=================================

Deprecations and Removals
-------------------------
 - The `protocol` attribute of twisted.names.client.Resolver,
   deprecated since Twisted 8.2, has been removed. (#6045)
 - twisted.names.hosts.Resolver is no longer a
   `twisted.persisted.styles.Versioned` subclass. (#6092)

Other
-----
 - #5594, #6056, #6057, #6058, #6059, #6093


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)

=================================

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)
=================================

--------
 - twisted.names.dns.Message now uses a specially constructed
   dictionary for looking up record types.  This yields a significant
   performance improvement on PyPy. (#4283)
