 Version 4.78
+------------
 
- 1. New expansion variable $tls_bits.
+ 1. New authenticator driver, "gsasl".  Server-only (at present).
+    This is a SASL interface, licensed under GPL, which can be found at
+    http://www.gnu.org/software/gsasl/.
+    This system does not provide sources of data for authentication, so
+    careful use needs to be made of the conditions in Exim.
+
+ 2. New authenticator driver, "heimdal_gssapi".  Server-only.
+    A replacement for using cyrus_sasl with Heimdal, now that $KRB5_KTNAME
+    is no longer honoured for setuid programs by Heimdal.  Use the
+    "server_keytab" option to point to the keytab.
+
+ 3. The "pkg-config" system can now be used when building Exim to reference
+    cflags and library information for lookups and authenticators, rather
+    than having to update "CFLAGS", "AUTH_LIBS", "LOOKUP_INCLUDE" and
+    "LOOKUP_LIBS" directly.  Similarly for handling the TLS library support
+    without adjusting "TLS_INCLUDE" and "TLS_LIBS".
+
+ 4. New expansion variable $tls_bits.
+
+ 5. New lookup type, "dbmjz".  Key is an Exim list, the elements of which will
+    be joined together with ASCII NUL characters to construct the key to pass
+    into the DBM library.  Can be used with gsasl to access sasldb2 files as
+    used by Cyrus SASL.
+
+ 6. OpenSSL now supports TLS1.1 and TLS1.2 with OpenSSL 1.0.1.
+
+    Avoid release 1.0.1a if you can.  Note that the default value of
+    "openssl_options" is no longer "+dont_insert_empty_fragments", as that
+    increased susceptibility to attack.  This may still have interoperability
+    implications for very old clients (see version 4.31 change 37) but
+    administrators can choose to make the trade-off themselves and restore
+    compatibility at the cost of session security.
+
+ 7. Use of the new expansion variable $tls_sni in the main configuration option
+    tls_certificate will cause Exim to re-expand the option, if the client
+    sends the TLS Server Name Indication extension, to permit choosing a
+    different certificate; tls_privatekey will also be re-expanded.  You must
+    still set these options to expand to valid files when $tls_sni is not set.
+
+    The SMTP Transport has gained the option tls_sni, which will set a hostname
+    for outbound TLS sessions, and set $tls_sni too.
+
+    A new log_selector, +tls_sni, has been added, to log received SNI values
+    for Exim as a server.
+
+    Currently OpenSSL only.
+
+ 8. The existing "accept_8bitmime" option now defaults to true.  This means
+    that Exim is deliberately not strictly RFC compliant.  We're following
+    Dan Bernstein's advice in http://cr.yp.to/smtp/8bitmime.html by default.
+    Those who disagree, or know that they are talking to mail servers that,
+    even today, are not 8-bit clean, need to turn off this option.
+
+ 9. Exim can now be started with -bw (with an optional timeout, given as
+    -bw<timespec>).  With this, stdin at startup is a socket that is
+    already listening for connections.  This has a more modern name of
+    "socket activation", but forcing the activated socket to fd 0.  We're
+    interested in adding more support for modern variants.
