+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/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.
