 314.	[func]		Inet controls named.conf statement can now have 
			any non-negative number of keys specified.

4 5 6 7
 313.	[bug]		When parsing resolv.conf, don't terminate on an
			error.  Instead, parse as much as possible, but
			still return an error if one was found.

8 9 10 11 12
 312.	[bug]		Increase the number of allowed elements in the
			resolv.conf search path from 6 to 8.  If there
			are more than this, ignore the remainder rather
			than returning a failure in lwres_conf_parse.

13 14 15
 311.	[bug]		lwres_conf_parse failed when the first line of
			resolv.conf was empty or a comment.

16 17 18 19 20 21 22 23 24 25 26 27 28 29
 310.	[func]		Changes to named.conf "controls" statement (inet
			subtype only)

			  - support "keys" clause

				controls {
				   inet * port 1024
					allow { any; } keys { "foo"; }
				}

			  - allow "port xxx" to be left out of statement,
			    in which case it defaults to omapi's default port
			    of 953.
 
30 31 32 33 34 35
 309.	[bug]		When sending a referral, the server did not look
			for name server addresses as glue in the zone
			holding the NS RRset in the case where this zone
			was not the same as the one where it looked for
			name server addresses as authoritative data.

36 37 38
 308.	[bug]		Treat a SOA record not at top of zone as an error
			when loading a zone. (RT #154)

39 40 41 42 43 44 45
 307.	[bug]		When canceling a query, the resolver didn't check for
			isc_socket_sendto() calls that did not yet have their
			completion events posted, so it could (rarely) end up
			destroying the query context and then want to use
			it again when the send event posted, triggering an
			assertion as it tried to cancel an already-canceled
			query.  (RT #77)

 306.	[bug] 		Reading HMAC-MD5 private key files didn't work.

			assertion failure trying to perform zone
			maintenance on tentatively created zones whose
			views were never fully configured and lacked
			an address database.

56 57 58 59
 304.	[bug]		If more than LWRES_CONFMAXNAMESERVERS servers
			are listed in resolv.conf, silently ignore them
			instead of returning failure.

60
 303.	[bug]		Add additional sanity checks to differentiate a AXFR
61 62

68

69 70 71 72 73 74
 300.	[bug]		Using both <isc/net.h> and <lwres/net.h> didn't work
			on platforms lacking IPv6 because each included their
			own ipv6 header file for the missing definitions.  Now
			each library's ipv6.h defines the wrapper symbol of
			the other (ISC_IPV6_H and LWRES_IPV6_H).

75 76 77 78 79
 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.

80 81 82 83
 298.	[bug]		A mutex deadlock occurred during shutdown of the
			interface manager under certain conditions.
			Digital Unix systems were the most affected.

84 85 86
 297.	[bug]		Specifying a key name that wasn't fully qualified
			in certain parts of the config file could cause
			an assertion.
87

88 89 90 91
 296.	[bug]		"make install" from a separate build directory
			failed unless configure had been run in the source
			directory, too.

92 93 94 95 96 97 98 99
 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.

100 101 102 103 104
 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".

105
 293.	[port]		Add support for FreeBSD 4.0 system tests.
106

107 108 109 110 111 112 113
 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.

114 115 116 117
 291.	[func]		Caching servers no longer send outgoing queries
			over TCP just because the incoming recursive query
			was a TCP one.

118 119
 290.   [cleanup]	+twiddle option to dig (for testing only) removed.

120 121 122 123 124 125 126 127 128
 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

132 133 134 135 136
 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.

137 138 139 140
 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.

141 142 143 144 145 146
 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'.

147
 282.	[bug]		The lexer now returns ISC_R_RANGE if parsed integer is 
148
			too big for an unsigned long.

 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__"...)
160

161 162 163 164
 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.
165

 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.

 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.

185 186 187 188 189 190
 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.

 264.	[func]		Dispatch can not take TCP sockets in connecting
			state.	Set DNS_DISPATCHATTR_CONNECTED when calling
			dns_dispatch_createtcp() for connected TCP sockets

			connected.

237 238
 257.	[bug]		The server detached the last zone manager reference
			too early, while it could still be in use by queries.
239
			This manifested itself as assertion failures during the
240 241 242 243 244 245 246 247
			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.

			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

			isc_time_add() and isc_time_subtract() were void-
