  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
