CHANGES

  Changes between 0.9.8a and 0.9.9  [xx XXX xxxx]
 
+  *) New utility 'pkey'. This is similar to algorithm specific utilities
+     such as 'rsa', 'dsa' etc except it processes any key type.
+     [Steve Henson]
+
   *) 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
