+TF/01 $received_time is a new expansion variable containing the time and date
+      as a number of seconds since the start of the Unix epoch when the
+      current message was received.
+
+PH/03 There is a new value for RADIUS_LIB_TYPE that can be set in
+      Local/Makefile. It is RADIUSCLIENTNEW, and it requests that the new API,
+      in use from radiusclient 0.4.0 onwards, be used. It does not appear to be
+      possible to detect the different versions automatically.
+
+PH/04 There is a new option called acl_not_smtp_mime that allows you to scan
+      MIME parts in non-SMTP messages. It operates in exactly the same way as
+      acl_smtp_mime
+
+PH/05 It is now possible to redefine a macro within the configuration file.
+      The macro must have been previously defined within the configuration (or
+      an included file). A definition on the command line using the -D option
+      causes all definitions and redefinitions within the file to be ignored.
+      In other words, -D overrides any values that are set in the file.
+      Redefinition is specified by using '==' instead of '='. For example:
+
+        MAC1 =  initial value
+        ...
+        MAC1 == updated value
+
+      Redefinition does not alter the order in which the macros are applied to
+      the subsequent lines of the configuration file. It is still the same
+      order in which the macros were originally defined. All that changes is
+      the macro's value. Redefinition makes it possible to accumulate values.
+      For example:
+
+        MAC1 =  initial value
+        ...
+        MAC1 == MAC1 and something added
+
+      This can be helpful in situations where the configuration file is built
+      from a number of other files.
+
+PH/06 Macros may now be defined or redefined between router, transport,
+      authenticator, or ACL definitions, as well as in the main part of the
+      configuration. They may not, however, be changed within an individual
+      driver or ACL, or in the local_scan, retry, or rewrite sections of the
+      configuration.
+
+PH/07 $acl_verify_message is now set immediately after the failure of a
+      verification in an ACL, and so is available in subsequent modifiers. In
+      particular, the message can be preserved by coding like this:
+
+         warn  !verify = sender
+               set acl_m0 = $acl_verify_message
+
+      Previously, $acl_verify_message was set only while expanding "message"
+      and "log_message" when a very denied access.
+
+PH/08 The redirect router has two new options, sieve_useraddress and
+      sieve_subaddress. These are passed to a Sieve filter to specify the :user
+      and :subaddress parts of an address. Both options are unset by default.
+      However, when a Sieve filter is run, if sieve_useraddress is unset, the
+      entire original local part (including any prefix or suffix) is used for
+      :user. An unset subaddress is treated as an empty subaddress.
+
+PH/09 Quota values can be followed by G as well as K and M.
+
+PH/10 $message_linecount is a new variable that contains the total number of
+      lines in the header and body of the message. Compare $body_linecount,
+      which is the count for the body only. During the DATA and
+      content-scanning ACLs, $message_linecount contains the number of lines
+      received. Before delivery happens (that is, before filters, routers, and
+      transports run) the count is increased to include the Received: header
+      line that Exim standardly adds, and also any other header lines that are
+      added by ACLs. The blank line that separates the message header from the
+      body is not counted. Here is an example of the use of this variable in a
+      DATA ACL:
+
+        deny message   = Too many lines in message header
+             condition = \
+               ${if <{250}{${eval: $message_linecount - $body_linecount}}}
+
+      In the MAIL and RCPT ACLs, the value is zero because at that stage the
+      message has not yet been received.
