+JH/06 Check for bad chars in rDNS for sender_host_name. The OpenBSD (at least)
+ dn_expand() is happy to pass them through.
+
+JH/07 OpenSSL Fix auto-reload of changed server OCSP proof. Previously, if
+ the file with the proof had an unchanged name, the new proof(s) were
+ loaded on top of the old ones (and nover used; the old ones were stapled).
+
+JH/08 Bug 2915: Fix use-after-free for $regex<n> variables. Previously when
+ more than one message arrived in a single connection a reference from
+ the earlier message could be re-used. Often a sigsegv resulted.
+ These variables were introduced in Exim 4.87.
+ Debug help from Graeme Fowler.
+
+JH/09 Fix ${filter } for conditions that modify $value. Previously the
+ modified version would be used in construction the result, and a memory
+ error would occur.
+
+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.
