  _______________
 
  Changes between 1.0.2 and 1.1.0  [xx XXX xxxx]
+
+  *) State machine rewrite. The state machine code has been significantly
+     refactored in order to remove much duplication of code and solve issues
+     with the old code (see ssl/statem/README for further details). This change
+     does have some associated API changes. Notably SSL_get_state/SSL_state now
+     returns an "enum HANDSHAKE_STATE" instead of an int. The previous handshake
+     states defined in ssl.h and ssl3.h have been redefined to be the nearest
+     equivalent HANDSHAKE_STATE value. Not all states have an equivalent value,
+     (e.g. SSL_ST_CW_FLUSH). New application code should not use the old
+     handshake state values, but should instead use HANDSHAKE_STATE.
+     [Matt Caswell]
+
+  *) The demo files in crypto/threads were moved to demo/threads.
+     [Rich Salz]
+
+  *) Removed obsolete engines: 4758cca, aep, atalla, cswift, nuron and sureware.
+     [Matt Caswell]
+
+  *) New ASN.1 embed macro.
+
+     New ASN.1 macro ASN1_EMBED. This is the same as ASN1_SIMPLE except the
+     structure is not allocated: it is part of the parent. That is instead of
+
+     FOO *x;
+
+     it must be:
+
+     FOO x;
+
+     This reduces memory fragmentation and make it impossible to accidentally
+     set a mandatory field to NULL.
+
+     This currently only works for some fields specifically a SEQUENCE, CHOICE,
+     or ASN1_STRING type which is part of a parent SEQUENCE. Since it is
+     equivalent to ASN1_SIMPLE it cannot be tagged, OPTIONAL, SET OF or
+     SEQUENCE OF.
+     [Steve Henson]
+
+  *) Remove EVP_CHECK_DES_KEY, a compile-time option that never compiled.
+     [Emilia Käsper]
+
+  *) Removed DES and RC4 ciphersuites from DEFAULT. Also removed RC2 although
+     in 1.0.2 EXPORT was already removed and the only RC2 ciphersuite is also
+     an EXPORT one. COMPLEMENTOFDEFAULT has been updated accordingly to add
+     DES and RC4 ciphersuites.
+     [Matt Caswell]
+
+  *) Rewrite EVP_DecodeUpdate (base64 decoding) to fix several bugs.
+     This changes the decoding behaviour for some invalid messages,
+     though the change is mostly in the more lenient direction, and
+     legacy behaviour is preserved as much as possible.
+     [Emilia Käsper]
+  *) Fix no-stdio build.
+    [ David Woodhouse <David.Woodhouse@intel.com> and also
+      Ivan Nestlerode <ivan.nestlerode@sonos.com> ]
+
+  *) New testing framework
+     The testing framework has been largely rewritten and is now using
+     perl and the perl modules Test::Harness and an extended variant of
+     Test::More called OpenSSL::Test to do its work.  All test scripts in
+     test/ have been rewritten into test recipes, and all direct calls to
+     executables in test/Makefile have become individual recipes using the
+     simplified testing OpenSSL::Test::Simple.
+
+     For documentation on our testing modules, do:
+
+        perldoc test/testlib/OpenSSL/Test/Simple.pm
+        perldoc test/testlib/OpenSSL/Test.pm

+     return an error
+     [Rich Salz and Ismo Puustinen <ismo.puustinen@intel.com>]
+
+  *) Rewrite PSK to support ECDHE_PSK, DHE_PSK and RSA_PSK. Add ciphersuites
+     from RFC4279, RFC4785, RFC5487, RFC5489.
+
+     Thanks to Christian J. Dietrich and Giuseppe D'Angelo for the
+     original RSA_PSK patch.
+     [Steve Henson]
+
+  *) Dropped support for the SSL3_FLAGS_DELAY_CLIENT_FINISHED flag. This SSLeay
+     era flag was never set throughout the codebase (only read). Also removed
+     SSL3_FLAGS_POP_BUFFER which was only used if
+     SSL3_FLAGS_DELAY_CLIENT_FINISHED was also set.
+     [Matt Caswell]
+
   *) Changed the default name options in the "ca", "crl", "req" and "x509"
      to be "oneline" instead of "compat".
