+   or later and do want PKCS11 modules to be autoloaded, then set this option.

+ * A per-transport wait-<name> database is no longer updated if the transport
+   sets "connection_max_messages" to 1, as it can not be used and causes
+   unnecessary serialisation and load.  External tools tracking the state of
+   Exim by the hints databases may need modification to take this into account.

+ * For OpenSSL, SSLv2 is now disabled by default.  (GnuTLS does not support
