- Now depends on :mod:`amqp` 1.4.5.

- RabbitMQ 3.3 changes QoS semantics (Issue 339).

See the RabbitMQ release notes here:
http://www.rabbitmq.com/blog/2014/04/02/breaking-things-with-rabbitmq-3-3/

A new connection property has been added that can be used to detect
whether the remote server is using this new QoS behavior:

.. code-block:: pycon

>>> Connection('amqp://').qos_behavior_matches_spec
False

so if your application depends on the old semantics you can
use this to set the ``apply_global`` flag appropriately:

.. code-block:: python

def update_prefetch_count(channel, new_value):
channel.basic_qos(
0, new_value,
not channel.connection.client.qos_behavior_matches_spec,
)

- Users of :mod:`librabbitmq` is encouraged to upgrade to librabbitmq 1.5.0.

The ``kombu[librabbitmq]`` extra has been updated to depend on this
version.

- Pools: Now takes transport options into account when comparing connections
(Issue 333).

- MongoDB: Fixes Python 3 compatibility.

- Async: select: Ignore socket errors when attempting to unregister handles
from the loop.

- Pidbox: Can now be configured to use a serializer other than json,
but specifying a serializer argument to :class:`~kombu.pidbox.Mailbox`.

Contributed by Dmitry Malinovsky.

- Message decompression now works with Python 3.
