been changed from 30s to 5s.
-
-PH/10 When compiled on FreeBSD, NetBSD, or BSD/OS, the pipe transport has a new
-      Boolean option called use_classresources, defaulting false. If it is set
-      true, the setclassresources() function is used to set resource limits
-      when a pipe transport is run to perform a delivery. The limits for the
-      uid under which the pipe is to run are obtained from the login class
-      database.
-
-PH/11 If retry_interval_max is set greater than 24 hours, it is quietly reset
-      to 24 hours. This avoids potential overflow problems when processing G
-      and H retry rules, and it seems reasonable to require a retry at least
-      once a day.
-
-PH/12 When the plaintext authenticator is running as a client, the server
-      challenges are now checked to ensure they are valid base64 strings. The
-      default action on failure is to abort the authentication. However, if
-      client_ignore_invalid_base64 is set true, invalid responses are ignored.
-
-PH/13 When the plaintext authenticator is running as a client, the challenges
-      from the server are placed in $auth1, $auth2, etc. as they are received.
-      Thus, the challege that is received in response to sending the first
-      string (with the AUTH command) can be used in the expansion of the second
-      string, and so on. Currently, up to 3 challenge strings are available in
-      this way. If an invalid base64 string is received when client_ignore_
-      invalid_base64 is set, an empty string is put in the $auth<n> variable.
-
-PH/14 Messages created by the autoreply transport now contain a References:
-      header. This is constructed in accordance with rules that are described
-      in section 3.64 of RFC 2822, which states that replies should contain
-      such a header line, and section 3.14 of RFC 3834, which states that
-      automatic responses are not different in this respect. However, because
-      some mail processing software does not cope well with very long header
-      lines, no more than 12 message IDs are copied from the References: header
-      line in the incoming message. If there are more than 12, the first one
-      and then the final 11 are copied, before adding the message ID of the
-      incoming message.
+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.
