+Exim version 4.87
+-----------------
+JH/01 Bug 1664: Disable OCSP for GnuTLS library versions at/before 3.3.16
+      and 3.4.4 - once the server is enabled to respond to an OCSP request
+      it does even when not requested, resulting in a stapling non-aware
+      client dropping the TLS connection.
+
+TF/01 Code cleanup: Overhaul the debug_selector and log_selector machinery to
+      support variable-length bit vectors. No functional change.
+
+TF/02 Improve the consistency of logging incoming and outgoing interfaces.
+      The I= interface field on outgoing lines is now after the H= remote
+      host field, same as incoming lines. There is a separate
+      outgoing_interface log selector which allows you to disable the
+      outgoing I= field.
+
+JH/02 Bug 728: Close logfiles after a daemon-process "exceptional" log write.
+      If not running log_selector +smtp_connection the mainlog would be held
+      open indefinitely after a "too many connections" event, including to a
+      deleted file after a log rotate. Leave the per net connection logging
+      leaving it open for efficiency as that will be quickly detected by the
+      check on the next write.
+
+HS/01 Bug 1671: Fix post transport crash.
+      Processing the wait-<transport> messages could crash the delivery
+      process if the message IDs didn't exist for some reason. When
+      using 'split_spool_directory=yes' the construction of the spool
+      file name failed already, exposing the same netto behaviour.
+
+JH/03 Bug 425: Capture substrings in $regex1, $regex2 etc from regex &
+      mime_regex ACL conditions.
+
+JH/04 Bug 1686: When compiled with EXPERIMENTAL_DSN_INFO: Add extra information
+      to DSN fail messages (bounces): remote IP, remote greeting, remote response
+      to HELO, local diagnostic string.
+
+JH/05 Downgrade message for a TLS-certificate-based authentication fail from
+      log line to debug.  Even when configured with a tls authenticator many
+      client connections are expected to not authenticate in this way, so
+      an authenticate fail is not an error.
+
+HS/02 Add the Exim version string to the process info.  This way exiwhat
+      gives some more detail about the running daemon.
+
+JH/06 Bug 1395: time-limit cacheing of DNS lookups, to the TTL value.  This may
+      matter for fast-change records such as DNSBLs.

 JH/25 Bug 466: Add RFC2322 support for MIME attachment filenames.

+JH/27 Bug 286: Support SOA lookup in dnsdb lookups.
+
+JH/28 Bug 1588: Do not use the A lookup following an AAAA for setting the FQDN.
+      Normally benign, it bites when the pair was led to by a CNAME;
+      modern usage is to not canoicalize the domain to a CNAME target
