 436.	[bug]		If recvmsg() returned EHOSTUNREACH or ENETUNREACH,
			which sometimes happens on Linux, named would enter
			a busy loop.  Also, unexpected socket errors were
			not logged at a high enough logging level to be
7
			useful in diagnosing this situation. [RT #275]

 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]

 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.

38
 429.	[bug]		The space reserved for a TSIG record in a response
			was 2 bytes too short, leading to message
			generation failures.

42
43
 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.

44

 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

 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.

71
 421.	[bug]		nslookup would exit when given a blank line as input.

72
73
 420.	[bug]		nslookup failed to implement the "exit" command.

83
 417.	[func]		Add isc_app_block() and isc_app_unblock(), which
			allow an application to handle signals while
			blocking.		

84
85

			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.

140
141
142

			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

			an argc/argv style vector of words and sets 
			both the zone database type and its arguments,
			making the functions dns_zone_adddbarg()

			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
