+  *) Add 'asn1_flag' and 'asn1_form' member to EC_GROUP with access
+     functions
+          EC_GROUP_set_asn1_flag()
+          EC_GROUP_get_asn1_flag()
+          EC_GROUP_set_point_conversion_form()
+          EC_GROUP_get_point_conversion_form()
+     These control ASN1 encoding details:
+     - Curve are encoded explicitly unless asn1_flag has been set to
+       OPENSSL_EC_NAMED_CURVE.
+     - Points are encoded in compressed form by default; options for
+       asn1_for are as for point2oct, namely
+          POINT_CONVERSION_COMPRESSED
+          POINT_CONVERSION_UNCOMPRESSED
+          POINT_CONVERSION_HYBRID

+  *) Add 'field_type' member to EC_METHOD, which holds the NID
+     of the appropriate field type OID.  The new function
+     EC_METHOD_get_field_type() returns this value.

   *) Remove most calls to EVP_CIPHER_CTX_cleanup() in evp_enc.c, this 
      allows existing EVP_CIPHER_CTX structures to be reused after
