  *) config has been changed so that by default OPENSSL_NO_DEPRECATED is used.
     Access to deprecated functions can be re-enabled by running config with
     "enable-deprecated". In addition applications wishing to use deprecated
     functions must define OPENSSL_USE_DEPRECATED. Note that this new behaviour
     will, by default, disable some transitive includes that previously existed
     in the header files (e.g. ec.h will no longer, by default, include bn.h)

  *) Added support for OCB mode. OpenSSL has been granted a patent license
     compatible with the OpenSSL license for use of OCB. Details are available
     at https://www.openssl.org/docs/misc/OCB-patent-grant-OpenSSL.pdf. Support
     for OCB can be removed by calling config with no-ocb.
     [Matt Caswell]
  *) SSLv2 support has been removed.  It still supports receiving a SSLv2
     compatible client hello.
     [Kurt Roeckx]

  *) Increased the minimal RSA keysize from 256 to 512 bits [Rich Salz],
     done while fixing the error code for the key-too-small case.
     [Annie Yousar <a.yousar@informatik.hu-berlin.de>]

  *) Remove various unsupported platforms:
	Sony NEWS4
	BEOS and BEOS_R5
	NeXT

	Sinix/ReliantUNIX RM400
	16-bit platforms such as WIN16
  *) Start cleaning up OPENSSL_NO_xxx #define's
	OPENSSL_NO_RIPEMD160, OPENSSL_NO_RIPEMD merged into OPENSSL_NO_RMD160
	OPENSSL_NO_FP_API merged into OPENSSL_NO_STDIO
	Use setbuf() and remove OPENSSL_NO_SETVBUF_IONBF
        Rename OPENSSL_SYSNAME_xxx to OPENSSL_SYS_xxx
        Remove MS_STATIC; it's a relic from platforms <32 bits.
     [Rich Salz]

  *) Start cleaning up dead code
        Remove all but one '#ifdef undef' which is to be looked at.

  *) Experimental support for a new, fast, unbiased prime candidate generator,
     bn_probable_prime_dh_coprime(). Not currently used by any prime generator.
     [Felix Laurie von Massenbach <felix@erbridge.co.uk>]

  *) New output format NSS in the sess_id command line tool. This allows
     exporting the session id and the master key in NSS keylog format.

  *) Harmonize version and its documentation. -f flag is used to display
     compilation flags.

  *) Fix eckey_priv_encode so it immediately returns an error upon a failure
     in i2d_ECPrivateKey.

  *) Fix some double frees. These are not thought to be exploitable.
     [mancha <mancha1@zoho.com>]

  *) A missing bounds check in the handling of the TLS heartbeat extension
     can be used to reveal up to 64k of memory to a connected client or
     server.

     Thanks for Neel Mehta of Google Security for discovering this bug and to
     Adam Langley <agl@chromium.org> and Bodo Moeller <bmoeller@acm.org> for
     preparing the fix (CVE-2014-0160)
     [Adam Langley, Bodo Moeller]

  *) Fix for the attack described in the paper "Recovering OpenSSL
     ECDSA Nonces Using the FLUSH+RELOAD Cache Side-channel Attack"
     by Yuval Yarom and Naomi Benger. Details can be obtained from:
     http://eprint.iacr.org/2014/140

     Thanks to Yuval Yarom and Naomi Benger for discovering this
     flaw and to Yuval Yarom for supplying a fix (CVE-2014-0076)
     [Yuval Yarom and Naomi Benger]

  *) Use algorithm specific chains in SSL_CTX_use_certificate_chain_file():
     this fixes a limitation in previous versions of OpenSSL.
  *) Experimental encrypt-then-mac support.
    
     Experimental support for encrypt then mac from
     draft-gutmann-tls-encrypt-then-mac-02.txt
     To enable it set the appropriate extension number (0x42 for the test
     server) using e.g. -DTLSEXT_TYPE_encrypt_then_mac=0x42
     For non-compliant peers (i.e. just about everything) this should have no
     effect.

     WARNING: EXPERIMENTAL, SUBJECT TO CHANGE.
  *) Add EVP support for key wrapping algorithms, to avoid problems with
     existing code the flag EVP_CIPHER_CTX_WRAP_ALLOW has to be set in
     the EVP_CIPHER_CTX or an error is returned. Add AES and DES3 wrap
     algorithms and include tests cases.

  *) Extend CMS code to support RSA-PSS signatures and RSA-OAEP for
     enveloped data.
     [Steve Henson]

  *) Extended RSA OAEP support via EVP_PKEY API. Options to specify digest,
     MGF1 digest and OAEP label.
     [Steve Henson]

  *) Make openssl verify return errors.
     [Chris Palmer <palmer@google.com> and Ben Laurie]

  *) New function ASN1_TIME_diff to calculate the difference between two
     ASN1_TIME structures or one structure and the current time.
     [Steve Henson]

  *) Update fips_test_suite to support multiple command line options. New
     test to induce all self test errors in sequence and check expected
     failures.
     [Steve Henson]

  *) Add FIPS_{rsa,dsa,ecdsa}_{sign,verify} functions which digest and
     sign or verify all in one operation.
     [Steve Henson]

  *) Add fips_algvs: a multicall fips utility incorporating all the algorithm
     test programs and fips_test_suite. Includes functionality to parse
     the minimal script output of fipsalgest.pl directly.
  *) Add authorisation parameter to FIPS_module_mode_set().
     [Steve Henson]

  *) Add FIPS selftest for ECDH algorithm using P-224 and B-233 curves.
     [Steve Henson]

  *) Use separate DRBG fields for internal and external flags. New function
     FIPS_drbg_health_check() to perform on demand health checking. Add
     generation tests to fips_test_suite with reduced health check interval to 
     demonstrate periodic health checking. Add "nodh" option to
     fips_test_suite to skip very slow DH test.
     [Steve Henson]

  *) New function FIPS_get_cipherbynid() to lookup FIPS supported ciphers
     based on NID.
     [Steve Henson]

  *) More extensive health check for DRBG checking many more failure modes.
     New function FIPS_selftest_drbg_all() to handle every possible DRBG
     combination: call this in fips_test_suite.
     [Steve Henson]

  *) Add support for Dual EC DRBG from SP800-90. Update DRBG algorithm test
     and POST to handle Dual EC cases.
     [Steve Henson]

  *) Add support for canonical generation of DSA parameter 'g'. See 
     FIPS 186-3 A.2.3.

  *) Add support for HMAC DRBG from SP800-90. Update DRBG algorithm test and
     POST to handle HMAC cases.
     [Steve Henson]

  *) Add functions FIPS_module_version() and FIPS_module_version_text()
     to return numerical and string versions of the FIPS module number.
  *) Rename FIPS_mode_set and FIPS_mode to FIPS_module_mode_set and
     FIPS_module_mode. FIPS_mode and FIPS_mode_set will be implemented
     outside the validated module in the FIPS capable OpenSSL.
     [Steve Henson]

  *) Minor change to DRBG entropy callback semantics. In some cases
     there is no multiple of the block length between min_len and
     max_len. Allow the callback to return more than max_len bytes
     of entropy but discard any extra: it is the callback's responsibility
     to ensure that the extra data discarded does not impact the
     requested amount of entropy.
     [Steve Henson]

  *) Add PRNG security strength checks to RSA, DSA and ECDSA using 
     information in FIPS186-3, SP800-57 and SP800-131A.
     [Steve Henson]

  *) CCM support via EVP. Interface is very similar to GCM case except we
