  *) BeOS support.
     [Oliver Tappe <zooey@hirschkaefer.de>]

  *) New make target "install_html_docs" installs HTML renditions of the
     manual pages.
     [Oliver Tappe <zooey@hirschkaefer.de>]

  *) New utility "genpkey" this is analagous to "genrsa" etc except it can
     generate keys for any algorithm. Extend and update EVP_PKEY_METHOD to
     support key and parameter generation and add initial key generation
     functionality for RSA.
     [Steve Henson]

  *) Add functions for main EVP_PKEY_method operations. The undocumented
     functions EVP_PKEY_{encrypt,decrypt} have been renamed to
     EVP_PKEY_{encrypt,decrypt}_old. 
     [Steve Henson]

  *) Initial definitions for EVP_PKEY_METHOD. This will be a high level public
     key API, doesn't do much yet.
     [Steve Henson]

  *) New function EVP_PKEY_asn1_get0_info() to retrieve information about
     public key algorithms. New option to openssl utility:
     "list-public-key-algorithms" to print out info.
     [Steve Henson]

  *) Implement the Supported Elliptic Curves Extension for
     ECC ciphersuites from draft-ietf-tls-ecc-12.txt.
     [Douglas Stebila]

  *) Don't free up OIDs in OBJ_cleanup() if they are in use by EVP_MD or
     EVP_CIPHER structures to avoid later problems in EVP_cleanup().
     [Steve Henson]

  *) New utilities pkey and pkeyparam. These are similar to algorithm specific
     utilities such as rsa, dsa, dsaparam etc except they process any key
  *) Transfer public key printing routines to EVP_PKEY_ASN1_METHOD. New 
     functions EVP_PKEY_print_public(), EVP_PKEY_print_private(),
     EVP_PKEY_print_param() to print public key data from an EVP_PKEY
     structure.
     [Steve Henson]

  *) Initial support for pluggable public key ASN1.
     De-spaghettify the public key ASN1 handling. Move public and private
     key ASN1 handling to a new EVP_PKEY_ASN1_METHOD structure. Relocate
     algorithm specific handling to a single module within the relevant
     algorithm directory. Add functions to allow (near) opaque processing
     of public and private key structures.
     [Steve Henson]

  *) Implement the Supported Point Formats Extension for
     ECC ciphersuites from draft-ietf-tls-ecc-12.txt.
     [Douglas Stebila]

  *) Add initial support for RFC 4279 PSK TLS ciphersuites. Add members
     for the psk identity [hint] and the psk callback functions to the
     SSL_SESSION, SSL and SSL_CTX structure.
     
     New ciphersuites:
         PSK-RC4-SHA, PSK-3DES-EDE-CBC-SHA, PSK-AES128-CBC-SHA,
         PSK-AES256-CBC-SHA
 
     New functions:
         SSL_CTX_use_psk_identity_hint
         SSL_get_psk_identity_hint
         SSL_get_psk_identity
         SSL_use_psk_identity_hint

     [Mika Kousa and Pasi Eronen of Nokia Corporation]

  *) Add RFC 3161 compliant time stamp request creation, response generation
     and response verification functionality.
     [Zoltán Glózik <zglozik@opentsa.org>, The OpenTSA Project]

  *) Add initial support for TLS extensions, specifically for the server_name
     extension so far.  The SSL_SESSION, SSL_CTX, and SSL data structures now
     have new members for a host name.  The SSL data structure has an
     additional member SSL_CTX *initial_ctx so that new sessions can be
     stored in that context to allow for session resumption, even after the
     SSL has been switched to a new SSL_CTX in reaction to a client's
     server_name extension.

     New functions (subject to change):

         SSL_get_servername()
         SSL_get_servername_type()
         SSL_set_SSL_CTX()

     New CTRL codes and macros (subject to change):

         SSL_CTRL_SET_TLSEXT_SERVERNAME_CB
                                 - SSL_CTX_set_tlsext_servername_callback()
         SSL_CTRL_SET_TLSEXT_SERVERNAME_ARG
                                      - SSL_CTX_set_tlsext_servername_arg()
         SSL_CTRL_SET_TLSEXT_HOSTNAME           - SSL_set_tlsext_hostname()

     openssl s_client has a new '-servername ...' option.

     openssl s_server has new options '-servername_host ...', '-cert2 ...',
     '-key2 ...', '-servername_fatal' (subject to change).  This allows
     testing the HostName extension for a specific single host name ('-cert'
     and '-key' remain fallbacks for handshakes without HostName
     negotiation).  If the unrecogninzed_name alert has to be sent, this by
     default is a warning; it becomes fatal with the '-servername_fatal'
     option.

  *) Whirlpool hash implementation is added.
     [Andy Polyakov]

  *) 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.
  *) 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.
