Changes between 0.9.4 and 0.9.5 [xx XXX 1999]
+ *) New function PKCS12_newpass() which changes the password of a
+ PKCS12 structure.
+ [Steve Henson]
+
*) Modify X509_TRUST and X509_PURPOSE so it also uses a static and
dynamic mix. In both cases the ids can be used as an index into the
table. Also modified the X509_TRUST_add() and X509_PURPOSE_add()
