 13. ${lookup dnsdb{ }} supports now SPF record types. They are handled
     identically to TXT record lookups.
 
+14. New expansion variable $tod_epoch_l for higher-precision time.
+
+15. New global option tls_dh_max_bits, defaulting to current value of NSS
+    hard-coded limit of DH ephemeral bits, to fix interop problems caused by
+    GnuTLS 2.12 library recommending a bit count higher than NSS supports.
+
+16. tls_dhparam now used by both OpenSSL and GnuTLS, can be path or identifier.
+    Option can now be a path or an identifier for a standard prime.
+    If unset, we use the DH prime from section 2.2 of RFC 5114, "ike23".
+    Set to "historic" to get the old GnuTLS behaviour of auto-generated DH
+    primes.
