  Changes between 0.9.7h and 0.9.8  [xx XXX xxxx]
 
+  *) 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)
