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

 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.

 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.

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

 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]

 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.

35
36
 421.	[bug]		nslookup would exit when given a blank line as input.

37
38
 420.	[bug]		nslookup failed to implement the "exit" command.

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

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

 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.

105
106
107

			using TSIG, depending on the key length.

 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.

 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

 344.	[bug]		When shutting down, lwresd sometimes tried
278

 324.	[func]		In the resolver, turn EDNS0 off if there is no

			This is to allow queries some chance of succeeding

 309.	[bug]		When sending a referral, the server did not look

 307.	[bug]		When canceling a query, the resolver didn't check for
