CHANGES

 291.	[func]		Caching servers no longer send outgoing queries
			over TCP just because the incoming recursive query
			was a TCP one.

 290.   [cleanup]	+twiddle option to dig (for testing only) removed.

 289.	[cleanup]	dig is now installed in $bindir instead of $sbindir.
			host is now installed in $bindir.  (Be sure to remove
			any $sbindir/dig from a previous release.)

 288.	[func]		rndc is now installed by "make install" into $sbindir.

 287.	[bug]		rndc now works again as "rndc 127.1 reload" (for
			only that task).  Parsing its configuration file and
			using digital signatures for authentication has been
			disabled until named supports the "controls" statement,
			post-9.0.0.

 286.	[bug]		On Solaris 2, when named inherited a signal state 
			where SIGHUP had the SIG_IGN action, SIGHUP would
			be ignored rather than causing the server to reload
			its configuration.

 285.	[bug]		A change made to the dst API for beta4 inadvertently
			broke OMAPI's creation of a dst key from an incoming
			message, causing an assertion to be triggered.  Fixed.

 284.	[func]		The DNSSEC key generation and signing tools now
			generate randomness from keyboard input on systems
			that lack /dev/random.

 283.	[cleanup]	The 'lwresd' program is now a link to 'named'.

 282.	[bug]		The lexer now returns ISC_R_RANGE if parsed integer is 
			too big for an usigned long.

 281.	[bug]		Fixed list of recognized config file category names.

 280.	[func]		Add isc-config.sh, which can be used to more
			easily build applications that link with
			our libraries.

 279.	[bug]		Private omapi function symbols shared between
			two or more files in libomapi.a were not namespace
			protected using the ISC convention of starting with
			the library name and two underscores ("omapi__"...)

 278.	[bug]		bin/named/logconf.c:category_fromconf() didn't take
			note of when isc_log_categorybyname() wasn't able
			to find the category name and would then apply the
			channel list of the unknown category to all categories.

 277.	[bug]		isc_log_categorybyname() and isc_log_modulebyname()
			would fail to find the first member of any category
			or module array apart from the internal defaults.
			Thus, for example, the "notify" category was improperly
			configured by named.

 276.	[bug]		dig now supports maximum sized TCP messages.

 275.	[bug]		The definition of lwres_gai_strerror() was missing 
			the lwres_ prefix.

 274.	[bug]		TSIG AXFR verify failed when talking to a BIND 8
			server.

 273.	[func]		The default for the 'transfer-format' option is
			now 'many-answers'.  This will break zone transfers
			to BIND 4.9.5 and older unless there is an explicit
			'one-answer' configuration.

 272.	[bug]		The sending of large TCP responses was canceled
			in mid-transmission due to a race condition
			caused by the failure to set the client object's
			"newstate" variable correctly when transitioning
			to the "working" state.

 271.	[func]		Attempt to probe the number of cpus in named
			if unspecified rather than defaulting to 1.

 270.	[func]		Allow maximum sized TCP answers.

 269.	[bug]		Failed DNSSEC validations could cause an assertion
			failure by causing clone_results() to be called with
			with hevent->node == NULL.

 268.	[doc]		A plain text version of the Administrator 
			Reference Manual is now included in the distribution,
			as doc/arm/Bv9ARM.txt.

 267.	[func]		Nsupdate is now provided in the distribution.

 266.	[bug]		zone.c:save_nsrrset() node was not initalized.

 265.	[bug]		dns_request_create() now works for TCP.

 264.	[func]		Dispatch can not take TCP sockets in connecting
			state.	Set DNS_DISPATCHATTR_CONNECTED when calling
			dns_dispatch_createtcp() for connected TCP sockets
			or call dns_dispatch_starttcp() when the socket is
			connected.

 263.	[func]		New logging channel type 'stderr'

				channel some-name {
					stderr;
					severity error;
				}

 262.	[bug]		'master' was not initalized in zone.c:stub_callback().

 261.	[func]		Add dns_zone_markdirty().

 260.	[bug]		Running named as a non-root user failed on Linux
			kernels new enough to support retaining capabilities
			after setuid().

 259.	[func]		New random-device and random-seed-file statements
			for global options block of named.conf. Both accept
			a single string argument.

 258.	[bug]		Fixed printing of lwres_addr_t.address field.

 257.	[bug]		The server detached the last zone manager reference
			too early, while it could still be in use by queries.
			This manifested itself as assertion failures during the
			shutdown process for busy name servers (RT #133).

 256.	[func]		isc_ratelimiter_t now has attach/detach semantics, and
			isc_ratelimiter_shutdown guarantees that the rate
			limiter is detached from its task.

 255.	[func]		New function dns_zonemgr_attach().

 254.	[bug]		Suppress "query denied" messages on additional data
			lookups.

	--- 9.0.0b4 released ---

 253.	[func]		resolv.conf parser now recognises ';' and '#' as
			comments (anywhere in line, not just as the beginning).

 252.	[bug]		resolv.conf parser mishandled masks on sortlists.
			It also aborted when an unrecognized keyword was seen,
			now it silently ignores the entire line.

 251.	[bug]		lwresd caught an assertion failure on startup.

 250.	[bug]		fixed handling of size+unit when value would be too
			large for internal representation.

 249.	[cleanup]	max-cache-size config option now takes a size-spec
			like 'datasize', except 'default' is not allowed.

 248.	[bug]		global lame-ttl option was not being printed when
			config structures were written out.

 247.	[cleanup]	Rename cache-size config option to max-cache-size.

 246.	[func]		Rename global option cachesize to cache-size and
			add corresponding option to view statement.

 245.	[bug]		If an uncompressed name will take more than 255
			bytes and the buffer is sufficiently long,
			dns_name_fromwire should return DNS_R_FORMERR,
			not ISC_R_NOSPACE.  This bug caused cause the
			server to catch an assertion failure when it
			received a query for a name longer than 255
			bytes.

 244.	[bug]		empty named.conf file and empty options statement are
			now parsed properly.

 243.	[func]		new cachesize option for named.conf

 242.	[cleanup]	fixed incorrect warning about auth-nxdomain usage.

 241.	[cleanup]	nscount and soacount have been removed from the
			dns_master_*() arguement lists.

 240.	[func]		databases now come in three flavours: zone, cache
			and stub.

 239.	[feature]	If ISC_MEM_DEBUG is enabled, the variable
			isc_mem_debugging controls whether messages
			are printed or not.

 238.	[cleanup]	A few more compilation warnings have been quieted:
			+ missing sigwait prototype on BSD/OS 4.0/4.0.1.
			+ PTHREAD_ONCE_INIT unbraced initializer warnings on
				Solaris 2.8.
			+ IN6ADDR_ANY_INIT unbraced initializer warnings on
				BSD/OS 4.*, Linux and Solaris 2.8.

 237.	[bug]		If connect() returned ENOBUFS when the resolver was
			initiating a TCP query, the socket didn't get
			destroyed, and the server did not shut down cleanly. 

 236.	[func]		Added new listen-on-v6 config file statement.

 235.	[func]		Consider it a config file error if a listen-on 
			statement has an IPv6 address in it, or a 
			listen-on-v6 statement has an IPv4 address in it.
			
 234.	[bug]		Allow a trusted-key's first field (domain-name) be
			either a quoted or an unquoted string, instead of
			requiring a quoted string.

 233.	[cleanup]	Convert all config structure integer values to unsigned
			integer (isc_uint32_t) to match grammer.

 232.	[bug]		Allow slave zones to not have a file.

 231.	[func]		Support new 'port' clause in config file options
			section. Causes 'listen-on', 'masters' and
			'also-notify' statements to use its value instead of
			default (53).

 230.	[func]		Replace the dst sign/verify API with a cleaner one.

 229.	[func]		Support config file sig-validity-interval statement 
			in options, views and zone statements (master 
			zones only).

 228.	[cleanup]	Logging messages in config module stripped of 
			trailing period.

 227.	[cleanup]	The enumerated identifiers dns_rdataclass_*,
			dns_rcode_*, dns_opcode_*, and dns_trust_* are
			also now cast to their appropriate types, as with
			dns_rdatatype_* in item number 225 below.

 226.	[func]		dns_name_totext() now always prints the root name as
			'.', even when omit_final_dot is true.

 225.	[cleanup]	The enumerated dns_rdatatype_* identifiers are now
			cast to dns_rdatatype_t via macros of their same name
			so that they are of the proper integral type wherever
			a dns_rdatatype_t is needed.

 224.	[cleanup]	The entire project builds cleanly with gcc's
			-Wcast-qual and -Wwrite-strings warnings enabled,
			which is now the default when using gcc.  (Warnings
			from confparser.c, because of yacc's code, are
			unfortunately to be expected.)

 223.	[func]		Several functions were reprototyped to qualify one
			or more of their arguments with "const".  Similarly,
			several functions that return pointers now have
			those pointers qualified with const.

 222.	[bug]		The global 'also-notify' option was ignored.

 221.	[bug]		An uninitialized variable was sometimes passed to
			dns_rdata_freestruct() when loading a zone, causing
			an assertion failure.

 220.	[cleanup]	Set the default outgoing port in the view, and
			set it in sockaddrs returned from the ADB.
			[31-May-2000 explorer]

 219.	[bug]		Signed truncated messages more correctly follow
			the respective specs.

 218.	[func]		When an rdataset is signed, its ttl is normalized
			based on the signature validity period.

 217.	[func]		Also-notify and trusted-keys can now be used in
			the 'view' statement.

 216.	[func]		The 'max-cache-ttl' and 'max-ncache-ttl' options 
			now work.

 215.	[bug]		Failures at certain points in request processing
			could cause the assertion INSIST(client->lockview
			== NULL) to be triggered.

 214.	[func]		New public function isc_netaddr_format(), for
			formatting network addresses in log messages.

 213.	[bug]		Don't leak memory when reloading the zone if
			an update-policy clause was present in the old zone.

 212.	[func]		Added dns_message_get/settsigkey, to make TSIG
			key management reasonable.

 211.	[func]		The 'key' and 'server' statements can now occur
			inside 'view' statements.

 210.	[bug]		The 'allow-transfer' option was ignored for slave
			zones, and the 'transfers-per-ns' option was
			was ignored for all zones.

 209.	[cleanup]	Upgraded openssl files to new version 0.9.5a

 208.	[func]		Added ISC_OFFSET_MAXIMUM for the maximum value
			of an isc_offset_t.

 207.	[func]		The dnssec tools properly use the logging subsystem.

 206.	[cleanup]	dst now stores the key name as a dns_name_t, not
			a char *.

 205.	[cleanup]	On IRIX, turn off the mostly harmless warnings 1692
			("prototyped function redeclared without prototype")
			and 1552 ("variable ... set but not used") when
			compiling in the lib/dns/sec/{dnssafe,openssl}
			directories, which contain code imported from outside
			sources.

 204.	[cleanup]	On HP/UX, pass +vnocompatwarnings to the linker
			to quiet the warnings that "The linked output may not
			run on a PA 1.x system."

 203.	[func]		notify and zone soa queries are now tsig signed when
			appropriate.

 202.	[func]		isc_lex_getsourceline() changed from returning int
			to returning unsigned long, the type of its underlying
			counter.

 201.	[cleanup]	Removed the test/sdig program, it has been
			replaced by bin/dig/dig.


	--- 9.0.0b3 released ---

 200.	[bug]		Failures in sending query responses to clients
			(e.g., running out of network buffers) were
			not logged.

 199.	[bug]		isc_heap_delete() sometimes violated the heap
			invariant, causing timer events not to be posted
			when due.

 198.	[func]		Dispatch managers hold memory pools which
			any managed dispatcher may use.	 This allows
			us to avoid dipping into the memory context for
			most allocations.  [19-May-2000 explorer]

 197.	[bug]		When an incoming AXFR or IXFR completes, the
			zone's internal state is refreshed from the
			SOA data.  [19-May-2000 explorer]

 196.	[func]		Dispatchers can be shared easily between views
			and/or interfaces.  [19-May-2000 explorer]

 195.	[bug]		Including the NXT record of the root domain
			in a negative response caused an assertion
			failure.

 194.	[doc]		The PDF version of the Administrator's Reference
			Manual is no longer included in the ISC BIND9
			distribution.

 193.	[func]		changed dst_key_free() prototype.

 192.	[bug]		Zone configuration validation is now done at end 
			of config file parsing, and before loading
			callbacks.

 191.	[func]		Patched to compile on UnixWare 7.x.  This platform
			is not directly supported by the ISC.

 190.	[cleanup]	The DNSSEC tools have been moved to a separate 
			directory dnssec/ and given the following new,
			more descriptive names:

			      dnssec-keygen
			      dnssec-signzone
			      dnssec-signkey
			      dnssec-makekeyset

			Their command line arguments have also been changed to
			be more consistent.  dnssec-keygen now prints the
			name of the generated key files (sans extension)
			on standard output to simplify its use in automated
			scripts.

 189.	[func]		isc_time_secondsastimet(), a new function, will ensure
			that the number of seconds in an isc_time_t does not
			exceed the range of a time_t, or return ISC_R_RANGE.
			Similarly, isc_time_now(), isc_time_nowplusinterval(),
			isc_time_add() and isc_time_subtract() now check the
			range for overflow/underflow.  In the case of
			isc_time_subtract, this changed a calling requirement
			(ie, something that could generate an assertion)
			into merely a condition that returns an error result.
			isc_time_add() and isc_time_subtract() were void-
			valued before but now return isc_result_t.

 188.	[func]		Log a warning message when an incoming zone transfer
			contains out-of-zone data.

 187.	[func]		isc_ratelimter_enqueue() has an additional arguement
			'task'.

 186.	[func]		dns_request_getresponse() has an additional arguement
			'preserve_order'.

 185.	[bug]		Fixed up handling of ISC_MEMCLUSTER_LEGACY.  Several
			public functions did not have an isc__ prefix, and
			referred to functions that had previously been
			renamed.

 184.	[cleanup]	Variables/functions which began with two leading
			underscores were made to conform to the ANSI/ISO
			standard, which says that such names are reserved.

 183.	[func]		ISC_LOG_PRINTTAG option for log channels.  Useful
			for logging the program name or other identifier.

 182.	[cleanup]	New commandline parameters for dnssec tools

 181.	[func]		Added dst_key_buildfilename and dst_key_parsefilename

 180.	[func]		New isc_result_t ISC_R_RANGE.  Supersedes DNS_R_RANGE.

 179.	[func]		options named.conf statement *must* now come
			before any zone or view statements.

 178.	[func]		Post-load of named.conf check verifies a slave zone
			has non-empty list of masters defined.

 177.	[func]		New per-zone boolean:

				enable-zone yes | no ;

			intended to let a zone be disabled without having
			to comment out the entire zone statement.

 176.	[func]		New global and per-view option:
				
				max-cache-ttl number

 175.	[func]		New global and per-view option:

				additional-data internal | minimal | maximal;

 174.	[func]		New public function isc_sockaddr_format(), for
			formatting socket addresses in log messages.

 173.	[func]		Keep a queue of zones waiting for zone transfer
			quota so that a new transfer can be dispatched
			immediately whenever quota becomes available.

 172.	[bug]		$TTL directive was sometimes missing from dumped 
			master files because totext_ctx_init() failed to
			initialize ctx->current_ttl_valid.

 171.	[cleanup]	On NetBSD systems, the mit-pthreads or
			unproven-pthreads library is now always used
			unless --with-ptl2 is explicitly specified on
			the configure command line.  The
			--with-mit-pthreads option is no longer needed
			and has been removed.

 170.	[cleanup]	Remove inter server consistancy checks from zone,
			these should return as a seperate module in 9.1.
			dns_zone_checkservers(), dns_zone_checkparents(),
			dns_zone_checkchildren(), dns_zone_checkglue().

			Remove dns_zone_setadb(), dns_zone_setresolver(),
			dns_zone_setrequestmgr() these should now be found
			via the view.

 169.	[func]		ratelimiter can now process N events per interval.

 168.	[bug]		include statements in named.conf caused syntax errors
			due to not consuming the semicolon ending the include
			statement before switching input streams.

 167.	[bug]		Make lack of masters for a slave zone a soft error.

 166.	[bug]		Keygen was overwriting existing keys if key_id
			conflicted, now it will retry, and non-null keys
			with key_id == 0 are not generated anymore.  Key
			was not able to generate NOAUTHCONF DSA key,
			increased RSA key size to 2048 bits.

 165.	[cleanup]	Silence "end-of-loop condition not reached" warnings
			from Solaris compiler.

 164.	[func]		Added functions isc_stdio_open(), isc_stdio_close(),
			isc_stdio_seek(), isc_stdio_read(), isc_stdio_write(),
			isc_stdio_flush(), isc_stdio_sync(), isc_file_remove()
			to encapsulate nonportable usage of errno and sync.

 163.	[func]		Added result codes ISC_R_FILENOTFOUND and
			ISC_R_FILEEXISTS.

 162.	[bug]		Ensure proper range for arguments to ctype.h functions.

 161.	[cleanup]	error in yyparse prototype that only HPUX caught.

 160.	[cleanup]	getnet*() are not going to be implemented at this
			stage.

 159.	[func]		Redefinition of config file elements is now an
			error (instead of a warning).

 158.	[bug]		Log channel and category list copy routines
			weren't assigning properly to output parameter.

 157.	[port]		Fix missing prototype for getopt().

 156.	[func]		Support new 'database' statement in zone.

				database "quoted-string";

 155.	[bug]		ns_notify_start() was not detaching the found zone.

 154.	[func]		The signer now logs libdns warnings to stderr even when
			not verbose, and in a nicer format.

 153.	[func]		dns_rdata_tostruct() 'mctx' is now optional.  If 'mctx'
			is NULL then you need to preserve the 'rdata' until
			you have finished using the structure as there may be
			references to the associated memory.  If 'mctx' is 
			non-NULL it is guaranteed that there are no references
			to memory associated with 'rdata'.

			dns_rdata_freestruct() must be called if 'mctx' was
			non-NULL and may safely be called if 'mctx' was NULL.

 152.	[bug]		keygen dumped core if domain name argument was omitted
			from command line.

 151.	[func]		Support 'disabled' statement in zone config (causes
			zone to be parsed and then ignored). Currently must
			come after the 'type' clause.

 150.	[func]		Support optional ports in masters and also-notify
			statements: 

				masters [ port xxx ] { y.y.y.y [ port zzz ] ; }

 149.	[cleanup]	Removed usused argument 'olist' from
			dns_c_view_unsetordering().

 148.	[cleanup]	Stop issuing some warnings about some configuration
			file statements that were not implemented, but now are.

 147.	[bug]		Changed yacc union size to be smaller for yaccs that
			put yacc-stack on the real stack.

 146.	[cleanup]	More general redundant header file cleanup.  Rather
			than continuing to itemize every header which changed,
			this changelog entry just notes that if a header file
			did not need another header file that it was including
			in order to provide its advertized functionality, the
			inclusion of the other header file was removed.	 See
			util/check-includes for how this was tested.

 145.	[cleanup]	Added <isc/lang.h> and ISC_LANG_BEGINDECLS/
			ISC_LANG_ENDDECLS to header files that had function
			prototypes, and removed it from those that did not.

 144.	[cleanup]	libdns header files too numerous to name were made
			to conform to the same style for multiple inclusion
			protection.

 143.	[func]		Added function dns_rdatatype_isknown().

 142.	[cleanup]	<isc/stdtime.h> does not need <time.h> or
			<isc/result.h>.

			cause an assertion failure.

 140.	[cleanup]	<isc/time.h> does not need <time.h> or <isc/result.h>.

			<isc/int.h> and <isc/result.h>.

 138.	[cleanup]	isc_strtouq moved from str.[ch] to string.[ch] and
			renamed isc_string_touint64.  isc_strsep moved from
			strsep.c to string.c and renamed isc_string_separate.

 137.	[cleanup]	<isc/commandline.h>, <isc/mem.h>, <isc/print.h>
			<isc/serial.h>, <isc/string.h> and <isc/offset.h>
			made to conform to the same style for multiple
			inclusion protection.

 136.	[cleanup]	<isc/commandline.h>, <isc/interfaceiter.h>,
			<isc/net.h> and Win32's <isc/thread.h> needed
			ISC_LANG_BEGINDECLS/ISC_LANG_ENDDECLS.

 135.	[cleanup]	Win32's <isc/condition.h> did not need <isc/result.h>
			or <isc/boolean.h>, now uses <isc/types.h> in place
			of <isc/time.h>, and needed ISC_LANG_BEGINDECLS
			and ISC_LANG_ENDDECLS.

 134.	[cleanup]	<isc/dir.h> does not need <limits.h>.

 133.	[cleanup]	<isc/ipv6.h> needs <isc/platform.h>.

 132.	[cleanup]	<isc/app.h> does not need <isc/task.h>, but does
			need <isc/eventclass.h>.

 131.	[cleanup]	<isc/mutex.h> and <isc/util.h> need <isc/result.h>
			for ISC_R_* codes used in macros.

 130.	[cleanup]	<isc/condition.h> does not need <pthread.h> or
			<isc/boolean.h>, and now includes <isc/types.h>
			instead of <isc/time.h>.

 129.	[bug]		The 'default_debug' log channel was not set up when
			'category default' was present in the config file

 128.	[cleanup]	<isc/dir.h> had ISC_LANG_BEGINDECLS instead of
			ISC_LANG_ENDDECLS at end of header.

 127.	[cleanup]	The contracts for the comparision routines
			dns_name_fullcompare(), dns_name_compare(),
			dns_name_rdatacompare(), and dns_rdata_compare() now
			specify that the order value returned is < 0, 0, or > 0
			instead of -1, 0, or 1.

 126.	[cleanup]	<isc/quota.h> and <isc/taskpool.h> need <isc/lang.h>.

 125.	[cleanup]	<isc/eventclass.h>, <isc/ipv6.h>, <isc/magic.h>,
			<isc/mutex.h>, <isc/once.h>, <isc/region.h>, and
			<isc/resultclass.h> do not need <isc/lang.h>.

 124.	[func]		signer now imports parent's zone key signature

			dns_zone_clearnotify() and dns_zone_addnotify()
			are replaced by dns_zone_setnotifyalso().
			dns_zone_clearmasters() and dns_zone_addmaster()
			are replaced by dns_zone_setmasters().
			
 116.	[func]		Added <isc/offset.h> for isc_offset_t (aka off_t
			on Unix systems).

 115.	[port]		Shut up the -Wmissing-declarations warning about
			<stdio.h>'s __sputaux on BSD/OS pre-4.1.

 114.	[cleanup]	<isc/sockaddr.h> does not need <isc/buffer.h> or

				isc_buffer_current(b)	    (pointer)
				isc_buffer_active(b)	    (pointer)
				isc_buffer_used(b)	    (pointer)
				isc_buffer_length(b)		(int)
				isc_buffer_usedlength(b)	(int)
				isc_buffer_consumedlength(b)	(int)
				isc_buffer_remaininglength(b)	(int)
				isc_buffer_activelength(b)	(int)

				isc_buffer_type(b)
			Changed names:
				isc_buffer_used(b, r) ->
					isc_buffer_usedregion(b, r)
				isc_buffer_available(b, r) ->
					isc_buffer_available_region(b, r)
				isc_buffer_consumed(b, r) ->
					isc_buffer_consumedregion(b, r)
				isc_buffer_active(b, r) ->
					isc_buffer_activeregion(b, r)
				isc_buffer_remaining(b, r) ->

			Buffer types were removed, so the ISC_BUFFERTYPE_*
			macros are no more, and the type argument to
			isc_buffer_init and isc_buffer_allocate were removed.
			isc_buffer_putstr is now void (instead of isc_result_t)
			and requires that the caller ensure that there
			is enough available buffer space for the string.

  72.	[func]		DNS_RBTFIND_NOPREDECESSOR and DNS_RBTFIND_NOOPTIONS
			added for dns_rbt_findnode, the former to disable the
			setting of the chain to the predecessor, and the
			latter to make clear when no options are set.

  71.	[cleanup]	Made explicit the implicit REQUIREs of
			isc_time_seconds, isc_time_nanoseconds, and

  53.	[port]		freebsd 4.0: lib/isc/unix/socket.c requires
			<sys/param.h>.

  52.	[bug]		rndc: taskmgr and socketmgr were not initialized
			to NULL.

  51.	[cleanup]	dns/compress.h and dns/zt.h did not need to include

			and dns_rbt_deletenode was added.

  49.	[func]		Each cache now has its own mctx.

			counting.

  46.	[func]		Memory contexts are now reference counted.
			Added isc_mem_inuse() and isc_mem_preallocate().
			Renamed isc_mem_destroy_check() to
			isc_mem_setdestroycheck().

  45.	[bug]		The trusted-key statement incorrectly loaded keys.

			logging module "dns/validator".

  39.	[cleanup]	Moved the typedefs for isc_region_t, isc_textregion_t, 
			and isc_lex_t to <isc/types.h>.

  38.	[bug]		TSIG signed incoming zone transfers work now.

  37.	[bug]		If the first RR in an incoming zone transfer was 
			not an SOA, the server died with an assertion failure
			instead of just reporting an error.

  36.	[cleanup]	Change DNS_R_SUCCESS (and others) to ISC_R_SUCCESS

  35.	[performance]	Log messages which are of a level too high to be

			config global options.
			
  27.	[bug]		Only include <netinet6/in6.h> on BSD/OS 4.[01]*.

			requests, using a new function ns_client_log().

  22.	[bug]		SIGs weren't returned in the answer section when
			the query resulted in a fetch.

  21.	[port]		Look at STD_CINCLUDES after CINCLUDES during
			compilation, so additional system include directories
			can be searched but header files in the bind9 source
			tree with conflicting names take precedence.  This
			avoids issues with installed versions of dnssafe and
			openssl.

  20.	[func]		Configuration file post-load validation of zones
			failed if there were no zones.

  19.	[bug]		dns_zone_notifyreceive() failed to unlock the zone
			lock in certain error cases.

  18.	[bug]		Use AC_TRY_LINK rather than AC_TRY_COMPILE in
			configure.in to check for presence of in6addr_any.

  17.	[func]		Do configuration file post-load validation of zones.

  16.	[bug]		put quotes around key names on config file 
			output to avoid possible keyword clashes.
