Changes between 0.9.7c and 0.9.8 [xx XXX xxxx]
+ *) Preliminary support for certificate policy evaluation and checking. This
+ is initially intended to pass the tests outlined in "Conformance Testing
+ of Relying Party Client Certificate Path Processing Logic" v1.07.
+ [Steve Henson]
+
*) bn_dup_expand() has been deprecated, it was introduced in 0.9.7 and
remained unused and not that useful. A variety of other little bignum
tweaks and fixes have also been made continuing on from the audit (see
