@@ -43,6 +43,61 @@ JH/09 Fix ${filter } for conditions that modify $value.  Previously the
 JH/10 GnuTLS: fix for (IOT?) clients offering no TLS extensions at all.
       Find and fix by Jasen Betts.
 
+JH/11 OpenSSL: fix for ancient clients needing TLS support for versions earlier
+      than TLSv1,2,  Previously, more-recent versions of OpenSSL were permitting
+      the systemwide configuration to override the Exim config.
+
+HS/01 Bug 2728: Introduce EDITME option "DMARC_API" to work around incompatible
+      API changes in libopendmarc.
+
+JH/12 Bug 2930: Fix daemon startup.  When started from any process apart from
+      pid 1, in the normal "background daemon" mode, having to drop process-
+      group leadership also lost track of needing to create listener sockets.
+
+JH/13 Bug 2929: Fix using $recipients after ${run...}.  A change made for 4.96
+      resulted in the variable appearing empty.  Find and fix by Ruben Jenster.
+
+JH/14 Bug 2933: Fix regex substring match variables for null matches. Since 4.96
+      a capture group which obtained no text (eg. "(abc)*" matching zero
+      occurrences) could cause a segfault if the corresponding $<n> was
+      expanded.
+
+JH/15 Fix argument parsing for ${run } expansion. Previously, when an argument
+      included a close-brace character (eg. it itself used an expansion) an
+      error occurred.
+
+JH/16 Move running the smtp connect ACL to before, for TLS-on-connect ports,
+      starting TLS.  Previously it was after, meaning that attackers on such
+      ports had to be screened using the host_reject_connection main config
+      option. The new sequence aligns better with the STARTTLS behaviour, and
+      permits defences against crypto-processing load attacks, even though it
+      is strictly an incompatible change.
+      Also, avoid sending any SMTP fail response for either the connect ACL
+      or host_reject_connection, for TLS-on-connect ports.
+
+JH/17 Permit the ACL "encrypted" condition to be used in a HELO/EHLO ACL,
+      Previously this was not permitted, but it makes reasonable sense.
+      While there, restore a restriction on using it from a connect ACL; given
+      the change JH/16 it could only return false (and before 4.91 was not
+      permitted).
+
+JH/18 Fix a fencepost error in logging.  Previously (since 4.92) when a log line
+      was exactly sized compared to the log buffer, a crash occurred with the
+      misleading message "bad memory reference; pool not found".
+      Found and traced by Jasen Betts.
+
+JH/19 Bug 2911: Fix a recursion in DNS lookups.  Previously, if the main option
+      dns_again_means_nonexist included an element causing a DNS lookup which
+      iteslf returned DNS_AGAIN, unbounded recursion occurred.  Possible results
+      included (though probably not limited to) a process crash from stack
+      memory limit, or from excessive open files.  Replace this with a paniclog
+      whine (as this is likely a configuration error), and returning
+      DNS_NOMATCH.
+
+JH/20 Bug 2954: (OpenSSL) Fix setting of explicit EC curve/group.  Previously
+      this always failed, probably leading to the usual downgrade to in-clear
+      connections.
