This is a summary of the implementation status of the various named.conf
options in BIND 9.

Legend:

  Yes	    Implemented in this release.

  No	    Not implemented, may be implemented in a later release.

  Obsolete  Obsolete, not applicable to BIND 9, or just evil.
	    Will not be implemented.

  *	    New in BIND 9.

  +	    The option is now always enabled.

  -	    The option is now always disabled.

  %	    The default value has changed since BIND 8.

  &	    The option has been extended since BIND 8.

  @	    Semantics of certain pathological address match lists, in
	    particular those involving double negation, have changed.
	    The new semantics are generally safer.  IPv6 addresses
	    are supported, but the predefined ACLs "localhost" and
	    "localnets" match IPv4 addresses only.

  #	    BIND 9 accepts both LF and CRLF as end-of-line markers.

  $	    Stub zones are partially supported.	 They no longer
	    inject NS records into their parent zones, but can still
	    be used as a way of forcing a domain to be resolved using
	    a particular set of name servers.
