 JH/21 Bug 2501: Fix init call in the heimdal authenticator.  Previously it
@@ -131,6 +132,73 @@ JH/26 Fix use of the SIZE parameter on MAIL commands, on continued connections.
       only the first would provide a SIZE.  This was due to the size information
       not being properly tracked.
 
+JH/27 Bug 2530: When operating in a timezone with sub-minute offset, such as
+      TAI (at 37 seconds currently), pretend to be in UTC for time-related
+      expansion and logging.  Previously, spurious values such as a future
+      minute could be seen.
+
+JH/28 Bug 2533: Fix expansion of ${tr } item.  When called in some situations
+      it could crash from a null-deref.  This could also affect the
+      ${addresses: } operator and ${readsock } item.
+
+JH/29 Bug 2537: Fix $mime_part_count.  When a single connection had a non-mime
+      message following a mime one, the variable was not reset.
+
+JH/30 When an pipelined-connect fails at the first response, assume incorrect
+      cached capability (perhaps the peer reneged?) and immediately retry in
+      non-pipelined mode.
+
+JH/31 Fix spurious detection of timeout while writing to transport filter.
+
+JH/32 Bug 2541: Fix segfault on bad cmdline -f (sender) argument.  Previously
+      an attempt to copy the string was made before checking it.
+
+JH/33 Fix the dsearch lookup to return an untainted result.  Previously the
+      taint of the lookup key was maintained; we now regard the presence in the
+      filesystem as sufficient validation.
+
+JH/34 Fix the readsocket expansion to not segfault when an empty "options"
+      argument is supplied.
+
+JH/35 The dsearch lookup now requires that the directory is an absolute path.
+      Previously this was not checked, and nonempty relative paths made an
+      access under Exim's current working directory.
+
+JH/36 Bug 2554: Fix msg:defer event for the hosts_max_try_hardlimit case.
+      Previously no event was raised.
+
+JH/37 Bug 2552: Fix the check on spool space during reception to use the SIZE
+      parameter supplied by the sender MAIL FROM command.  Previously it was
+      ignored, and only the check_spool_space option value for the required
+      leeway checked.
+
+JH/38 Fix $dkim_key_length.  This should, after a DKIM verification, present
+      the size of the signing public-key.  Previously it was instead giving
+      the size of the signature hash.
+
+JH/39 DKIM verification: the RFC 8301 restriction on sizes of RSA keys is now
+      the default.  See the (new) dkim_verify_min_keysizes option.
+
+JH/40 Fix a memory-handling bug: when a connection carried multiple messages
+      and an ACL use a lookup for checking either the local_part or domain,
+      stale data could be accessed.  Ensure that variable references are
+      dropped between messages.
+
+JH/41 Bug 2571: Fix SPA authenticator.  Running as a server, an offset supplied
+      by the client was not checked as pointing within response data before
+      being used.  A malicious client could thus cause an out-of-bounds read and
+      possibly gain authentication.  Fix by adding the check.
+
+JH/42 Internationalisation: change the default for downconversion in the smtp
+      transport to be "if needed".  Previously it was "as previously set" for
+      the message, which usually meant "if needed" for message-submission but
+      "no" for everything else.  However, MTAs have been seen using SMTPUTF8
+      even when the envelope addresses did not need it, resulting in forwarding
+      failures to non-supporting MTAs.  A downconvert in such cases will be
+      a no-op on the addresses, merely dropping the use of SMTPUTF8 by the
+      transport.  The change does mean that addresses needing conversion will
+      be converted when previously a delivery failure would occur.
