+JH/14 Fix logging of errors under PIPELINING.  Previously the log line giving
+      the relevant preceding SMTP command did not note the pipelining mode.
+
+JH/15 Fix counting of empty lines in $body_linecount and $message_linecount.
+      Previously they were not counted.

+JH/18 Bug 1867: make the fail_defer_domains option on a dnslookup router work
+      for missing MX records.  Previously it only worked for missing A records.
+
+JH/19 Bug 1850: support Radius libraries that return REJECT_RC.
+
+JH/20 Bug 1872: Ensure that acl_smtp_notquit is run when the connection drops
+      after the data-go-ahead and data-ack.  Patch from Jason Betts.
+
+JH/21 Bug 1846: Send DMARC forensic reports for reject and quaratine results,
+      even for a "none" policy.  Patch from Tony Meyer.
+
+JH/22 Fix continued use of a connection for further deliveries. If a port was
+      specified by a router, it must also match for the delivery to be
+      compatible.
+
+JH/23 Bug 1874: fix continued use of a connection for further deliveries.
+      When one of the recipients of a message was unsuitable for the connection
+      (has no matching addresses), we lost track of needing to mark it
+      deferred.  As a result mail would be lost.
+
+JH/24 Bug 1832: Log EHLO response on getting conn-close response for HELO.
+
+JH/25 Decoding ACL controls is now done using a binary search; the source code
+      takes up less space and should be simpler to maintain.  Merge the ACL
+      condition decode tables also, with similar effect.
+
+JH/26 Fix problem with one_time used on a redirect router which returned the
+      parent address unchanged.  A retry would see the parent address marked as
+      delivered, so not attempt the (identical) child.  As a result mail would
+      be lost.
+
+JH/27 Fix a possible security hole, wherein a process operating with the Exim
+      UID can gain a root shell.  Credit to http://www.halfdog.net/ for
+      discovery and writeup.  Ubuntu bug 1580454; no bug raised against Exim
+      itself :(
+
+JH/28 Enable {spool,log} filesystem space and inode checks as default.
+      Main config options check_{log,spool}_{inodes,space} are now
+      100 inodes, 10MB unless set otherwise in the configuration.
+
+JH/29 Fix the connection_reject log selector to apply to the connect ACL.
+      Previously it only applied to the main-section connection policy
+      options.
+
+JH/30 Bug 1897: fix callouts connection fallback from TLS to cleartext.
+
+PP/01 Changed default Diffie-Hellman parameters to be Exim-specific, created
+      by me.  Added RFC7919 DH primes as an alternative.
+
+PP/02 Unbreak build via pkg-config with new hash support when crypto headers
+      are not in the system include path.
+
+JH/31 Fix longstanding bug with aborted TLS server connection handling.  Under
+      GnuTLS, when a session startup failed (eg because the client disconnected)
+      Exim did stdio operations after fclose.  This was exposed by a recent
+      change which nulled out the file handle after the fclose.
+
+JH/32 Bug 1909: Fix OCSP proof verification for cases where the proof is
+      signed directly by the cert-signing cert, rather than an intermediate
+      OCSP-signing cert.  This is the model used by LetsEncrypt.
+
+JH/33 Bug 1914: Ensure socket is nonblocking before draining after SMTP QUIT.
+
+HS/01 Fix leak in verify callout under GnuTLS, about 3MB per recipient on
+      an incoming connection.
+
+HS/02 Bug 1802: Do not half-close the connection after sending a request
+      to rspamd.
