 JH/12 Add optional authenticated_sender logging to A= and a log_selector
       for control.
 
+PP/12 Unbreak server_set_id for NTLM/SPA auth, broken by 4.80 PP/29.
+
+PP/13 Dovecot auth: log better reason to rejectlog if Dovecot did not
+      advertise SMTP AUTH mechanism to us, instead of a generic
+      protocol violation error.  Also, make Exim more robust to bad
+      data from the Dovecot auth socket.
+
+TF/01 Fix ultimate retry timeouts for intermittently deliverable recipients.
+
+      When a queue runner is handling a message, Exim first routes the
+      recipient addresses, during which it prunes them based on the retry
+      hints database. After that it attempts to deliver the message to
+      any remaining recipients. It then updates the hints database using
+      the retry rules.
+
+      So if a recipient address works intermittently, it can get repeatedly
+      deferred at routing time. The retry hints record remains fresh so the
+      address never reaches the final cutoff time.
+
+      This is a fairly common occurrence when a user is bumping up against
+      their storage quota. Exim had some logic in its local delivery code
+      to deal with this. However it did not apply to per-recipient defers
+      in remote deliveries, e.g. over LMTP to a separate IMAP message store.
+
+      This change adds a proper retry rule check during routing so that the
+      final cutoff time is checked against the message's age. We only do
+      this check if there is an address retry record and there is not a
+      domain retry record; this implies that previous attempts to handle
+      the address had the retry_use_local_parts option turned on. We use
+      this as an approximation for the destination being like a local
+      delivery, as in LMTP.
+
+      I suspect this new check makes the old local delivery cutoff check
+      redundant, but I have not verified this so I left the code in place.
+
+TF/02 Correct gecos expansion when From: is a prefix of the username.
+
+      Test 0254 submits a message to Exim with the header
+
+        Resent-From: f
+
+      When I ran the test suite under the user fanf2, Exim expanded
+      the header to contain my full name, whereas it should have added
+      a Resent-Sender: header. It erroneously treats any prefix of the
+      username as equal to the username.
+
+      This change corrects that bug.
+
+GF/01 DCC debug and logging tidyup
+      Error conditions log to paniclog rather than rejectlog.
+      Debug lines prefixed by "DCC: " to remove any ambiguity.
+
+TF/03 Avoid unnecessary rebuilds of lookup-related code.
+
+PP/14 Fix OCSP reinitialisation in SNI handling for Exim/TLS as server.
+      Bug spotted by Jeremy Harris; was flawed since initial commit.
+      Would have resulted in OCSP responses post-SNI triggering an Exim
+      NULL dereference and crash.

+JH/13 Add $router_name and $transport_name variables.  Bugzilla 308.
+
+PP/15 Define SIOCGIFCONF_GIVES_ADDR for GNU Hurd.

+JH/14 SMTP PRDR (http://www.eric-a-hall.com/specs/draft-hall-prdr-00.txt).
+      Server implementation by Todd Lyons, client by JH.
+      Only enabled when compiled with EXPERIMENTAL_PRDR.  A new
+      config variable "prdr_enable" controls whether the server
+      advertises the facility.  If the client requests PRDR a new
+      acl_data_smtp_prdr ACL is called once for each recipient, after
+      the body content is received and before the acl_smtp_data ACL.
+      The client is controlled by bolth of: a hosts_try_prdr option
+      on the smtp transport, and the server advertisement.
+      Default client logging of deliveries and rejections involving
+      PRDR are flagged with the string "PRDR".
+
+PP/16 Fix problems caused by timeouts during quit ACLs trying to double
+      fclose().  Diagnosis by Todd Lyons.
+
+PP/17 Update configure.default to handle IPv6 localhost better.
+      Patch by Alain Williams (plus minor tweaks).
+      Bugzilla 880.
+
+PP/18 OpenSSL made graceful with empty tls_verify_certificates setting.
+      This is now consistent with GnuTLS, and is now documented: the
+      previous undocumented portable approach to treating the option as
+      unset was to force an expansion failure.  That still works, and
+      an empty string is now equivalent.
+
+PP/19 Renamed DNSSEC-enabling option to "dns_dnssec_ok", to make it
+      clearer that Exim is using the DO (DNSSEC OK) EDNS0 resolver flag,
+      not performing validation itself.
+
+PP/20 Added force_command boolean option to pipe transport.
+      Patch from Nick Koston, of cPanel Inc.
