dnspython 1.2.0b1 has been released.

Here's the README:



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/

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 :).


This is dnspython 1.2.0b1.

New since 1.1.0:

	Timeout support has been overhauled.  It now works on Python
	2.2 as well as 2.3, and the total time spent processing a
	query is now much more controllable before since the timeout
	is now on the whole query instead of just on individual
	network calls.

	The master file reader now gives the filename and line number
	of the offending input when a syntax error occurs.

	$INCLUDE is now supported in DNS master files.  Processing
	of $INCLUDE can also be disabled if desired.

	BIND 8 style TTLs, e.g. "1w2d3h4m5s", are accepted when reading
	a master file, but will never be emitted.

	Basic zone sanity checks are made after a zone is loaded.
	Specifically, the zone must have SOA and NS rdatasets at its

This release fixes all known bugs.

the prior release.
