 JH/13 Bug 2386: Fix builds with Dane under LibreSSL 2.9.0 onward.  Some old
       API was removed, so update to use the newer ones.
 
+JH/14 Bug 1891: Close the log file if receiving a non-smtp message, without
+      any timeout set, is taking a long time.  Previously we would hang on to a
+      rotated logfile "forever" if the input was arriving with long gaps
+      (a previous attempt to fix addressed lack, for a long time, of initial
+      input).
+
+HS/01 Bug 2390: Use message_id for tempfile creation to avoid races in a
+      shared (NFS) environment. The length of the tempfile name is now
+      4 + 16 ("hdr.$message_exim_id") which might break on file
+      systems which restrict the file name length to lower values.
+      (It was "hdr.$pid".)

+HS/01 Bug 2390: Use message_id for tempfile creation to avoid races in a
+      shared (NFS) environment.
+
+HS/02 Bug 2392: exigrep does case sensitive *option* processing (as it
+      did for all versions <4.90). Notably -M, -m, --invert, -I may be
+      affected.
+
+JH/15 Use unsigned when creating bitmasks in macros, to avoid build errors
+      on some platforms for bit 31.
+
+JH/16 GnuTLS: rework ciphersuite strings under recent library versions.  Thanks
+      to changes apparently associated with TLS1.3 handling some of the APIs
+      previously used were either nonfunctional or inappropriate.  Strings
+      like TLS1.3:ECDHE_SECP256R1__RSA_PSS_RSAE_SHA256__AES_256_GCM__AEAD:256
+      and TLS1.2:ECDHE_SECP256R1__RSA_SHA256__AES_128_CBC__SHA256:128 replace
+      the previous TLS1.2:ECDHE_RSA_AES_256_GCM_SHA384:256 .
+      This affects log line X= elements, the $tls_{in,out}_cipher variables,
+      and the use of specific cipher names in the encrypted= ACL condition.
+
+JH/17 OpenSSL: the default openssl_options now disables ssl_v3.
+
+JH/18 GnuTLS: fix $tls_out_ocsp under hosts_request_ocsp. Previously the
+      verification result was not updated unless hosts_require_ocsp applied.
+
+JH/19 Bug 2398: fix listing of a named-queue.  Previously, even with the option
+      queue_list_requires_admin set to false, non-admin users were denied the
+      facility.
+
+JH/20 Bug 2389: fix server advertising of usable certificates, under GnuTLS in
+      directory-of-certs mode.  Previously they were advertised despite the
+      documentation.
+
+JH/21 The smtp transport option "hosts_noproxy_tls" is now unset by default.
+      A single TCP connection by a client will now hold a TLS connection open
+      for multiple message deliveries, by default.  Previoud the default was to
+      not do so.
+
+JH/22 The smtp transport option "hosts_try_dane" now enables all hosts by
+      default.  If built with the facility, DANE will be used.  The facility
+      SUPPORT_DANE is now enabled in the prototype build Makefile "EDITME".
+
+JH/23 The build default is now for TLS to be included; the SUPPORT_TLS define
+      is replaced with DISABLE_TLS.  Either USE_GNUTLS or (the new) USE_OPENSSL
+      must be defined and you must still, unless you define DISABLE_TLS, manage
+      the the include-dir and library-file requirements that go with that
+      choice.  Non-TLS builds are still supported.
+
+JH/24 Fix duplicated logging of peer name/address, on a transport connection-
+      reject under TFO.
+
+JH/25 The smtp transport option "hosts_try_fastopen" now enables all hosts by
+      default.  If the platfor supports and has the facility enabled, it will
+      be requested on all coneections.
