+10. ${eval } now uses 64-bit values on supporting platforms.  A new "G" suffix

+11. The GnuTLS support has been revamped; the three options gnutls_require_kx,
+    gnutls_require_mac & gnutls_require_protocols are no longer supported.
+    tls_require_ciphers is now parsed by gnutls_priority_init(3) as a priority
+    string, documentation for which is at:
+    http://www.gnu.org/software/gnutls/manual/html_node/Priority-Strings.html
+
+    SNI support has been added to Exim's GnuTLS integration too.
+
+    For sufficiently recent GnuTLS libraries, ${randint:..} will now use
+    gnutls_rnd(), asking for GNUTLS_RND_NONCE level randomness.
+
+12. With OpenSSL, if built with EXPERIMENTAL_OCSP, a new option tls_ocsp_file
+    is now available.  If the contents of the file are valid, then Exim will
+    send that back in response to a TLS status request; this is OCSP Stapling.
+    Exim will not maintain the contents of the file in any way: administrators
+    are responsible for ensuring that it is up-to-date.
+
+    See "experimental-spec.txt" for more details.

+    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".
