2006-11-03  Bob Halley  <halley@dnspython.org>

	* dns/rdtypes/IN/DHCID.py: Added support for the DHCID RR type.

2006-11-02  Bob Halley  <halley@dnspython.org>

	* dns/query.py (udp): Messages from unexpected sources can now be
	  ignored by setting ignore_unexpected to True.

2006-10-31  Bob Halley  <halley@dnspython.org>

	* dns/query.py (udp): When raising UnexpectedSource, add more
	  detail about what went wrong to the exception.

2006-09-22  Bob Halley  <halley@dnspython.org>

	* dns/message.py (Message.use_edns): add reasonable defaults for
	  the ednsflags, payload, and request_payload parameters.

	* dns/message.py (Message.want_dnssec): add a convenience method for
	  enabling/disabling the "DNSSEC desired" flag in requests.

	* dns/message.py (make_query): add "use_edns" and "want_dnssec"
	  parameters.

2006-08-17  Bob Halley  <halley@dnspython.org>

	* dns/resolver.py (Resolver.read_resolv_conf): If /etc/resolv.conf
	  doesn't exist, just use the default resolver configuration (i.e.
	  the same thing we would have used if resolv.conf had existed and
	  been empty).

2006-07-26  Bob Halley  <halley@dnspython.org>

	* dns/resolver.py (Resolver._config_win32_fromkey): fix
	  cut-and-paste error where we passed the wrong variable to
	  self._config_win32_search().  Thanks to David Arnold for finding
	  the bug and submitting a patch.

2006-07-20  Bob Halley  <halley@dnspython.org>

	* dns/resolver.py (Answer): Add more support for the sequence
	  protocol, forwarding requests to the answer object's rrset.
	  E.g. "for a in answer" is equivalent to "for a in answer.rrset",
	  "answer[i]" is equivalent to "answer.rrset[i]", and
	  "answer[i:j]" is equivalent to "answer.rrset[i:j]".

2006-07-19  Bob Halley  <halley@dnspython.org>

	* dns/query.py (xfr): Add IXFR support.

2006-06-22  Bob Halley  <halley@dnspython.org>

	* dns/rdtypes/IN/IPSECKEY.py: Added support for the IPSECKEY RR type.

2006-06-21  Bob Halley  <halley@dnspython.org>

	* dns/rdtypes/ANY/SPF.py: Added support for the SPF RR type.

2006-06-02  Bob Halley  <halley@dnspython.org>

	* (Version 1.4.0 released)

2006-04-25  Bob Halley  <halley@dnspython.org>

	* dns/rrset.py (RRset.to_rdataset): Added a convenience method
	  to convert an rrset into an rdataset.

2006-03-27  Bob Halley  <halley@dnspython.org>

	* Added dns.e164.query().  This function can be used to look for
	  NAPTR RRs for a specified number in several domains, e.g.:

		dns.e164.query('16505551212',
			       ['e164.dnspython.org.', 'e164.arpa.'])

2006-03-26  Bob Halley  <halley@dnspython.org>

	* dns/resolver.py (Resolver.query): The resolver deleted from
	  a list while iterating it, which makes the iterator unhappy.

2006-03-17  Bob Halley  <halley@dnspython.org>

	* dns/resolver.py (Resolver.query): The resolver needlessly
	  delayed responses for successful queries.

2006-01-18  Bob Halley  <halley@dnspython.org>

	* dns/rdata.py: added a validate() method to the rdata class.  If
	  you change an rdata by assigning to its fields, it is a good
	  idea to call validate() when you are done making changes.
	  For example, if 'r' is an MX record and then you execute:

		r.preference = 100000   # invalid, because > 65535
		r.validate()

	  The validation will fail and an exception will be raised.

2006-01-11  Bob Halley  <halley@dnspython.org>

	* dns/ttl.py: TTLs are now bounds checked to be within the closed
	  interval [0, 2^31 - 1].

	* The BIND 8 TTL syntax is now accepted in the SOA refresh, retry,
	  expire, and minimum fields, and in the original_ttl field of
	  SIG and RRSIG records.

2006-01-04  Bob Halley  <halley@dnspython.org>

	* dns/resolver.py: The windows registry irritatingly changes the
	  list element delimiter in between ' ' and ',' (and vice-versa)
	  in various versions of windows.  We now cope by always looking
	  for either one (' ' first).

2005-12-27  Bob Halley  <halley@dnspython.org>

	* dns/e164.py: Added routines to convert between E.164 numbers and
	  their ENUM domain name equivalents.

	* dns/reversename.py: Added routines to convert between IPv4 and
	  IPv6 addresses and their DNS reverse-map equivalents.

2005-12-18  Bob Halley  <halley@dnspython.org>

	* dns/rdtypes/ANY/LOC.py (_tuple_to_float): The sign was lost when
	  converting a tuple into a float, which broke conversions of
	  south latitudes and west longitudes.

2005-11-17  Bob Halley  <halley@dnspython.org>

	* dns/zone.py: The 'origin' parameter to from_text() and from_file()
	  is now optional.  If not specified, dnspython will use the
	  first $ORIGIN in the text as the zone's origin.

	* dns/zone.py: Sanity checks of the zone's origin node can now
	  be disabled.

2005-11-12  Bob Halley  <halley@dnspython.org>

	* dns/name.py: Preliminary Unicode support has been added for
	  domain names.  Running dns.name.from_text() on a Unicode string
	  will now encode each label using the IDN ACE encoding.  The
	  to_unicode() method may be used to convert a dns.name.Name with
	  IDN ACE labels back into a Unicode string.  This functionality
	  requires Python 2.3 or greater.

2005-10-31  Bob Halley  <halley@dnspython.org>

	* (Version 1.3.5 released)

2005-10-12  Bob Halley  <halley@dnspython.org>

	* dns/zone.py: Zone.iterate_rdatasets() and Zone.iterate_rdatas()
	  did not have a default rdtype of dns.rdatatype.ANY as their
	  docstrings said they did.  They do now.

2005-10-06  Bob Halley  <halley@dnspython.org>

	* dns/name.py: Added the parent() method, which returns the
	  parent of a name.

2005-10-01  Bob Halley  <halley@dnspython.org>

	* dns/resolver.py: Added zone_for_name() helper, which returns
	  the name of the zone which contains the specified name.

	* dns/resolver.py: Added get_default_resolver(), which returns
	  the default resolver, initializing it if necessary.

2005-09-29  Bob Halley  <halley@dnspython.org>

	* dns/resolver.py (Resolver._compute_timeout): If time goes
	  backwards a little bit, ignore it.

2005-07-31  Bob Halley  <halley@dnspython.org>

	* (Version 1.3.4 released)

2005-07-31  Bob Halley  <halley@dnspython.org>

	* dns/message.py (make_response): Trying to respond to a response
	  threw a NameError while trying to throw a FormErr since it used
	  the wrong name for the FormErr exception.

	* dns/query.py (_connect): We needed to ignore EALREADY too.

	* dns/query.py: Optional "source" and "source_port" parameters
	  have been added to udp(), tcp(), and xfr().  Thanks to Ralf
	  Weber for suggesting the change and providing a patch.

2005-06-05  Bob Halley  <halley@dnspython.org>

	* dns/query.py: The requirement that the "where" parameter be
	  an IPv4 or IPv6 address is now documented.

2005-06-04  Bob Halley  <halley@dnspython.org>

	* dns/resolver.py: The resolver now does exponential backoff
	  each time it runs through all of the nameservers.

	* dns/resolver.py: rcodes which indicate a nameserver is likely
	  to be a "permanent failure" for a query cause the nameserver
	  to be removed from the mix for that query.

2005-01-30  Bob Halley  <halley@dnspython.org>

	* (Version 1.3.3 released)

2004-10-25  Bob Halley  <halley@dnspython.org>

	* dns/rdtypes/ANY/TXT.py (TXT.from_text): The masterfile parser
	incorrectly rejected TXT records where a value was not quoted.

2004-10-11  Bob Halley  <halley@dnspython.org>

	* dns/message.py: Added make_response(), which creates a skeletal
	response for the specified query.  Added opcode() and set_opcode()
	convenience methods to the Message class.  Added the request_payload
	attribute to the Message class.

2004-10-10  Bob Halley  <halley@dnspython.org>

	* dns/zone.py (from_xfr): dns.zone.from_xfr() in relativization
	mode incorrectly set zone.origin to the empty name.

2004-09-02  Bob Halley  <halley@dnspython.org>

	* dns/name.py (Name.to_wire): The 'file' parameter to
	Name.to_wire() is now optional; if omitted, the wire form will
	be returned as the value of the function.

2004-08-14  Bob Halley  <halley@dnspython.org>

	* dns/message.py (Message.find_rrset): find_rrset() now uses an
	index, vastly improving the from_wire() performance of large
	messages such as zone transfers.

2004-08-07  Bob Halley  <halley@dnspython.org>

	* (Version 1.3.2 released)

2004-08-04  Bob Halley  <halley@dnspython.org>

	* dns/query.py: sending queries to a nameserver via IPv6 now
	works.
	
	* dns/inet.py (af_for_address): Add af_for_address(), which looks
	at a textual-form address and attempts to determine which address
	family it is.

	* dns/query.py: the default for the 'af' parameter of the udp(),
	tcp(), and xfr() functions has been changed from AF_INET to None,
	which causes dns.inet.af_for_address() to be used to determine the
	address family.  If dns.inet.af_for_address() can't figure it out,
	we fall back to AF_INET and hope for the best.

2004-07-31  Bob Halley  <halley@dnspython.org>

	* dns/rdtypes/ANY/NSEC.py (NSEC.from_text): The NSEC text format
	does not allow specifying types by number, so we shouldn't either.

	* dns/renderer.py: the renderer module didn't import random,
	causing an exception to be raised if a query id wasn't provided
	when a Renderer was created.

	* dns/resolver.py (Resolver.query): the resolver wasn't catching
	dns.exception.Timeout, so a timeout erroneously caused the whole
	resolution to fail instead of just going on to the next server.

2004-06-16  Bob Halley  <halley@dnspython.org>

	* dns/rdtypes/ANY/LOC.py (LOC.from_text): LOC milliseconds values
	were converted incorrectly if the length of the milliseconds
	string was less than 3.

2004-06-06  Bob Halley  <halley@dnspython.org>

	* (Version 1.3.1 released)

2004-05-22  Bob Halley  <halley@dnspython.org>

	* dns/update.py (Update.delete): We erroneously specified a
	"deleting" value of dns.rdatatype.NONE instead of
	dns.rdataclass.NONE when the thing being deleted was either an
	Rdataset instance or an Rdata instance.

	* dns/rdtypes/ANY/SSHFP.py: Added support for the proposed SSHFP
	RR type.

2004-05-14  Bob Halley  <halley@dnspython.org>

	* dns/rdata.py (from_text): The masterfile reader did not
	accept the unknown RR syntax when used with a known RR type.

2004-05-08  Bob Halley  <halley@dnspython.org>

	* dns/name.py (from_text): dns.name.from_text() did not raise
	an exception if a backslash escape ended prematurely.

2004-04-09  Bob Halley  <halley@dnspython.org>

	* dns/zone.py (_MasterReader._rr_line): The masterfile reader
	erroneously treated lines starting with leading whitespace but
	not having any RR definition as an error.  It now treats
	them like a blank line (which is not an error).

2004-04-01  Bob Halley  <halley@dnspython.org>
	
	* (Version 1.3.0 released)

2004-03-19  Bob Halley  <halley@dnspython.org>

	* Added support for new DNSSEC types RRSIG, NSEC, and DNSKEY.

2004-01-16  Bob Halley  <halley@dnspython.org>

	* dns/query.py (_connect): Windows returns EWOULDBLOCK instead
	of EINPROGRESS when trying to connect a nonblocking socket.

2003-11-13  Bob Halley  <halley@dnspython.org>

	* dns/rdtypes/ANY/LOC.py (LOC.to_wire): We encoded and decoded LOC
	incorrectly, since we were interpreting the values of altitiude,
	size, hprec, and vprec in meters instead of centimeters.

	* dns/rdtypes/IN/WKS.py (WKS.from_wire): The WKS protocol value is
	encoded with just one octet, not two!

2003-11-09  Bob Halley  <halley@dnspython.org>

	* dns/resolver.py (Cache.maybe_clean): The cleaner deleted items
	from the dictionary while iterating it, causing a RuntimeError
	to be raised.  Thanks to Mark R. Levinson for the bug report,
	regression test, and fix.

2003-11-07  Bob Halley  <halley@dnspython.org>

	* (Version 1.2.0 released)

2003-11-03  Bob Halley  <halley@dnspython.org>

	* dns/zone.py (_MasterReader.read): The saved_state now includes
	the default TTL.

2003-11-01  Bob Halley  <halley@dnspython.org>

	* dns/tokenizer.py (Tokenizer.get): The tokenizer didn't
	handle escaped delimiters.

2003-10-27  Bob Halley  <halley@dnspython.org>

	* dns/resolver.py (Resolver.read_resolv_conf): If no nameservers
	are configured in /etc/resolv.conf, the default nameserver
	list should be ['127.0.0.1'].

2003-09-08  Bob Halley  <halley@dnspython.org>

	* dns/resolver.py (Resolver._config_win32_fromkey): We didn't
	catch WindowsError, which can happen if a key is not defined
	in the registry.

2003-09-06  Bob Halley  <halley@dnspython.org>

	* (Version 1.2.0b1 released)
	
2003-09-05  Bob Halley  <halley@dnspython.org>

	* dns/query.py: Timeout support has been overhauled to provide
	timeouts under Python 2.2 as well as 2.3, and to provide more
	accurate expiration.

2003-08-30  Bob Halley  <halley@dnspython.org>

	* dns/zone.py: dns.exception.SyntaxError is raised for unknown
	master file directives.

2003-08-28  Bob Halley  <halley@dnspython.org>

	* dns/zone.py: $INCLUDE processing is now enabled/disabled using
	the allow_include parameter.  The default is to process $INCLUDE
	for from_file(), and to disallow $INCLUDE for from_text().  The
	master reader now calls zone.check_origin_node() by default after
	the zone has been read.  find_rdataset() called get_node() instead
	of find_node(), which result in an incorrect exception.  The
	relativization state of a zone is now remembered and applied
	consistently when looking up names.  from_xfr() now supports
	relativization like the _MasterReader.

2003-08-22  Bob Halley  <halley@dnspython.org>

	* dns/zone.py: The _MasterReader now understands $INCLUDE.

2003-08-12  Bob Halley  <halley@dnspython.org>

	* dns/zone.py: The _MasterReader now specifies the file and line
	number when a syntax error occurs.  The BIND 8 TTL format is now
	understood when loading a zone, though it will never be emitted.
	The from_file() function didn't pass the zone_factory parameter
	to from_text().

2003-08-10  Bob Halley  <halley@dnspython.org>

	* (Version 1.1.0 released)

2003-08-07  Bob Halley  <halley@dnspython.org>

	* dns/update.py (Update._add): A typo meant that _add would
	fail if the thing being added was an Rdata object (as
	opposed to an Rdataset or the textual form of an Rdata).

2003-08-05  Bob Halley  <halley@dnspython.org>

	* dns/set.py: the simple Set class has been moved to its
	own module, and augmented to support more set operations.

2003-08-04  Bob Halley  <halley@dnspython.org>

	* Node and all rdata types have been "slotted".  This speeds
	things up a little and reduces memory usage noticeably.

2003-08-02  Bob Halley  <halley@dnspython.org>

	* (Version 1.1.0c1 released)

2003-08-02  Bob Halley  <halley@dnspython.org>

	* dns/rdataset.py: SimpleSets now support more set options.
	
	* dns/message.py: Added the get_rrset() method.  from_file() now
	allows Unicode filenames and turns on universal newline support if
	it opens the file itself.

	* dns/node.py: Added the delete_rdataset() and replace_rdataset()
	methods.

	* dns/zone.py: Added the delete_node(), delete_rdataset(), and
	replace_rdataset() methods.  from_file() now allows Unicode
	filenames and turns on universal newline support if it opens the
	file itself.  Added a to_file() method.

2003-08-01  Bob Halley  <halley@dnspython.org>

	* dns/opcode.py: Opcode from/to text converters now understand
	numeric opcodes.  The to_text() method will return a numeric opcode
	string if it doesn't know a text name for the opcode.
	
	* dns/message.py: Added set_rcode().  Fixed code where ednsflags
	wasn't treated as a long.

	* dns/rcode.py: ednsflags wasn't treated as a long.  Rcode from/to
	text converters now understand numeric rcodes.  The to_text()
	method will return a numeric rcode string if it doesn't know
	a text name for the rcode.

	* examples/reverse.py: Added a new example program that builds a
	reverse (address-to-name) mapping table from the name-to-address
	mapping specified by A RRs in zone files.

	* dns/node.py: Added get_rdataset() method.

	* dns/zone.py: Added get_rdataset() and get_rrset() methods.  Added
	iterate_rdatas().

2003-07-31  Bob Halley  <halley@dnspython.org>

	* dns/zone.py: Added the iterate_rdatasets() method which returns
	a generator which yields (name, rdataset) tuples for all the
	rdatasets in the zone matching the specified rdatatype.

2003-07-30  Bob Halley  <halley@dnspython.org>

	* (Version 1.1.0b2 released)

2003-07-30  Bob Halley  <halley@dnspython.org>

	* dns/zone.py: Added find_rrset() and find_rdataset() convenience
	methods.  They let you retrieve rdata with the specified name
	and type in one call.

	* dns/node.py: Nodes no longer have names; owner names are
	associated with nodes in the Zone object's nodes dictionary.

	* dns/zone.py: Zone objects now implement more of the standard
	mapping interface.  __iter__ has been changed to iterate the keys
	rather than values to match the standard mapping interface's
	behavior.

2003-07-20  Bob Halley  <halley@dnspython.org>

	* dns/ipv6.py (inet_ntoa): Handle embedded IPv4 addresses.

2003-07-19  Bob Halley  <halley@dnspython.org>

	* (Version 1.1.0b1 released)

2003-07-18  Bob Halley  <halley@dnspython.org>

	* dns/tsig.py: The TSIG validation of TCP streams where not
	every message is signed now works correctly.

	* dns/zone.py: Zones can now be compared for equality and
	inequality.  If the other object in the comparison is also
	a zone, then "the right thing" happens; i.e. the zones are
	equal iff.: they have the same rdclass, origin, and nodes.

2003-07-17  Bob Halley  <halley@dnspython.org>

	* dns/message.py (Message.use_tsig): The method now allows for
	greater control over the various fields in the generated signature
	(e.g. fudge).
	(_WireReader._get_section): UnknownTSIGKey is now raised if an
	unknown key is encountered, or if a signed message has no keyring.

2003-07-16  Bob Halley  <halley@dnspython.org>

	* dns/tokenizer.py (Tokenizer._get_char): get_char and unget_char
	have been renamed to _get_char and _unget_char since they are not
	useful to clients of the tokenizer.

2003-07-15  Bob Halley  <halley@dnspython.org>

	* dns/zone.py (_MasterReader._rr_line): owner names were being
	unconditionally relativized; it makes much more sense for them
	to be relativized according to the relativization setting of
	the reader.

2003-07-12  Bob Halley  <halley@dnspython.org>

	* dns/resolver.py (Resolver.read_resolv_conf): The resolv.conf
	parser did not allow blank / whitespace-only lines, nor did it
	allow comments.  Both are now supported.

2003-07-11  Bob Halley  <halley@dnspython.org>

	* dns/name.py (Name.to_digestable): to_digestable() now
	requires an origin to be specified if the name is relative.
	It will raise NeedAbsoluteNameOrOrigin if the name is
	relative and there is either no origin or the origin is
	itself relative.
	(Name.split): returned the wrong answer if depth was 0 or depth
	was the length of the name.  split() now does bounds checking
	on depth, and raises ValueError if depth < 0 or depth > the length
	of the name.

2003-07-10  Bob Halley  <halley@dnspython.org>

	* dns/ipv6.py (inet_ntoa): The routine now minimizes its output
	strings.  E.g. the IPv6 address
	"0000:0000:0000:0000:0000:0000:0000:0001" is minimized to "::1".
	We do not, however, make any effort to display embedded IPv4
	addresses in the dot-quad notation.

2003-07-09  Bob Halley  <halley@dnspython.org>

	* dns/inet.py: We now supply our own AF_INET and AF_INET6
	constants since AF_INET6 may not always be available.  If the
	socket module has AF_INET6, we will use it.  If not, we will
	use our own value for the constant.

	* dns/query.py: the functions now take an optional af argument
	specifying the address family to use when creating the socket.

	* dns/rdatatype.py (is_metatype): a typo caused the function
	return true only for type OPT.

	* dns/message.py: message section list elements are now RRsets
	instead of Nodes.  This API change makes processing messages
	easier for many applications.
	
2003-07-07  Bob Halley  <halley@dnspython.org>

	* dns/rrset.py: added.  An RRset is a named rdataset.

	* dns/rdataset.py (Rdataset.__eq__): rdatasets may now be compared
	for equality and inequality with other objects.  Rdataset instance
	variables are now slotted.
	
	* dns/message.py: The wire format and text format readers are now
	classes.  Variables related to reader state have been moved out
	of the message class.

2003-07-06  Bob Halley  <halley@dnspython.org>

	* dns/name.py (from_text): '@' was not interpreted as the empty
	name.

	* dns/zone.py: the master file reader derelativized names in rdata
	relative to the zone's origin, not relative to the current origin.
	The reader now deals with relativization in two steps.  The rdata
	is read and derelativized using the current origin.  The rdata's
	relativity is then chosen using the zone origin and the relativize
	boolean.  Here's an example.

		$ORIGIN foo.example.
		$TTL 300
		bar MX 0 blaz

	If the zone origin is example., and relativization is on, then
	This fragment will become:

		bar.foo.example. 300 IN MX 0 blaz.foo.example.

	after the first step (derelativization to current origin), and

		bar.foo 300 IN MX 0 blaz.foo

	after the second step (relativiation to zone origin).
	
	* dns/namedict.py: added.

	* dns/zone.py: The master file reader has been made into its
	own class.  Reader-related instance variables have been moved
	form the zone class into the reader class.
	
	* dns/zone.py: Add node_factory class attribute.  An application
	can now subclass Zone and Node and have a zone whose nodes are of
	the subclassed Node type.  The from_text(), from_file(), and
	from_xfr() algorithms now take an optional zone_factory argument.
	This allows the algorithms to be used to create zones whose class
	is a subclass of Zone.


2003-07-04  Bob Halley  <halley@dnspython.org>

	* dns/renderer.py: added new wire format rendering module and
	converted message.py to use it.  Applications which want
	fine-grained control over the conversion to wire format may call
	the renderer directy, instead of having it called on their behalf
	by the message code.

2003-07-02  Bob Halley  <halley@dnspython.org>

	* dns/name.py (_validate_labels): The NameTooLong test was
	incorrect.

	* dns/message.py (Message.to_wire): dns.exception.TooBig is
	now raised if the wire encoding exceeds the specified
	maximum size.

2003-07-01  Bob Halley  <halley@dnspython.org>

	* dns/message.py: EDNS encoding was broken.  from_text()
	didn't parse rcodes, flags, or eflags correctly.  Comparing
	messages with other types of objects didn't work.

2003-06-30  Bob Halley  <halley@dnspython.org>

	* (Version 1.0.0 released)

2003-06-30  Bob Halley  <halley@dnspython.org>

	* dns/rdata.py: Rdatas now implement rich comparisons instead of
	__cmp__.

	* dns/name.py: Names now implement rich comparisons instead of
	__cmp__.

	* dns/inet.py (inet_ntop): Always use our code, since the code
	in the socket module doesn't support AF_INET6 conversions if
	IPv6 sockets are not available on the system.

	* dns/resolver.py (Answer.__init__): A dangling CNAME chain was
	not raising NoAnswer.

	* Added a simple resolver Cache class.

	* Added an expiration attribute to answer instances.

2003-06-24  Bob Halley  <halley@dnspython.org>

	* (Version 1.0.0b3 released)

2003-06-24  Bob Halley  <halley@dnspython.org>

	* Renamed module "DNS" to "dns" to avoid conflicting with
	PyDNS.

2003-06-23  Bob Halley  <halley@dnspython.org>

	* The from_text() relativization controls now work the same way as
	the to_text() controls.

	* DNS/rdata.py: The parsing of generic rdata was broken.

2003-06-21  Bob Halley  <halley@dnspython.org>

	* (Version 1.0.0b2 released)

2003-06-21  Bob Halley  <halley@dnspython.org>

	* The Python 2.2 socket.inet_aton() doesn't seem to like
	'255.255.255.255'.  We work around this.

	* Fixed bugs in rdata to_wire() and from_wire() routines of a few
	types.  These bugs were discovered by running the tests/zone.py
	Torture1 test.
	
	* Added implementation of type APL.

2003-06-20  Bob Halley  <halley@dnspython.org>

	* DNS/rdtypes/IN/AAAA.py: Use our own versions of inet_ntop and
	inet_pton if the socket module doesn't provide them for us.

	* The resolver now does a better job handling exceptions.  In
	particular, it no longer eats all exceptions; rather it handles
	those exceptions it understands, and leaves the rest uncaught.
	
	* Exceptions have been pulled into their own module.  Almost all
	exceptions raised by the code are now subclasses of
	DNS.exception.DNSException.  All form errors are subclasses of
	DNS.exception.FormError (which is itself a subclass of
	DNS.exception.DNSException).

2003-06-19  Bob Halley  <halley@dnspython.org>
	
	* Added implementations of types DS, NXT, SIG, and WKS.

	* __cmp__ for type A and AAAA could produce incorrect results.

2003-06-18  Bob Halley  <halley@dnspython.org>

	* Started test suites for zone.py and tokenizer.py.
	
	* Added implementation of type KEY.
	
	* DNS/rdata.py(_base64ify): \n could be emitted erroneously.

	* DNS/rdtypes/ANY/SOA.py (SOA.from_text): The SOA RNAME field could
	be set to the value of MNAME in common cases.

	* DNS/rdtypes/ANY/X25.py: __init__ was broken.

	* DNS/zone.py (from_text): $TTL handling erroneously caused the
	next line to be eaten.

	* DNS/tokenizer.py (Tokenizer.get): parsing was broken for empty
	quoted strings.  Quoted strings didn't handle \ddd escapes.  Such
	escapes are appear not to comply with RFC 1035, but BIND allows
	them and they seem useful, so we allow them too.

	* DNS/rdtypes/ANY/ISDN.py (ISDN.from_text): parsing was
	broken for ISDN RRs without subaddresses.

	* DNS/zone.py (from_file): from_file() didn't work because
	some required parameters were not passed to from_text().

2003-06-17  Bob Halley  <halley@dnspython.org>

	* (Version 1.0.0b1 released)

2003-06-17  Bob Halley  <halley@dnspython.org>

	* Added implementation of type PX.
	
2003-06-16  Bob Halley  <halley@dnspython.org>

	* Added implementation of types CERT, GPOS, LOC, NSAP, NSAP-PTR.

	* DNS/rdatatype.py (_by_value): A cut-and-paste error had broken
	NSAP and NSAP-PTR.

2003-06-12  Bob Halley  <halley@dnspython.org>

	* Created a tests directory and started adding tests.
	
	* Added "and its documentation" to the permission grant in the
	license.

2003-06-12  Bob Halley  <halley@dnspython.org>

	* DNS/name.py (Name.is_wild): is_wild() erroneously raised IndexError
	if the name was empty.

2003-06-10  Bob Halley  <halley@dnspython.org>

	* Added implementations of types AFSDB, X25, and ISDN.
	
	* The documentation associated with the various rdata types has been
	improved.  In particular, instance variables are now described.

2003-06-09  Bob Halley  <halley@dnspython.org>

	* Added implementations of types HINFO, RP, and RT.
	
	* DNS/message.py (make_query): Document that make_query() sets
	flags to DNS.flags.RD, and chooses a random query id.

2003-06-05  Bob Halley  <halley@dnspython.org>

	* (Version 1.0.0a2 released)
	
2003-06-05  Bob Halley  <halley@dnspython.org>
	
	* DNS/node.py: removed __getitem__ and __setitem__, since
	they are not used by the codebase and were not useful in
	general either.

	* DNS/message.py (from_file): from_file() now allows a
	filename to be specified instead of a file object.

	* DNS/rdataset.py: The is_compatible() method of the
	DNS.rdataset.Rdataset class was deleted.

2003-06-04  Bob Halley  <halley@dnspython.org>

	* DNS/name.py (class Name): Names are now immutable.

	* DNS/name.py: the is_comparable() method has been removed, since
	names are always comparable.

	* DNS/resolver.py (Resolver.query): A query could run for up
	to the lifetime + the timeout.  This has been corrected and the
	query will now only run up to the lifetime.

2003-06-03  Bob Halley  <halley@dnspython.org>

	* DNS/resolver.py: removed the 'new' function since it is not the
	style of the library to have such a function.  Call
	DNS.resolver.Resolver() to make a new resolver.

2003-06-03  Bob Halley  <halley@dnspython.org>

	* DNS/resolver.py (Resolver._config_win32_fromkey): The DhcpServer
	list is space separated, not comma separated.

2003-06-03  Bob Halley  <halley@dnspython.org>

	* DNS/update.py: Added an update module to make generating updates
	easier.

2003-06-03  Bob Halley  <halley@dnspython.org>

	* Commas were missing in some of the __all__ entries in various
	__init__.py files.

2003-05-30  Bob Halley  <halley@dnspython.org>

	* (Version 1.0.0a1 released)
