+JH/04 Bug 2903: avoid exit on an attempt to rewrite a malformed address.

+JH/05 Follow symlinks for placing a watch on TLS creds files.  This means

+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.
