   * <!DOCTYPE (ie DTD) is not supported.
 
 ### Corrected Bugs
+* Keyword "min" (not only "max") can be used in built-in types "range" and "length" statements.
 * Support for empty yang string added, eg `default "";`
 * Removed CLI generation for yang notifications (and other non-data yang nodes)
 * Some restconf error messages contained "rpc-reply" or "rpc-error" which have now been removed.
