  Upgrading
  ---------
+     - Before you upgrade, if you are using 
`cassandra.auth_bcrypt_gensalt_log2_rounds` property,
+       confirm it is set to value lower than 31 otherwise Cassandra will fail 
to start. See CASSANDRA-9384
+       for further details. You also need to regenerate passwords for users 
for who the password
+       was created while the above property was set to be more than 30 
otherwise they will not be able to log in.
