  Changes between 0.9.1c and 0.9.2
 
+  *) Overhaul for 'crl' utility. New function X509_CRL_print. Partial support
+     for some CRL extensions and new objects added.
+     [Steve Henson]
+
   *) Really fix the ASN1 IMPLICIT bug this time... Partial support for private
      key usage extension and fuller support for authority key id.
