+
+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.

 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.

       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.
