+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.
