http://twistedmatrix.com/trac/ticket/<number>
Twisted Names 12.2.0 (2012-08-26)
=================================
Features
--------
- twisted.names.srvconnect.SRVConnector now takes a default port to
use when SRV lookup fails. (#3456)
Other
-----
- #5647
Twisted Names 12.1.0 (2012-06-02)
=================================
Features
--------
- "twistd dns" secondary server functionality and
twisted.names.secondary now support retrieving zone information
from a master running on a non-standard DNS port. (#5468)
Bugfixes
--------
- twisted.names.dns.DNSProtocol instances no longer throw an
exception when disconnecting. (#5471)
- twisted.names.tap.makeService (thus also "twistd dns") now makes a
DNS server which gives precedence to the hosts file from its
configuration over the remote DNS servers from its configuration.
(#5524)
- twisted.name.cache.CacheResolver now makes sure TTLs on returned
results are never negative. (#5579)
- twisted.names.cache.CacheResolver entries added via the initializer
are now timed out correctly. (#5638)
Improved Documentation
----------------------
- The examples now contain instructions on how to run them and
descriptions in the examples index. (#5588)
Deprecations and Removals
-------------------------
- The deprecated twisted.names.dns.Record_mx.exchange attribute was
removed. (#4549)
Twisted Names 12.0.0 (2012-02-10)
=================================
Bugfixes
--------
- twisted.names.dns.Message now sets the `auth` flag on RRHeader
instances it creates to reflect the authority of the message
itself. (#5421)
Twisted Names 11.1.0 (2011-11-15)
=================================
Features
--------
- twisted.names.dns.Message now parses records of unknown type into
instances of a new `UnknownType` class. (#4603)
Bugfixes
--------
- twisted.names.dns.Name now detects loops in names it is decoding
and raises an exception. Previously it would follow the loop
forever, allowing a remote denial of service attack against any
twisted.names client or server. (#5064)
- twisted.names.hosts.Resolver now supports IPv6 addresses; its
lookupAddress method now filters them out and its lookupIPV6Address
method is now implemented. (#5098)
Twisted Names 11.0.0 (2011-04-01)
=================================
No significant changes have been made for this release.
Twisted Names 10.2.0 (2010-11-29)
=================================
Features
--------
- twisted.names.server can now serve SPF resource records using
twisted.names.dns.Record_SPF. twisted.names.client can query for
them using lookupSenderPolicy. (#3928)
Bugfixes
--------
- twisted.names.common.extractRecords doesn't try to close the
transport anymore in case of recursion, as it's done by the
Resolver itself now. (#3998)
Improved Documentation
----------------------
- Tidied up the Twisted Names documentation for easier conversion.
(#4573)
Twisted Names 10.1.0 (2010-06-27)
=================================
Features
--------
- twisted.names.dns.Message now uses a specially constructed
dictionary for looking up record types. This yields a significant
performance improvement on PyPy. (#4283)
Twisted Names 10.0.0 (2010-03-01)
=================================
Bugfixes
--------
- twisted.names.root.Resolver no longer leaks UDP sockets while
resolving names. (#970)
Deprecations and Removals
-------------------------
- Several top-level functions in twisted.names.root are now
deprecated. (#970)
Other
-----
- #4066
Twisted Names 9.0.0 (2009-11-24)
================================
Deprecations and Removals
-------------------------
- client.ThreadedResolver is deprecated in favor of
twisted.internet.base.ThreadedResolver (#3710)
Other
-----
- #3540, #3560, #3712, #3750, #3990
Names 8.2.0 (2008-12-16)
========================
Features
--------
- The NAPTR record type is now supported (#2276)
Fixes
-----
- Make client.Resolver less vulnerable to the Birthday Paradox attack by
avoiding sending duplicate queries when it's not necessary (#3347)
- client.Resolver now uses a random source port for each DNS request (#3342)
- client.Resolver now uses a full 16 bits of randomness for message IDs,
instead of 10 which it previously used (#3342)
- All record types now have value-based equality and a string representation
(#2935)
Other
-----
- #1622, #3424
8.1.0 (2008-05-18)
==================
Fixes
-----
- The deprecated mktap API is no longer used (#3127)
8.0.0 (2008-03-17)
==================
Fixes
-----
- Refactor DNSDatagramProtocol and DNSProtocol to use same base class (#2414)
- Change Resolver to query specified nameservers in specified order, instead
of reverse order. (#2290)
- Make SRVConnector work with bad results and NXDOMAIN responses.
(#1908, #2777)
- Handle write errors happening in dns queries, to have correct deferred
failures. (#2492)
- Fix the value of OP_NOTIFY and add a definition for OP_UPDATE. (#2945)
Misc
----
- #2685, #2936, #2581, #2847
0.4.0 (2007-01-06)
==================
Features
--------
- In the twisted.names client, DNS responses which represent errors
are now translated to informative exception objects, rather than
empty lists. This means that client requests which fail will now
errback their Deferreds (#2248)
Fixes
-----
- A major DoS vulnerability in the UDP DNS server was fixed (#1708)
Misc
----
