+Since version 4.91
+------------------
+
+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/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.
+
+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/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/14 Bug 2284: Fix DKIM signing for body lines starting with a pair of dots.
+
+JH/16 Fix ARC verification to do AS checks in reverse order.
+
+JH/18 Bug 2287: Fix the protocol name (eg utf8esmtp) for multiple messages
+      using the SMTPUTF8 option on their MAIL FROM commands, in one connection.
+      Previously the "utf8" would be re-prepended for every additional message.
+
+JH/20 Bug 2296: Fix cutthrough for >1 address redirection.  Previously only
+      one parent address was copied, and bogus data was used at delivery-logging
+      time.  Either a crash (after delivery) or bogus log data could result.
+      Discovery and analysis by Tim Stewart.
+
+JH/23 Bug 2318: Fix the noerror command within filters.  It wasn't working.
+      The ignore_error flag wasn't being returned from the filter subprocess so
+      was not set for later routers.  Investigation and fix by Matthias Kurz.
+
+JH/26 Bug 2311: Fix DANE-TA verification under GnuTLS.  Previously it was also
+      requiring a known-CA anchor certificate; make it now rely entirely on the
+      TLSA as an anchor.  Checking the name on the leaf cert against the name
+      on the A-record for the host is still done for TA (but not for EE mode).
+
+JH/27 Fix logging of proxy address.  Previously, a pointless "PRX=[]:0" would be
+      included in delivery lines for non-proxied connections, when compiled with
+      SUPPORT_SOCKS and running with proxy logging enabled.
+
+JH/31 Fix a bad use of a copy function, which could be used to pointlessly
+      copy a string over itself.  The library routine is documented as not
+      supporting overlapping copies, and on MacOS it actually raised a SIGABRT.
+
+JH/33 Bug 2338: Fix the cyrus-sasl authenticator to fill in the
+      $authenticated_fail_id variable on authentication failure.  Previously
+      it was unset.
+
+JH/36 Harden the handling of string-lists.  When a list consisted of a sole
+      "<" character, which should be a list-separator specification, we walked
+      off past the nul-terimation.
+
+AM/01 GnuTLS: repeat lowlevel read and write operations while they return error
+      codes indicating retry.  Under TLS1.3 this becomes required.
+
+JH/41 Fix the loop reading a message header line to check for integer overflow,
+      and more-often against header_maxsize.  Previously a crafted message could
+      induce a crash of the recive process; now the message is cleanly rejected.
+
+JH/42 Bug 2366: Fix the behaviour of the dkim_verify_signers option.  It had
+      been totally disabled for all of 4.91.  Discovery and fix by "Mad Alex".
+
+JH/43 Fix CVE-2019-10149
+

 JH/37 Bug 2255: Revert the disable of the OpenSSL session caching.  This
       triggered odd behaviour from Outlook Express clients.

+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.
