:release-date: 2014-02-03 05:00 P.M UTC

- Now depends on :mod:`amqp` 1.4.2.

- Now always trusts messages of type `application/data` and `application/text`
or which have an unspecified content type (Issue 306).

- Compression errors are now handled as decode errors and will trigger
the ``Consumer.on_decode_error`` callback if specified.

- New ``kombu.Connection.get_heartbeat_interval()`` method that can be
used to access the negotiated heartbeat value.

- `kombu.common.oid_for` no longer uses the MAC address of the host, but
instead uses a process-wide UUID4 as a node id.

This avoids a call to `uuid.getnode()` at module scope.

- Hub.add: Now normalizes registered fileno.

Contributed by Ionel Cristian Mărieș.

- SQS: Fixed bug where the prefetch count limit was not respected.

- Now depends on :mod:`amqp` 1.4.1.

- ``maybe_declare`` now raises a "recoverable connection error" if
the channel is disconnected instead of a :exc:`ChannelError` so that
the operation can be retried.

- Redis: ``Consumer.cancel()`` is now thread safe.

This fixes an issue when using gevent/eventlet and a
message is handled after the consumer is canceled resulting
in a "message for queue without consumers" error.

- Retry operations would not always respect the interval_start
value when calculating the time to sleep for (Issue 303).

Fix contributed by Antoine Legrand.

- Timer: Fixed "unhashable type" error on Python 3.

- Hub: Do not attempt to unregister operations on an already closed
poller instance.

.. _version-3.0.9:

=====
:release-date: 2014-01-13 05:30 P.M UTC
:release-by: Ask Solem

- Now depends on :mod:`amqp` 1.4.0.

- Redis: Basic cancel for fanout based queues now sends a corresponding
``UNSUBSCRIBE`` command to the server.

This fixes an issue with pidbox where reply messages could be received
after the consumer was canceled, giving the ``"message to queue without
consumers"`` error.

- MongoDB: Improved connection string and options handling
(Issue 266 + Issue 120).

Contributed by Alex Koshelev.

- SQS: Limit the number of messages when receiving in batch to 10.

This is a hard limit enforced by Amazon so the sqs transport
must not exceeed this value.

Fix contributed by Eric Reynolds.

- ConsumerMixin: ``consume`` now checks heartbeat every time the
socket times out.

Contributed by Dustin J. Mitchell.

- Retry Policy: A max retries of 0 did not retry forever.

Fix contributed by Antoine Legrand.

- Simple: If passing a Queue object the simple utils will now take
default routing key from that queue.

Contributed by Fernando Jorge Mota.

- ``repr(producer)`` no longer evaluates the underlying channnel.

- Redis: The map of Redis error classes are now exposed at the module level
using the :func:`kombu.transport.redis.get_redis_error_classes` function.

- Async: ``Hub.close`` now sets ``.poller`` to None.

.. _version-3.0.8:

=====
:release-date: 2013-12-16 05:00 P.M UTC
:release-by: Ask Solem

- Serializer: loads and dumps now wraps exceptions raised into
:exc:`~kombu.exceptions.DecodeError` and
:exc:`kombu.exceptions.EncodeError` respectively.

Contributed by Ionel Cristian Maries

- Redis: Would attempt to read from the wrong connection if a select/epoll/kqueue
exception event happened.

Fix contributed by Michael Nelson.

- Redis: Disabling ack emulation now works properly.

Fix contributed by Michael Nelson.

- Redis: :exc:`IOError` and :exc:`OSError` are now treated as recoverable
connection errors.

- SQS: Improved performance by reading messages in bulk.

Contributed by Matt Wise.

- Connection Pool: Attempting to acquire from a closed pool will now
raise :class:`RuntimeError`.

.. _version-3.0.7:

=====
:release-date: 2013-12-02 04:00 P.M UTC
:release-by: Ask Solem

- Fixes Python 2.6 compatibility.

- Redis: Fixes 'bad file descriptor' issue.

.. _version-3.0.6:

=====
:release-date: 2013-11-21 04:50 P.M UTC
:release-by: Ask Solem

- Timer: No longer attempts to hash keyword arguments (Issue 275).

- Async: Did not account for the long type for file descriptors.

Fix contributed by Fabrice Rabaute.

- PyPy: kqueue support was broken.

- Redis: Bad pub/sub payloads no longer crashes the consumer.

- Redis: Unix socket URLs can now specify a virtual host by including
it as a query parameter.

Example URL specifying a virtual host using database number 3:

.. code-block:: text

redis+socket:///tmp/redis.sock?virtual_host=3

- ``kombu.VERSION`` is now a named tuple.
