  Changes between 1.0.2 and 1.1.0  [xx XXX xxxx]
 
+  *) Added ASYNC support. Libcrypto now includes the async sub-library to enable
+     cryptographic operations to be performed asynchronously as long as an
+     asynchronous capable engine is used. See the ASYNC_start_job() man page for
+     further details. Libssl has also had this capability integrated with the
+     introduction of the new mode SSL_MODE_ASYNC and associated error
+     SSL_ERROR_WANT_ASYNC. See the SSL_CTX_set_mode() and SSL_get_error() man
+     pages. This work was developed in partnership with Intel Corp.
+     [Matt Caswell]
+
+  *) SSL_{CTX_}set_ecdh_auto() has been removed and ECDH is support is
+     always enabled now.  If you want to disable the support you should
+     exclude it using the list of supported ciphers.
+     [Kurt Roeckx]
+
+  *) SSL_{CTX}_set_tmp_ecdh() which can set 1 EC curve now internally calls
+     SSL_{CTX_}set1_curves() which can set a list.
+     [Kurt Roeckx]
+
+  *) Remove support for SSL_{CTX_}set_tmp_ecdh_callback().  You should set the
+     curve you want to support using SSL_{CTX_}set1_curves().
+     [Kurt Roeckx]
+
+  *) 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 the SSL_state() function
+     has been removed and replaced by SSL_get_state which now returns an
+     "OSSL_HANDSHAKE_STATE" instead of an int. SSL_set_state() has been removed
+     altogether. The previous handshake states defined in ssl.h and ssl3.h have
+     also been removed.
+     [Matt Caswell]
+
+  *) All instances of the string "ssleay" in the public API were replaced
+     with OpenSSL (case-matching; e.g., OPENSSL_VERSION for #define's)
+     Some error codes related to internal RSA_eay API's were renamed.
+     [Rich Salz]
+
+  *) 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.
