 435.	[bug]		dns_zone_dump() overwrote existing zone files 
			rather than writing to a temporary file and
			renaming.  This could lead to empty or partial
			zone files being left around in certain error
			conditions involving the initial transfer of a
			slave zone, interfering with subsequent server
			startup. [RT #282]

 434.	[func]		New function isc_file_isabsolute().

16
 433.	[func]		isc_base64_decodestring() now accepts newlines
			within the base64 data.  This makes it possible 
			to break up the key data in a "trusted-keys"
			statement into multiple lines. [RT #284]

 432.	[func]		Added refresh/retry jitter.  This is currently
			hard-coded to be no more than 20% of the SOA
			provided time or 10 minutes, whichever is less.

 431.	[func]		Log at ISC_LOG_INFO when a zone is successfully
			loaded.

 430.	[bug]		Rewrote the lightweight resolver client management
			code to handle shutdown correctly and general
			cleanup.

 429.	[bug]		The space reserved for a TSIG record in a response
			was 2 bytes too short, leading to message
			generation failures.

32

34
35
36
 428.   [bug]		rbtdb.c:find_closest_nxt() erroneously returned
			DNS_R_BADDB for nodes which had neither NXT nor SIG NXT
			(e.g. glue).  This could cause SERVFAILs when
			generating negative responses in a secure zone.

37

 427.	[bug]		Avoid going into an infinite loop when the validator
			gets a negative response to a key query where the
			records are signed by the missing key.

41
42
43
 426.	[bug]		Attempting to generate an oversized RSA key could
			cause dnssec-keygen to dump core.

44
45
46
 425.	[bug]		Warn about the auth-nxdomain default value change
			if there is no auth-nxdomain statement in the
			config file. [RT #287]

 424.	[bug]		notify_createmessage() could trigger an assertion
			failure when creating the notify message failed,
			e.g. due to corrupt zones with multiple SOA records.
			[RT #279]

 423.	[bug]		When responding to a recusive query, errors that occur
			after following a CNAME should cause the query to fail.
			[RT #274]

61
62
 422.	[func]		get rid of isc_random_t, and make isc_random_get()
			and isc_random_jitter() use rand() internally
			instead of local state.  Note that isc_random_*()
			functions are only for weak, non-critical "randomness"
			such as timing jitter and such.

63
64
 421.	[bug]		nslookup would exit when given a blank line as input.

65
66
 420.	[bug]		nslookup failed to implement the "exit" command.

67
68
 419.	[bug]		The certificate type PKIX was misspelled as SKIX.

69
70
71
72
 418.	[bug]		At debug levels >= 10, getting an unexpected
			socket receive error would crash the server
			while trying to log the error message.

73
74
75
76
 417.	[func]		Add isc_app_block() and isc_app_unblock(), which
			allow an application to handle signals while
			blocking.		

77
78
 416.	[bug]		Slave zones with no master file tried to use a
			NULL pointer for a journal file name when they

			received an IXFR. [RT #273]
80

81
82
 415.	[bug]		The logging code leaked file descriptors.

83
84
85
 414.	[bug]		Server did not shut down until all incoming zone 
			transfers were finished.

86
87
 413.	[bug]		Notify could attempt to use the zone database after
			it had been unloaded. [RT#267]

116
117
118
119

131
132
 399.	[bug]		When reloading the server with a config file
			containing a syntax error, it could catch an
			assertion failure trying to perform zone
			maintenance on, or sending notifies from,
			tentatively created zones whose	views were
			never fully configured and lacked an address 
			database and request manager.

133
134
135
 398.	[bug]		"dig" sometimes caught an assertion failure when
			using TSIG, depending on the key length.

153
 394.	[bug]		Current name was not propagated via $INCLUDE.

 393.	[func]		Initial answer while loading (awl) support.
			Entry points: dns_master_loadfileinc(),
			dns_master_loadstreaminc(), dns_master_loadbufferinc().
			Note: calls to dns_master_load*inc() should be rate
			be rate limited so as to not use up all file
			descriptors.

154
155
156
157
158
 392.	[func]		Add ISC_R_FAMILYNOSUPPORT.  Returned when OS does

161
162
163
 390.	[func]		The function dns_zone_setdbtype() now takes
			an argc/argv style vector of words and sets 
			both the zone database type and its arguments,
			making the functions dns_zone_adddbarg()
			and dns_zone_cleardbargs() unnecessary.

 361.	[func]		When the RBT find or chain functions set the name and
			origin for a node that stores the root label
			the name is now set to an empty name, instead of ".",
			to simplify later use of the name and origin by
			dns_name_concatenate(), dns_name_totext() or
			dns_name_format().

 360.	[func]		dns_name_totext() and dns_name_format() now allow
			an empty name to be passed, which is formatted as "@".

256
257

304
305

 344.	[bug]		When shutting down, lwresd sometimes tried
306

			when configured for the server in case,
			the TSIG was not verified on the response.

338
339
340

379
 324.	[func]		In the resolver, turn EDNS0 off if there is no
			response after a number of retransmissions.
			This is to allow queries some chance of succeeding

383
 323.	[bug]		dns_rbt_findname() did not ignore empty rbt nodes.
384

424
425
			still return an error if one was found.

426
427

429
430
 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.

			subtype only)

			  - support "keys" clause

				controls {
				   inet * port 1024

 309.	[bug]		When sending a referral, the server did not look
			for name server addresses as glue in the zone

 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.
