+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.
+
+4. There is a new parameter for LDAP lookups called "referrals", which takes
+ one of the settings "follow" (the default) or "nofollow". The latter stops
+ the LDAP library from trying to follow referrals issued by the LDAP server.
+
+
+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.
