  Changes between 0.9.7 and 0.9.8  [xx XXX 2002]
 
+  *) Change internals of the EC library so that the functions

+          EC_GROUP_get_generator()
+          EC_GROUP_get_order()
+          EC_GROUP_get_cofactor()
+     are implemented directly in crypto/ec/ec_lib.c and not dispatched
+     to methods, which would lead to unnecessary code duplication when
+     adding different types of curves.
+     [Nils Larsch with input by Bodo Moeller]

   *) Implement compute_wNAF (crypto/ec/ec_mult.c) without BIGNUM
      arithmetic, and such that modified wNAFs are generated
      (which avoid length expansion in many cases).

+  *) Check the values of dna and dnb in bn_mul_recursive before calling
+     bn_mul_comba (a non zero value means the a or b arrays do not contain
+     n2 elements) and fallback to bn_mul_normal if either is not zero.

   *) Fix escaping of non-ASCII characters when using the -subj option
      of the "openssl req" command line tool. (Robert Joop <joop@fokus.gmd.de>)
