 OpenSSL CHANGES
 Changes between 0.9.8a and 0.9.9  [xx XXX xxxx]
  *) 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.
  *) 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.
  *) Add print and set support for Issuing Distribution Point CRL extension.

 Changes between 0.9.8a and 0.9.8b  [XX xxx XXXX]

  *) Add support for building of engines under engine/ as shared libraries
     under VC++ build system.

  *) 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.

  *) 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.

  *) 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.

  *) 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".

     The patented RC5 and MDC2 algorithms will now be disabled unless
     "enable-rc5" and "enable-mdc2", respectively, are specified.

     (IDEA remains enabled despite being patented.  This is because IDEA
     is frequently required for interoperability, and there is no license
     fee for non-commercial use.  As before, "no-idea" can be used to
     avoid this algorithm.)

  *) Add processing of proxy certificates (see RFC 3820).  This work was
     sponsored by KTH (The Royal Institute of Technology in Stockholm) and
     EGEE (Enabling Grids for E-science in Europe).
     [Richard Levitte]

  *) RC4 performance overhaul on modern architectures/implementations, such
     as Intel P4, IA-64 and AMD64.
     [Andy Polyakov]

  *) New utility extract-section.pl. This can be used specify an alternative
     section number in a pod file instead of having to treat each file as
     a separate case in Makefile. This can be done by adding two lines to the
     pod file:

     =for comment openssl_section:XXX

     The blank line is mandatory.

  *) New arguments -certform, -keyform and -pass for s_client and s_server
     to allow alternative format key and certificate files and passphrase
     sources.
