+2010-01-13 Bob Halley <halley@dnspython.org>
+
+ * dns/dnssec.py: Added RSASHA256 and RSASHA512 codepoints; added
+ other missing codepoints to _algorithm_by_text.
+
+2010-01-12 Bob Halley <halley@dnspython.org>
+
+ * Escapes in masterfiles now work correctly. Previously they were
+ only working correctly when the text involved was part of a domain
+ name.
+
+ * dns/tokenizer.py: The tokenizer's get() method now returns Token
+ objects, not (type, text) tuples.
+
+2009-11-13 Bob Halley <halley@dnspython.org>
+
+ * Support has been added for hmac-sha1, hmac-sha224, hmac-sha256,
+ hmac-sha384 and hmac-sha512. Thanks to Kevin Chen for a
+ thoughtful, high quality patch.
+
+ * dns/update.py (Update::present): A zero TTL was not added if
+ present() was called with a single rdata, causing _add() to be
+ unhappy. Thanks to Eugene Kim for reporting the problem and
+ submitting a patch.
+
+ * dns/entropy.py: Use os.urandom() if present. Don't seed until
+ someone wants randomness.
+
+2009-09-16 Bob Halley <halley@dnspython.org>
+
+ * dns/entropy.py: The entropy module needs locking in order to be
+ used safely in a multithreaded environment. Thanks to Beda Kosata
+ for reporting the problem.
+
+2009-07-27 Bob Halley <halley@dnspython.org>
+
+ * dns/query.py (xfr): The socket was not set to nonblocking mode.
+ Thanks to Erik Romijn for reporting this problem.
+
+2009-07-23 Bob Halley <halley@dnspython.org>
+
+ * dns/rdtypes/IN/SRV.py (SRV._cmp): SRV records were compared
+ incorrectly due to a cut-and-paste error. Thanks to Tommie
+ Gannert for reporting this bug.
+
+ * dns/e164.py (query): The resolver parameter was not used.
+ Thanks to Matías Bellone for reporting this bug.
+
+2009-06-23 Bob Halley <halley@dnspython.org>
+
+ * dns/entropy.py (EntropyPool.__init__): open /dev/random unbuffered;
+ there's no need to consume more randomness than we need. Thanks
+ to Brian Wellington for the patch.
+
+2009-06-19 Bob Halley <halley@dnspython.org>
+
+ * (Version 1.7.1 released)
+
+2009-06-19 Bob Halley <halley@dnspython.org>
+
+ * DLV.py was omitted from the kit
+
+ * Negative prerequisites were not handled correctly in _get_section().
+
+2009-06-19 Bob Halley <halley@dnspython.org>
+
+ * (Version 1.7.0 released)
+
+2009-06-19 Bob Halley <halley@dnspython.org>
+
+ * On Windows, the resolver set the domain incorrectly. Thanks
+ to Brandon Carpenter for reporting this bug.
+
+ * Added a to_digestable() method to rdata classes; it returns the
+ digestable form (i.e. DNSSEC canonical form) of the rdata. For
+ most rdata types this is the same uncompressed wire form. For
+ certain older DNS RR types, however, domain names in the rdata
+ are downcased.
+
+ * Added support for the HIP RR type.
+
+2009-06-18 Bob Halley <halley@dnspython.org>
+
+ * Added support for the DLV RR type.
+
+ * Added various DNSSEC related constants (e.g. algorithm identifiers,
+ flag values).
+
+ * dns/tsig.py: Added support for BADTRUNC result code.
+
+ * dns/query.py (udp): When checking that addresses are the same,
+ use the binary form of the address in the comparison. This
+ ensures that we don't treat addresses as different if they have
+ equivalent but differing textual representations. E.g. "1:00::1"
+ and "1::1" represent the same address but are not textually equal.
+ Thanks to Kim Davies for reporting this bug.
+
+ * The resolver's query() method now has an optional 'source' parameter,
+ allowing the source IP address to be specified. Thanks to
+ Alexander Lind for suggesting the change and sending a patch.
+
+ * Added NSEC3 and NSEC3PARAM support.
+
+2009-06-17 Bob Halley <halley@dnspython.org>
+
+ * Fixed NSEC.to_text(), which was only printing the last window.
+ Thanks to Brian Wellington for finding the problem and fixing it.
+
+2009-03-30 Bob Halley <halley@dnspython.org>
+
+ * dns/query.py (xfr): Allow UDP IXFRs. Use "one_rr_per_rrset" mode when
+ doing IXFR.
+
+2009-03-30 Bob Halley <halley@dnspython.org>
+
+ * Add "one_rr_per_rrset" mode switch to methods which parse
+ messages from wire format (e.g. dns.message.from_wire(),
+ dns.query.udp(), dns.query.tcp()). If set, each RR read is
+ placed in its own RRset (instead of being coalesced).
+
+2009-03-30 Bob Halley <halley@dnspython.org>
+
+ * Added EDNS option support.
+
+2008-10-16 Bob Halley <halley@dnspython.org>
+
+ * dns/rdtypes/ANY/DS.py: The from_text() parser for DS RRs did not
+ allow multiple Base64 chunks. Thanks to Rakesh Banka for
+ finding this bug and submitting a patch.
+
+2008-10-08 Bob Halley <halley@dnspython.org>
+
+ * Add entropy module.
+
+ * When validating TSIGs, we need to use the absolute name.
+
+2008-06-03 Bob Halley <halley@dnspython.org>
+
+ * dns/message.py (Message.set_rcode): The mask used preserved the
+ extended rcode, instead of everything else in ednsflags.
+
+ * dns/message.py (Message.use_edns): ednsflags was not kept
+ coherent with the specified edns version.
+
+2008-02-06 Bob Halley <halley@dnspython.org>
+
+ * dns/ipv6.py (inet_aton): We could raise an exception other than
+ dns.exception.SyntaxError in some cases.
+
+ * dns/tsig.py: Raise an exception when the peer has set a non-zero
+ TSIG error.
+
+2007-11-25 Bob Halley <halley@dnspython.org>
+
+ * (Version 1.6.0 released)
+
+2007-11-25 Bob Halley <halley@dnspython.org>
+
+ * dns/query.py (_wait_for): if select() raises an exception due to
+ EINTR, we should just select() again.
+
+2007-06-13 Bob Halley <halley@dnspython.org>
+
+ * dns/inet.py: Added is_multicast().
+
+ * dns/query.py (udp): If the queried address is a multicast address, then
+ don't check that the address of the response is the same as the address
+ queried.
+
+2007-05-24 Bob Halley <halley@dnspython.org>
+
+ * dns/rdtypes/IN/NAPTR.py: NAPTR comparisons didn't compare the
+ preference field due to a typo.
+
+2007-02-07 Bob Halley <halley@dnspython.org>
+
+ * dns/resolver.py: Integrate code submitted by Paul Marks to
+ determine whether a Windows NIC is enabled. The way dnspython
+ used to do this does not work on Windows Vista.
+
+2006-12-10 Bob Halley <halley@dnspython.org>
+
+ * (Version 1.5.0 released)
+
+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>

+
+INTRODUCTION
+
+dnspython is a DNS toolkit for Python. It supports almost all record
+types. It can be used for queries, zone transfers, and dynamic
+updates. It supports TSIG authenticated messages and EDNS0.
+
+dnspython provides both high and low level access to DNS. The high
+level classes perform queries for data of a given name, type, and
+class, and return an answer set. The low level classes allow direct
+manipulation of DNS zones, messages, names, and records.
+
+To see a few of the ways dnspython can be used, look in the examples/
+directory.
+
+dnspython originated at Nominum where it was developed to facilitate
+the testing of DNS software. Nominum has generously allowed it to be
+open sourced under a BSD-style license, and helps support its future
+development by continuing to employ the author :).
+
+
+ABOUT THIS RELEASE
+
+This is dnspython 1.8.0
+
+New since 1.7.1:
+
+ Support for hmac-sha1, hmac-sha224, hmac-sha256, hmac-sha384
+ and hmac-sha512 has been contributed by Kevin Chen.
+
+ The tokenizer's tokens are now Token objects instead of (type,
+ value) tuples.
+
+Bugs fixed since 1.7.1:
+
+ Escapes in masterfiles now work correctly. Previously they
+ were only working correctly when the text involved was part of
+ a domain name.
+
+ When constructing a DDNS update, if the present() method was
+ used with a single rdata, a zero TTL was not added.
+
+ The entropy pool needed locking to be thread safe.
+
+ The entropy pool's reading of /dev/random could cause
+ dnspython to block.
+
+ The entropy pool did buffered reads, potentially consuming more
+ randomness than we needed.
+
+ The entropy pool did not seed with high quality randomness on
+ Windows.
+
+ SRV records were compared incorrectly.
+
+ In the e164 query function, the resolver parameter was not
+ used.
+
+New since 1.7.0:
+
+ Nothing
+
+Bugs fixed since 1.7.0:
+
+ The 1.7.0 kitting process inadventently omitted the code for the
+ DLV RR.
+
+ Negative DDNS prerequisites are now handled correctly.
+
+New since 1.6.0:
+
+ Rdatas now have a to_digestable() method, which returns the
+ DNSSEC canonical form of the rdata, suitable for use in
+ signature computations.
+
+ The NSEC3, NSEC3PARAM, DLV, and HIP RR types are now supported.
+
+ An entropy module has been added and is used to randomize query ids.
+
+ EDNS0 options are now supported.
+
+ UDP IXFR is now supported.
+
+ The wire format parser now has a 'one_rr_per_rrset' mode, which
+ suppresses the usual coalescing of all RRs of a given type into a
+ single RRset.
+
+ Various helpful DNSSEC-related constants are now defined.
+
+ The resolver's query() method now has an optional 'source' parameter,
+ allowing the source IP address to be specified.
+
+Bugs fixed since 1.6.0:
+
+ On Windows, the resolver set the domain incorrectly.
+
+ DS RR parsing only allowed one Base64 chunk.
+
+ TSIG validation didn't always use absolute names.
+
+ NSEC.to_text() only printed the last window.
+
+ We did not canonicalize IPv6 addresses before comparing them; we
+ would thus treat equivalent but different textual forms, e.g.
+ "1:00::1" and "1::1" as being non-equivalent.
+
+ If the peer set a TSIG error, we didn't raise an exception.
+
+ Some EDNS bugs in the message code have been fixed (see the ChangeLog
+ for details).
+
+New since 1.5.0:
+ Added dns.inet.is_multicast().
+
+Bugs fixed since 1.5.0:
+
+ If select() raises an exception due to EINTR, we should just
+ select() again.
+
+ If the queried address is a multicast address, then don't
+ check that the address of the response is the same as the
+ address queried.
+
+ NAPTR comparisons didn't compare the preference field due to a
+ typo.
+
+ Testing of whether a Windows NIC is enabled now works on Vista
+ thanks to code contributed by Paul Marks.
+
+New since 1.4.0:
+
+ Answer objects now support more of the python sequence
+ protocol, forwarding the requests to the answer 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]".
+
+ Making requests using EDNS, including indicating DNSSEC awareness,
+ is now easier. For example, you can now say:
+
+ q = dns.message.make_query('www.dnspython.org', 'MX',
+ want_dnssec=True)
+
+ dns.query.xfr() can now be used for IXFR.
+
+ Support has been added for the DHCID, IPSECKEY, and SPF RR types.
+
+ UDP messages from unexpected sources can now be ignored by
+ setting ignore_unexpected to True when calling dns.query.udp.
+
+Bugs fixed since 1.4.0:
+
+ If /etc/resolv.conf didn't exist, we raised an exception
+ instead of simply using the default resolver configuration.
+
+ In dns.resolver.Resolver._config_win32_fromkey(), we were
+ passing the wrong variable to self._config_win32_search().
+
+New since 1.3.5:
+
+ You can now convert E.164 numbers to/from their ENUM name
+ forms:
+
+ >>> import dns.e164
+ >>> n = dns.e164.from_e164("+1 555 1212")
+ >>> n
+ <DNS name 2.1.2.1.5.5.5.1.e164.arpa.>
+ >>> dns.e164.to_e164(n)
+ '+15551212'
+
+ You can now convert IPv4 and IPv6 address to/from their
+ corresponding DNS reverse map names:
+
+ >>> import dns.reversename
+ >>> n = dns.reversename.from_address("127.0.0.1")
+ >>> n
+ <DNS name 1.0.0.127.in-addr.arpa.>
+ >>> dns.reversename.to_address(n)
+ '127.0.0.1'
+
+ You can now convert between Unicode strings and their IDN ACE
+ form:
+
+ >>> n = dns.name.from_text(u'les-\u00e9l\u00e8ves.example.')
+ >>> n
+ <DNS name xn--les-lves-50ai.example.>
+ >>> n.to_unicode()
+ u'les-\xe9l\xe8ves.example.'
+
+ The origin parameter to dns.zone.from_text() and dns.zone.to_text()
+ is now optional. If not specified, the origin will be taken from
+ the first $ORIGIN statement in the master file.
+
+ Sanity checking of a zone can be disabled; this is useful when
+ working with files which are zone fragments.
+
+Bugs fixed since 1.3.5:
+
+ The correct delimiter was not used when retrieving the
+ list of nameservers from the registry in certain versions of
+ windows.
+
+ The floating-point version of latitude and longitude in LOC RRs
+ (float_latitude and float_longitude) had incorrect signs for
+ south latitudes and west longitudes.
+
+ BIND 8 TTL syntax is now accepted in all TTL-like places (i.e.
+ SOA fields refresh, retry, expire, and minimum; SIG/RRSIG
+ field original_ttl).
+
+ TTLs are now bounds checked when their text form is parsed,
+ and their values must be in the closed interval [0, 2^31 - 1].
+
+New since 1.3.4:
+
+ In the resolver, if time goes backward a little bit, ignore
+ it.
+
+ zone_for_name() has been added to the resolver module. It
+ returns the zone which is authoritative for the specified
+ name, which is handy for dynamic update. E.g.
+
+ import dns.resolver
+ print dns.resolver.zone_for_name('www.dnspython.org')
+
+ will output "dnspython.org." and
+
+ print dns.resolver.zone_for_name('a.b.c.d.e.f.example.')
+
+ will output ".".
+
+ The default resolver can be fetched with the
+ get_default_resolver() method.
+
+ You can now get the parent (immediate superdomain) of a name
+ by using the parent() method.
+
+ Zone.iterate_rdatasets() and Zone.iterate_rdatas() now have
+ a default rdtype of dns.rdatatype.ANY like the documentation
+ says.
+
+ A Dynamic DNS example, ddns.py, has been added.
+
+New since 1.3.3:
+
+ The source address and port may now be specified when calling
+ dns.query.{udp,tcp,xfr}.
+
+ The resolver now does exponential backoff each time it runs
+ through all of the nameservers.
+
+ 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.
+
+New since 1.3.2:
+
+ dns.message.Message.find_rrset() now uses an index, vastly
+ improving the from_wire() performance of large messages such
+ as zone transfers.
+
+ Added dns.message.make_response(), which creates a skeletal
+ response for the specified query.
+
+ Added opcode() and set_opcode() convenience methods to the
+ dns.message.Message class. Added the request_payload
+ attribute to the Message class.
+
+ The 'file' parameter of dns.name.Name.to_wire() is now
+ optional; if omitted, the wire form will be returned as the
+ value of the function.
+
+ dns.zone.from_xfr() in relativization mode incorrectly set
+ zone.origin to the empty name.
+
+ The masterfile parser incorrectly rejected TXT records where a
+ value was not quoted.
+
+New since 1.3.1:
+
+ The NSEC format doesn't allow specifying types by number, so
+ we shouldn't either. (Using the unknown type format is still
+ OK though.)
+
+ 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.
+
+ 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.
+
+ The conversion of LOC milliseconds values from text to binary was
+ incorrect if the length of the milliseconds string was not 3.
+
+New since 1.3.0:
+
+ Added support for the SSHFP type.
+
+New since 1.2.0:
+
+ Added support for new DNSSEC types RRSIG, NSEC, and DNSKEY.
+
+This release fixes all known bugs.
+
+See the ChangeLog file for more detailed information on changes since
+the prior release.

+Tutorial documentation
+
+More examples
+
+It would be nice to have a tokenizer that used regular expressions
+because it would be faster.
+
+Teach the resolver about DNAME (right now it relies on the server adding
+synthesized CNAMEs)
+
+Add TKEY support.
+
+TSIG works, but needs cleaning up -- probably better encapsulation of
+TSIG state to make things much simpler and easier to use.
