 Changes between 0.9.5a and 0.9.6  [xx XXX 2000]

  *) The obj_dat.pl script was messing up the sorting of object
     names. The reason was that it compared the quoted version
     of strings as a result "OCSP" > "OCSP Signing" because
     " > SPACE. Changed script to store unquoted versions of
     names and add quotes on output. It was also omitting some
     names from the lookup table if they were given a default
     value (that is if SN is missing it is given the same
     value as LN and vice versa), these are now added on the
     grounds that if an object has a name we should be able to
     look it up. Finally added warning output when duplicate
     short or long names are found.
     [Steve Henson]

  *) Changes needed for Tandem NSK.
     [Scott Uroff scott@xypro.com]

  *) Fix SSL 2.0 rollback checking: Due to an off-by-one error in
     RSA_padding_check_SSLv23(), special padding was never detected
     and thus the SSL 3.0/TLS 1.0 countermeasure against protocol
     version rollback attacks was not effective.

     In s23_clnt.c, don't use special rollback-attack detection padding
     (RSA_SSLV23_PADDING) if SSL 2.0 is the only protocol enabled in the
     client; similarly, in s23_srvr.c, don't do the rollback check if
     SSL 2.0 is the only protocol enabled in the server.
     [Bodo Moeller]

  *) Make it possible to get hexdumps of unprintable data with 'openssl
     asn1parse'.  By implication, the functions ASN1_parse_dump() and
     BIO_dump_indent() are added.
     [Richard Levitte]

  *) New functions ASN1_STRING_print_ex() and X509_NAME_print_ex()
     these print out strings and name structures based on various
     flags including RFC2253 support and proper handling of
     multibyte characters. Added options to the 'x509' utility 
     to allow the various flags to be set.
     [Steve Henson]

  *) Various fixes to use ASN1_TIME instead of ASN1_UTCTIME.
     Also change the functions X509_cmp_current_time() and
     X509_gmtime_adj() work with an ASN1_TIME structure,
     this will enable certificates using GeneralizedTime in validity
     dates to be checked.
     [Steve Henson]

  *) Make the NEG_PUBKEY_BUG code (which tolerates invalid
     negative public key encodings) on by default,
     NO_NEG_PUBKEY_BUG can be set to disable it.
     [Steve Henson]

  *) New function c2i_ASN1_OBJECT() which acts on ASN1_OBJECT
     content octets. An i2c_ASN1_OBJECT is unnecessary because
     the encoding can be trivially obtained from the structure.
     [Steve Henson]

  *) crypto/err.c locking bugfix: Use write locks (CRYPTO_w_[un]lock),
     not read locks (CRYPTO_r_[un]lock).
     [Bodo Moeller]

  *) A first attempt at creating official support for shared
     libraries through configuration.  I've kept it so the
     default is static libraries only, and the OpenSSL programs
     are always statically linked for now, but there are
     preparations for dynamic linking in place.
     This has been tested on Linux and True64.
     [Richard Levitte]

  *) Randomness polling function for Win9x, as described in:
     Peter Gutmann, Software Generation of Practically Strong
     Random Numbers.
