+      for RCPT commands, for example. But see also PH/45 below.
+
+PH/08 The ${eval expansion now supports % as a "remainder" operator.
+
+PH/09 There is a new ACL condition "verify = not_blind". It checks that there
+      are no blind (bcc) recipients in the message. Every envelope recipient
+      must appear either in a To: header line or in a Cc: header line for this
+      condition to be true. Local parts are checked case-sensitively; domains
+      are checked case-insensitively. If Resent-To: or Resent-Cc: header lines
+      exist, they are also checked. This condition can be used only in a DATA
+      or non-SMTP ACL.
+
+      There are, of course, many legitimate messages that make use of blind
+      (bcc) recipients. This check should not be used on its own for blocking
+      messages.
+
+PH/10 There is a new ACL control called "suppress_local_fixups". This applies
+      to locally submitted (non TCP/IP) messages, and is the complement of
+      "control = submission". It disables the fixups that are normally applied
+      to locally-submitted messages. Specifically:
+
+      (a) Any Sender: header line is left alone (in this respect, it's a
+          dynamic version of local_sender_retain).
+
+      (b) No Message-ID:, From:, or Date: headers are added.
+
+      (c) There is no check that From: corresponds to the actual sender.
+
+      This feature may be useful when a remotely-originated message is
+      accepted, passed to some scanning program, and then re-submitted for
+      delivery. It means that all four possibilities can now be specified:
+
+      (1) Locally submitted, fixups applies: the default.
+      (2) Locally submitted, no fixups applied: use control =
+          suppress_local_fixups.
+      (3) Remotely submitted, no fixups applied: the default.
+      (4) Remotely submitted, fixups applied: use control = submission.
+
+PH/11 There is a new log selector, "unknown_in_list", which provokes a log
+      entry when the result of a list match is failure because a DNS lookup
+      failed.
+
+PH/12 There is a new variable called $smtp_command which contains the full SMTP
+      command (compare $smtp_command_argument - see PH/07 above). This makes it
+      possible to distinguish between HELO and EHLO, and also between things
+      like "MAIL FROM:<>" and "MAIL FROM: <>".
+
+TF/01 There's a new script in util/ratelimit.pl which extracts sending
+      rates from log files, to assist with choosing appropriate settings
+      when deploying the ratelimit ACL condition.
