  Changes between 0.9.5 and 0.9.6  [XX XXX 2000]
 
+  *) In PEM_ASN1_write_bio and some other functions, use RAND_pseudo_bytes
+     instead of RAND_bytes for encryption IVs and salts.
+     [Bodo Moeller]
+
   *) Include RAND_status() into RAND_METHOD instead of implementing
      it only for md_rand.c  Otherwise replacing the PRNG by calling
      RAND_set_rand_method would be impossible.
