 Changes between 0.9.8a and 0.9.9  [xx XXX xxxx]



  *) 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.
