* Now depends on anyjson 0.3.1

cjson is no longer a recommended json implementation, and anyjson
will now emit a deprecation warning if used.

* Please note that the Pika backend only works with version 0.5.2.

The latest version (0.9.x) drastically changed API, and it is not
compatible yet.

* on_decode_error is now called for exceptions in message_to_python
(Issue 24).

* Redis: did not respect QoS settings.

* Redis: Creating a connection now ensures the connection is established.

This means ``Connection.ensure_connection`` works properly with
Redis.

* consumer_tag argument to ``Queue.consume`` can't be :const:`None`
(Issue 21).

A None value is now automatically converted to empty string.
An empty string will make the server generate a unique tag.

* Connection now supports a ``transport_options`` argument.

This can be used to pass additional arguments to transports.

* Pika: ``drain_events`` raised :exc:`socket.timeout` even if no timeout
set (Issue 8).

.. version-1.0.6:

* The ``delivery_mode`` aliases (persistent/transient) were not automatically
converted to integer, and would cause a crash if using the amqplib
transport.

* Redis: The redis-py :exc:`InvalidData` exception suddenly changed name to
:exc:`DataError`.

* The :envvar:`KOMBU_LOG_DEBUG` environment variable can now be set to log all
channel method calls.

Support for the following environment variables have been added:

* :envvar:`KOMBU_LOG_CHANNEL` will wrap channels in an object that
logs every method call.

* :envvar:`KOMBU_LOG_DEBUG` both enables channel logging and configures the
root logger to emit messages to standard error.

**Example Usage**:

.. code-block:: console

$ KOMBU_LOG_DEBUG=1 python
>>> from kombu import Connection
>>> conn = Connection()
>>> channel = conn.channel()
Start from server, version: 8.0, properties:
{u'product': 'RabbitMQ',.............. }
Open OK! known_hosts []
using channel_id: 1
Channel open
>>> channel.queue_declare('myq', passive=True)
[Kombu channel:1] queue_declare('myq', passive=True)
(u'myq', 0, 1)

.. _version-1.0.5:

=====
:release-date: 2011-03-17 04:00 P.M CET

* Fixed memory leak when creating virtual channels. All virtual transports
affected (redis, mongodb, memory, django, sqlalchemy, couchdb, beanstalk).

* Virtual Transports: Fixed potential race condition when acking messages.

If you have been affected by this, the error would show itself as an
exception raised by the OrderedDict implementation. (``object no longer
exists``).

* MongoDB transport requires the ``findandmodify`` command only available in
MongoDB 1.3+, so now raises an exception if connected to an incompatible
server version.

* Virtual Transports: ``basic.cancel`` should not try to remove unknown
consumer tag.

.. _version-1.0.4:

=====
:release-date: 2011-02-28 04:00 P.M CET
:release-by: Ask Solem

* Added Transport.polling_interval

Used by django-kombu to increase the time to sleep between SELECTs when
there are no messages in the queue.

Users of django-kombu should upgrade to django-kombu v0.9.2.

=====
:release-date: 2011-02-12 04:00 P.M CET

* ConnectionPool: Re-connect if amqplib connection closed

* Adds ``Queue.as_dict`` + ``Exchange.as_dict``.

* Copyright headers updated to include 2011.

.. _version-1.0.2:

=====
:release-date: 2011-01-31 10:45 P.M CET
