-Since Exim version 4.90
------------------------
+Exim version 4.92
+-----------------
+
+JH/01 Remove code calling the customisable local_scan function, unless a new
+      definition "HAVE_LOCAL_SCAN=yes" is present in the Local/Makefile.
+
+JH/02 Bug 1007: Avoid doing logging from signal-handlers, as that can result in
+      non-signal-safe functions being used.
+
+JH/03 Bug 2269: When presented with a received message having a stupidly large
+      number of DKIM-Signature headers, disable DKIM verification to avoid
+      a resource-consumption attack.  The limit is set at twenty.
+
+JH/04 Add variables $arc_domains, $arc_oldest_pass for ARC verify.  Fix the
+      report of oldest_pass in ${authres } in consequence, and separate out
+      some descriptions of reasons for verification fail.
+
+JH/05 Bug 2273: Cutthrough delivery left a window where the received messsage
+      files in the spool were present and unlocked.  A queue-runner could spot
+      them, resulting in a duplicate delivery.  Fix that by doing the unlock
+      after the unlink.  Investigation by Tim Stewart.  Take the opportunity to
+      add more error-checking on spoolfile handling while that code is being
+      messed with.
+
+PP/01 Refuse to open a spool data file (*-D) if it's a symlink.
+      No known attacks, no CVE, this is defensive hardening.
+
+JH/06 Bug 2275: The MIME ACL unlocked the received message files early, and
+      a queue-runner could start a delivery while other operations were ongoing.
+      Cutthrough delivery was a common victim, resulting in duplicate delivery.
+      Found and investigated by Tim Stewart.  Fix by using the open message data
+      file handle rather than opening another, and not locally closing it (which
+      releases a lock) for that case, while creating the temporary .eml format
+      file for the MIME ACL.  Also applies to "regex" and "spam" ACL conditions.
+
+JH/07 Bug 177: Make a random-recipient callout success visible in ACL, by setting
+      $sender_verify_failure/$recipient_verify_failure to "random".
+
+JH/08 When generating a selfsigned cert, use serial number 1 since zero is not
+      legitimate.
+
+JH/09 Bug 2274: Fix logging of cmdline args when starting in an unlinked cwd.
+      Previously this would segfault.
+
+JH/10 Fix ARC signing for case when DKIM signing failed.  Previously this would
+      segfault.
+
+JH/11 Bug 2264: Exim now only follows CNAME chains one step by default. We'd
+      like zero, since the resolver should be doing this for us, But we need one
+      as a CNAME but no MX presence gets the CNAME returned; we need to check
+      that doesn't point to an MX to declare it "no MX returned" rather than
+      "error, loop".  A new main option is added so the older capability of
+      following some limited number of chain links is maintained.
+
+JH/12 Add client-ip info to non-pass iprev ${authres } lines.

 GF/01 DEFER rather than ERROR on redis cluster MOVED response.
 
 GF/01 DEFER rather than ERROR on redis cluster MOVED response.

-     When redis_servers is set to a list of > 1 element, and the Redis servers
-     in that list are in cluster configuration, convert the REDIS_REPLY_ERROR
-     case of MOVED into a DEFER case instead, thus moving the query onto the
-     next server in the list. For a cluster of N elements, all N servers must
-     be defined in redis_servers.

 JH/34 Re-introduce enforcement of no cutthrough delivery on transports having
       transport-filters or DKIM-signing.  The restriction was lost in the
       consolidation of verify-callout and delivery SMTP handling.

+      Extend the restriction to also cover ARC-signing.
+
+JH/35 Cutthrough: for a final-dot response timeout (and nonunderstood responses)
+      in defer=pass mode supply a 450 to the initiator.  Previously the message
+      would be spooled.
+
+PP/02 DANE: add dane_require_tls_ciphers SMTP Transport option; if unset,
+      tls_require_ciphers is used as before.
+
+HS/03 Malware Avast: Better match the Avast multiline protocol. Add
+      "pass_unscanned".  Only tmpfails from the scanner are written to
+      the paniclog, as they may require admin intervention (permission
+      denied, license issues). Other scanner errors (like decompression
+      bombs) do not cause a paniclog entry.
+
+JH/36 Fix reinitialisation of DKIM logging variable between messages.
+      Previously it was possible to log spurious information in receive log
+      lines.
+
+JH/37 Bug 2255: Revert the disable of the OpenSSL session caching.  This
+      triggered odd behaviour from Outlook Express clients.
+
+PP/03 Add util/renew-opendmarc-tlds.sh script for safe renewal of public
+      suffix list.
+
+JH/38 DKIM: accept Ed25519 pubkeys in SubjectPublicKeyInfo-wrapped form,
+      since the IETF WG has not yet settled on that versus the original
+      "bare" representation.
+
+JH/39 Fix syslog logging for syslog_timestamp=no and log_selector +millisec.
+      Previously the millisecond value corrupted the output.
+      Fix also for syslog_pid=no and log_selector +pid, for which the pid
+      corrupted the output.
