  Changes between 0.9.5a and 0.9.6  [xx XXX 2000]
 
+  *) In ssl23_get_client_hello, generate an error message when faced
+     with an initial SSL 3.0/TLS record that is too small to contain the
+     first two bytes of the ClientHello message, i.e. client_version.
+     (Note that this is a pathologic case that probably has never happened
+     in real life.)  The previous approach was to use the version number
+     from the record header as a substitute; but our protocol choice
+     should not depend on that one because it is not authenticated
+     by the Finished messages.
+     [Bodo Moeller]
+
+  *) For compatibility reasons if the flag X509_V_FLAG_ISSUER_CHECK is
+     not set then we don't setup the error code for issuer check errors
+     to avoid possibly overwriting other errors which the callback does
+     handle. If an application does set the flag then we assume it knows
+     what it is doing and can handle the new informational codes
+     appropriately.
+     [Steve Henson]
+
   *) Fix for a nasty bug in ASN1_TYPE handling. ASN1_TYPE is used for
      a general "ANY" type, as such it should be able to decode anything
      including tagged types. However it didn't check the class so it would
