                        + missing sigwait prototype on BSD/OS 4.0/4.0.1.

 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.

 234.	[bug]		Allow a trusted-key's first field (domain-name) be

                        dns_rcode_*, dns_opcode_*, and dns_trust_* are
                        also now cast to their appropriate types, as with
                        dns_rdatatype_* in item number 225 below.

 226.	[func]		dns_name_totext() now always prints the root name as

                        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.

 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.)

 223.   [func]          Several functions were reprototyped to qualify one
                        or more of their arguments with "const".  Similarly,
                        several functions that return pointers now have
                        those pointers qualified with const.

                        ("prototyped function redeclared without prototype")
                        and 1552 ("variable ... set but not used") when
                        compiling in the lib/dns/sec/{dnssafe,openssl}
                        directories, which contain code imported from outside

 198.	[func]		Dispatch managers hold memory pools which
			any managed dispatcher may use.  This allows
			us to avoid dipping into the memory context for
			most allocations.  [19-May-2000 explorer]

 197.	[bug]		When an incoming AXFR or IXFR completes, the
			zone's internal state is refreshed from the
			SOA data.  [19-May-2000 explorer]

 196.	[func]		Dispatchers can be shared easily between views
			and/or interfaces.  [19-May-2000 explorer]

211

227
 191.   [func]          Patched to compile on UnixWare 7.x.  This platform
                        is not directly supported by the ISC.

 190.   [cleanup]	The DNSSEC tools have been moved to a separate 
			directory dnssec/ and given the following new,
			more descriptive names:

			      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
			name of the generated key files (sans extension)
			on standard output to simplify its use in automated
			scripts.

 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.

 185.   [bug]           Fixed up handling of ISC_MEMCLUSTER_LEGACY.  Several
                        public functions did not have an isc__ prefix, and
                        referred to functions that had previously been
                        renamed.

 184.   [cleanup]       Variables/functions which began with two leading
                        underscores were made to conform to the ANSI/ISO
                        standard, which says that such names are reserved.
272

 183.   [func]          ISC_LOG_PRINTTAG option for log channels.  Useful
                        for logging the program name or other identifier.

 146.   [cleanup]       More general redundant header file cleanup.  Rather
                        than continuing to itemize every header which changed,
                        this changelog entry just notes that if a header file
                        did not need another header file that it was including
                        in order to provide its advertized functionality, the
                        inclusion of the other header file was removed.  See
                        util/check-includes for how this was tested.

                        prototypes, and removed it from those that did not.

                        isc_buffer_init and isc_buffer_allocate were removed.
                        isc_buffer_putstr is now void (instead of isc_result_t)
                        and requires that the caller ensure that there
                        is enough available buffer space for the string.
