+JH/04 Bug 2903: avoid exit on an attempt to rewrite a malformed address.
+      Make the rewrite never match and keep the logging.  Trust the
+      admin to be using verify=header-syntax (to actually reject the message).
+
+JH/05 Follow symlinks for placing a watch on TLS creds files.  This means
+      (under Linux) we watch the dir containing the final file; previously
+      it would be the dir with the first symlink.  We still do not monitor
+      the entire path.
+
+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.
