-JH/05 Bug 2017: Fix DKIM verification in -bh test mode.  The data feed into
+JH/05 Have the EHLO response advertise VRFY, if there is a vrfy ACL defined.
+      Previously we did not; the RFC seems ambiguous and VRFY is not listed
+      by IANA as a service extension.  However, John Klensin suggests that we
+      should.

+JH/06 Bug 2017: Fix DKIM verification in -bh test mode.  The data feed into

       the dkim code may be unix-mode line endings rather than smtp wire-format
       CRLF, so prepend a CR to any bare LF.

+JH/07 Rationalise the coding for callout smtp conversations and transport ones.
+      As a side-benfit, callouts can now use PIPELINING hence fewer round-trips.
+
+JH/08 Bug 2016: Fix DKIM verification vs. CHUNKING.  Any BDAT commands after
+      the first were themselves being wrongly included in the feed into dkim
+      processing; with most chunk sizes in use this resulted in an incorrect
+      body hash calculated value.
+
+JH/09 Bug 2014: permit inclusion of a DKIM-Signature header in a received
+      DKIM signature block, for verification.  Although advised against by
+      standards it is specifically not ruled illegal.
+
+JH/10 Bug 2025: Fix reception of (quoted) local-parts with embedded spaces.
+
+JH/11 Bug 2029: Fix crash in DKIM verification when a message signature block is
+      missing a body hash (the bh= tag).
+
+JH/12 Bug 2018: Re-order Proxy Protocol startup versus TLS-on-connect startup.
+      It seems that HAProxy sends the Proxy Protocol information in clear and
+      only then does a TLS startup, so do the same.
+
+JH/13 Bug 2027: Avoid attempting to use TCP Fast Open for non-transport client
+      TCP connections (such as for Spamd) unless the daemon successfully set
+      Fast Open mode on its listening sockets.  This fixes breakage seen on
+      too-old kernels or those not configured for Fast Open, at the cost of
+      requiring both directions being enabled for TFO, and TFO never being used
+      by non-daemon-related Exim processes.
+
+JH/14 Bug 2000: Reject messages recieved with CHUNKING but with malformed line
+      endings, at least on the first header line.  Try to canonify any that get
+      past that check, despite the cost.
+
+JH/15 Angle-bracket nesting (an error inserted by broken sendmails) levels are
+      now limited to an arbitrary five deep, while parsing addresses with the
+      strip_excess_angle_brackets option enabled.
+
+PP/03 Bug 2018: For Proxy Protocol and TLS-on-connect, do not over-read and
+      instead leave the unprompted TLS handshake in socket buffer for the
+      TLS library to consume.
+
+PP/04 Bug 2018: Also handle Proxy Protocol v2 safely.
