- Redis: Fixes ``TypeError`` problem in ``unregister`` (Issue #342).

Log message:
Update to 3.0.15. From Changelog:

- 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::

        >>> 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::

        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`.
- Message decompression now works with Python 3.

Log message:
Updated to latest release, 3.0.14. From ChangeLog:

- **MongoDB**: Now endures a connection failover (Issue #123).
- **MongoDB**: Fixed ``KeyError`` when a replica set member is removed.
    Also fixes celery#971 and celery/#898.
- **MongoDB**: Fixed MongoDB broadcast cursor re-initialization bug.
- **Async**: Fixed bug in lax semaphore implementation where in
  some usage patterns the limit was not honored correctly.
- **Redis**: Fixed problem with fanout when using Python 3 (Issue #324).
- **Redis**: Fixed ``AttributeError`` from attempting to close a non-existing
  connection (Issue #320).
- Redis: Fixed serious race condition that could lead to data loss.

    The delivery tags were accidentally set to be an incremental number
    local to the channel, but the delivery tags need to be globally
    unique so that a message can not overwrite an older message
    in the backup store.

    This change is not backwards incompatible and you are encouraged
    to update all your system using a previous version as soon as possible.

- Now depends on :mod:`amqp` 1.4.4.
- Pidbox: Now makes sure message encoding errors are handled by default,
  so that a custom error handler does not need to be specified.
- Redis: The fanout exchange can now use AMQP patterns to route and filter
  messages.
    This change is backwards incompatible and must be enabled with
    the ``fanout_patterns`` transport option::

        >>> conn = kombu.Connection('redis://', transport_options={
        ...     'fanout_patterns': True,
        ... })

    When enabled the exchange will work like an amqp topic exchange
    if the binding key is a pattern.

    This is planned to be default behavior in the future.

- Redis: Fixed ``cycle`` no such attribute error.

Log message:
Updated to latest release, 3.0.12. From Changelog:

3.0.12
======

- Now depends on :mod:`amqp` 1.4.3.
- Fixes Python 3.4 logging incompatibility (Issue #311).
- Redis: Now properly handles unknown pub/sub messages.
- amqplib: Fixed bug where more bytes were requested from the socket
  than necessary.

3.0.11
======

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

Log message:
Updated to latest release, 3.0.10. Now depends on net/py-amqp>=1.4.1. From
Changelog:

3.0.10
======

- 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 cancelled 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).
- Timer: Fixed "unhashable type" error on Python 3.
- Hub: Do not attempt to unregister operations on an already closed
  poller instance.

3.0.9
=====

- 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 cancelled, giving the ``"message to queue without
    consumers"`` error.
- MongoDB: Improved connection string and options handling
  (Issue #266 + Issue #120).
- 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.
- ConsumerMixin: ``consume`` now checks heartbeat every time the
  socket times out.
- Retry Policy: A max retries of 0 did not retry forever.
- Simple: If passing a Queue object the simple utils will now take
  default routing key from that queue.
- ``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.
