 299.	[cleanup]	Get the user and group information before changing the
			root directory, so the administrator does not need to
			keep a copy of the user and group databases in the
			chroot'ed environment.  Suggested by Hakan Olsson.

6 7 8 9
 298.	[bug]		A mutex deadlock occurred during shutdown of the
			interface manager under certain conditions.
			Digital Unix systems were the most affected.

10 11 12
 297.	[bug]		Specifying a key name that wasn't fully qualified
			in certain parts of the config file could cause
			an assertion.
13

14 15 16 17
 296.	[bug]		"make install" from a separate build directory
			failed unless configure had been run in the source
			directory, too.

18 19 20 21 22 23 24 25
 295.	[bug]		When invoked with type==CNAME and a message
			not constructed by dns_message_parse(),
			dns_message_findname() failed to find anything
			due to checking for attribute bits that are set
			only in dns_message_parse().   This caused an
			infinite loop when constructing the response to
			an ANY query at a CNAME in a secure zone.

26 27 28 29 30
 294.	[bug]		If we run out of space in while processing glue
			when reading a master file and commit "current name"
			reverts to "name_current" instead of staying as
			"name_glue".

31
 293.	[port]		Add support for FreeBSD 4.0 system tests.
32

33 34 35 36 37 38 39
 292.	[bug]		Due to problems with the way some operating systems
			handle simultaneous listening on IPv4 and IPv6
			addresses, the server no longer listens on IPv6
			addresses by default.  To revert to the previous
			behavior, specify "listen-on-v6 { any; };" in
			the config file.

40 41 42 43
 291.	[func]		Caching servers no longer send outgoing queries
			over TCP just because the incoming recursive query
			was a TCP one.

44 45
 290.   [cleanup]	+twiddle option to dig (for testing only) removed.

46 47 48 49 50 51 52 53 54
 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,
56 57
			post-9.0.0.

58 59 60 61 62
 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.

63 64 65 66
 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.

67 68 69 70 71 72
 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'.

73
 282.	[bug]		The lexer now returns ISC_R_RANGE if parsed integer is 
74
			too big for an unsigned long.
75

76
 281.	[bug]		Fixed list of recognized config file category names.

			our libraries.

82 83 84 85
 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__"...)
86

87 88 89 90
 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.
91

92 93 94 95 96
 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.
97

			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.

111 112 113 114 115 116
 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.

 270.	[func]		Allow maximum sized TCP answers.

122 123 124 125
 269.	[bug]		Failed DNSSEC validations could cause an assertion
			failure by causing clone_results() to be called with
			with hevent->node == NULL.

126 127 128 129

			Reference Manual is now included in the distribution,

 265.	[bug]		dns_request_create() now works for TCP.
135 136 137 138 139 140 141

 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.

142 143 144 145 146 147 148

				channel some-name {
					stderr;

152

153 154 155 156
 260.	[bug]		Running named as a non-root user failed on Linux
			kernels new enough to support retaining capabilities
			after setuid().

157 158 159 160
 259.	[func]		New random-device and random-seed-file statements
			for global options block of named.conf. Both accept
			a single string argument.

161 162
 258.	[bug]		Fixed printing of lwres_addr_t.address field.

163 164
 257.	[bug]		The server detached the last zone manager reference
			too early, while it could still be in use by queries.
165
			This manifested itself as assertion failures during the
166 167 168 169 170 171 172 173
			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().

238 239 240 241 242 243
 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.
			
244 245 246 247
 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.

248 249 250
 233.	[cleanup]	Convert all config structure integer values to unsigned
			integer (isc_uint32_t) to match grammer.

251 252
 232.	[bug]		Allow slave zones to not have a file.

253 254 255 256 257

 229.	[func]		Support config file sig-validity-interval statement

			zones only).

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

267 268 269 270

			dns_rdatatype_* in item number 225 below.
271 272 273

 226.	[func]		dns_name_totext() now always prints the root name as
			'.', even when omit_final_dot is true.
274

275 276 277 278
 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.
279

280 281 282 283 284
 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.)
285

286 287 288 289

			or more of their arguments with "const".  Similarly,
			several functions that return pointers now have
			those pointers qualified with const.

			not logged.

371 372 373 374
 199.	[bug]		isc_heap_delete() sometimes violated the heap
			invariant, causing timer events not to be posted
			when due.

375
 198.	[func]		Dispatch managers hold memory pools which
376
			any managed dispatcher may use.	 This allows

387 388 389 390
 195.	[bug]		Including the NXT record of the root domain

			      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

			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-

 185.	[bug]		Fixed up handling of ISC_MEMCLUSTER_LEGACY.  Several
			public functions did not have an isc__ prefix, and

444

445 446 447
 184.	[cleanup]	Variables/functions which began with two leading

			for logging the program name or other identifier.
