  OpenSSL CHANGES
  _______________
 
- Changes between 0.9.7e and 0.9.8  [xx XXX xxxx]
+ Changes between 0.9.8a and 0.9.9  [xx XXX xxxx]
+
+  *) BIGNUM code on 64-bit SPARCv9 targets is switched from bn(64,64) to
+     bn(64,32). Because of instruction set limitations it doesn't have
+     any negative impact on performance. This was done mostly in order
+     to make it possible to share assembler modules, such as bn_mul_mont
+     implementations, between 32- and 64-bit builds without hassle.
+     [Andy Polyakov]
+
+  *) Disable rogue ciphersuites:
+
+      - SSLv2 0x08 0x00 0x80 ("RC4-64-MD5")
+      - SSLv3/TLSv1 0x00 0x61 ("EXP1024-RC2-CBC-MD5")
+      - SSLv3/TLSv1 0x00 0x60 ("EXP1024-RC4-MD5")
+
+     The latter two were purportedly from
+     draft-ietf-tls-56-bit-ciphersuites-0[01].txt, but do not really
+     appear there.
+
+     Other ciphersuites from draft-ietf-tls-56-bit-ciphersuites-01.txt
+     remain enabled for now, but are just as unofficial, and the ID
+     has long expired; these will probably disappear soon.
+     [Bodo Moeller]
+
+  *) Move code previously exiled into file crypto/ec/ec2_smpt.c
+     to ec2_smpl.c, and no longer require the OPENSSL_EC_BIN_PT_COMP
+     macro.
+     [Bodo Moeller]
+
+  *) New candidate for BIGNUM assembler implementation, bn_mul_mont,
+     dedicated Montgomery multiplication procedure, is introduced.
+     BN_MONT_CTX is modified to allow bn_mul_mont to reach for higher
+     "64-bit" performance on certain 32-bit targets.
+     [Andy Polyakov]
+
+  *) New option SSL_OP_NO_COMP to disable use of compression selectively
+     in SSL structures. New SSL ctrl to set maximum send fragment size. 
+     Save memory by seeting the I/O buffer sizes dynamically instead of
+     using the maximum available value.
+     [Steve Henson]
+
+  *) New option -V for 'openssl ciphers'. This prints the ciphersuite code
+     in addition to the text details.
+     [Bodo Moeller]
+
+  *) Very, very preliminary EXPERIMENTAL support for printing of general
+     ASN1 structures. This currently produces rather ugly output and doesn't
+     handle several customised structures at all.
+     [Steve Henson]
+
+  *) Integrated support for PVK file format and some related formats such
+     as MS PUBLICKEYBLOB and PRIVATEKEYBLOB. Command line switches to support
+     these in the 'rsa' and 'dsa' utilities.
+     [Steve Henson]
+
+  *) Support for PKCS#1 RSAPublicKey format on rsa utility command line.
+     [Steve Henson]
+
+  *) Remove the ancient ASN1_METHOD code. This was only ever used in one
+     place for the (very old) "NETSCAPE" format certificates which are now
+     handled using new ASN1 code equivalents.
+     [Steve Henson]
+
+  *) Let the TLSv1_method() etc. functions return a 'const' SSL_METHOD
+     pointer and make the SSL_METHOD parameter in SSL_CTX_new,
+     SSL_CTX_set_ssl_version and SSL_set_ssl_method 'const'.
+     [Nils Larsch]
+
+  *) Modify CRL distribution points extension code to print out previously
+     unsupported fields. Enhance extension setting code to allow setting of
+     all fields.
+     [Steve Henson]
+
+  *) Add print and set support for Issuing Distribution Point CRL extension.
+     [Steve Henson]
+
+ Changes between 0.9.8a and 0.9.8b  [XX xxx XXXX]
+
+  *) Update support for ECC-based TLS ciphersuites according to
+     draft-ietf-tls-ecc-12.txt with proposed changes.
+     [Douglas Stebila]
+
+  *) New functions EVP_CIPHER_CTX_new() and EVP_CIPHER_CTX_free() to support
+     opaque EVP_CIPHER_CTX handling.
+     [Steve Henson]
+
+  *) Fixes and enhancements to zlib compression code. We now only use
+     "zlib1.dll" and use the default __cdecl calling convention on Win32
+     to conform with the standards mentioned here:
+           http://www.zlib.net/DLL_FAQ.txt
+     Static zlib linking now works on Windows and the new --with-zlib-include
+     --with-zlib-lib options to Configure can be used to supply the location
+     of the headers and library. Gracefully handle case where zlib library
+     can't be loaded.
+     [Steve Henson]
+
+  *) Several fixes and enhancements to the OID generation code. The old code
+     sometimes allowed invalid OIDs (1.X for X >= 40 for example), couldn't
+     handle numbers larger than ULONG_MAX, truncated printing and had a
+     non standard OBJ_obj2txt() behaviour.
+     [Steve Henson]
+
+  *) Add support for building of engines under engine/ as shared libraries
+     under VC++ build system.
+     [Steve Henson]
+
+  *) Corrected the numerous bugs in the Win32 path splitter in DSO.
+     Hopefully, we will not see any false combination of paths any more.
+     [Richard Levitte]
+
+ Changes between 0.9.8 and 0.9.8a  [11 Oct 2005]
+
+  *) Remove the functionality of SSL_OP_MSIE_SSLV2_RSA_PADDING
+     (part of SSL_OP_ALL).  This option used to disable the
+     countermeasure against man-in-the-middle protocol-version
+     rollback in the SSL 2.0 server implementation, which is a bad
+     idea.  (CVE-2005-2969)
+
+     [Bodo Moeller; problem pointed out by Yutaka Oiwa (Research Center
+     for Information Security, National Institute of Advanced Industrial
+     Science and Technology [AIST], Japan)]
+
+  *) Add two function to clear and return the verify parameter flags.
+     [Steve Henson]
+
+  *) Keep cipherlists sorted in the source instead of sorting them at
+     runtime, thus removing the need for a lock.
+     [Nils Larsch]
+
+  *) Avoid some small subgroup attacks in Diffie-Hellman.
+     [Nick Mathewson and Ben Laurie]
+
+  *) Add functions for well-known primes.
+     [Nick Mathewson]
+
+  *) Extended Windows CE support.
+     [Satoshi Nakamura and Andy Polyakov]
+
+  *) Initialize SSL_METHOD structures at compile time instead of during
+     runtime, thus removing the need for a lock.
+     [Steve Henson]
+
+  *) Make PKCS7_decrypt() work even if no certificate is supplied by
+     attempting to decrypt each encrypted key in turn. Add support to
+     smime utility.
+     [Steve Henson]
+
+ Changes between 0.9.7h and 0.9.8  [05 Jul 2005]
+
+  *) Add libcrypto.pc and libssl.pc for those who feel they need them.
+     [Richard Levitte]
+
+  *) Change CA.sh and CA.pl so they don't bundle the CSR and the private
+     key into the same file any more.
+     [Richard Levitte]
+
+  *) Add initial support for Win64, both IA64 and AMD64/x64 flavors.
+     [Andy Polyakov]
+
+  *) Add -utf8 command line and config file option to 'ca'.
+     [Stefan <stf@udoma.org]
+
+  *) Removed the macro des_crypt(), as it seems to conflict with some
+     libraries.  Use DES_crypt().
+     [Richard Levitte]
+
+  *) Correct naming of the 'chil' and '4758cca' ENGINEs. This
+     involves renaming the source and generated shared-libs for
+     both. The engines will accept the corrected or legacy ids
+     ('ncipher' and '4758_cca' respectively) when binding. NB,
+     this only applies when building 'shared'.
+     [Corinna Vinschen <vinschen@redhat.com> and Geoff Thorpe]
+
+  *) Add attribute functions to EVP_PKEY structure. Modify
+     PKCS12_create() to recognize a CSP name attribute and
+     use it. Make -CSP option work again in pkcs12 utility.
+     [Steve Henson]
+
+  *) Add new functionality to the bn blinding code:
+     - automatic re-creation of the BN_BLINDING parameters after
+       a fixed number of uses (currently 32)
+     - add new function for parameter creation
+     - introduce flags to control the update behaviour of the
+       BN_BLINDING parameters
+     - hide BN_BLINDING structure
+     Add a second BN_BLINDING slot to the RSA structure to improve
+     performance when a single RSA object is shared among several
+     threads.
+     [Nils Larsch]
+
+  *) Add support for DTLS.
+     [Nagendra Modadugu <nagendra@cs.stanford.edu> and Ben Laurie]
+
+  *) Add support for DER encoded private keys (SSL_FILETYPE_ASN1)
+     to SSL_CTX_use_PrivateKey_file() and SSL_use_PrivateKey_file()
+     [Walter Goulet]
+
+  *) Remove buggy and incompletet DH cert support from
+     ssl/ssl_rsa.c and ssl/s3_both.c
+     [Nils Larsch]
+
+  *) Use SHA-1 instead of MD5 as the default digest algorithm for
+     the apps/openssl applications.
+     [Nils Larsch]
+
+  *) Compile clean with "-Wall -Wmissing-prototypes
+     -Wstrict-prototypes -Wmissing-declarations -Werror". Currently
+     DEBUG_SAFESTACK must also be set.
+     [Ben Laurie]
 
   *) Change ./Configure so that certain algorithms can be disabled by default.
      The new counterpiece to "no-xxx" is "enable-xxx".

- Changes between 0.9.7f and 0.9.7g  [XX xxx xxxx]
+ Changes between 0.9.7h and 0.9.7i  [14 Oct 2005]
+

+
+  *) Minimal support for X9.31 signatures and PSS padding modes. This is
+     mainly for FIPS compliance and not fully integrated at this stage.
+     [Steve Henson]
+
+  *) For DSA signing, unless DSA_FLAG_NO_EXP_CONSTTIME is set, perform
+     the exponentiation using a fixed-length exponent.  (Otherwise,
+     the information leaked through timing could expose the secret key
+     after many signatures; cf. Bleichenbacher's attack on DSA with
+     biased k.)
+     [Bodo Moeller]
+
+  *) Make a new fixed-window mod_exp implementation the default for
+     RSA, DSA, and DH private-key operations so that the sequence of
+     squares and multiplies and the memory access pattern are
+     independent of the particular secret key.  This will mitigate
