- Pidbox: Now warns if there are multiple nodes consuming from
the same pidbox.

- Adds :attr:`Queue.on_declared <kombu.Queue.on_declared>`

A callback to be called when the queue is declared,
with signature ``(name, messages, consumers)``.

- Now uses fuzzy matching to suggest alternatives to typos in transport
names.

- SQS: Adds new transport option ``queue_prefix``.

Contributed by j0hnsmith.

- pyamqp: No longer overrides verify_connection.

- SQS: Now specifies the ``driver_type`` and ``driver_name``
attributes.

Fix contributed by Mher Movsisyan.

- Fixed bug with ``kombu.utils.retry_over_time`` when no errback
specified.


.. _version-2.5.8:

=====
:release-date: 2013-03-21 04:00 P.M UTC
:release-by: Ask Solem

- Now depends on :mod:`amqp` 1.0.10 which fixes a Python 3 compatibility error.

- Redis: Fixed a possible race condition (Issue 171).

- Redis: Ack emulation/visibility_timeout can now be disabled
using a transport option.

Ack emulation adds quite a lot of overhead to ensure data is safe
even in the event of an unclean shutdown. If data loss do not worry
you there is now an `ack_emulation` transport option you can use
to disable it:

.. code-block:: python

Connection('redis://', transport_options={'ack_emulation': False})

- SQS: Fixed :mod:`boto` v2.7 compatibility (Issue 207).

- Exchange: Should not try to re-declare default exchange (``""``)
(Issue 209).

- SQS: Long polling is now disabled by default as it was not
implemented correctly, resulting in long delays between receiving
messages (Issue 202).

- Fixed Python 2.6 incompatibility depending on ``exc.errno``
being available.

Fix contributed by Ephemera.

.. _version-2.5.7:

=====
:release-date: 2013-03-08 01:00 P.M UTC
:release-by: Ask Solem

- Now depends on amqp 1.0.9

- Redis: A regression in 2.5.6 caused the redis transport to
ignore options set in ``transport_options``.

- Redis: New ``socket_timeout`` transport option.

- Redis: ``InconsistencyError`` is now regarded as a recoverable error.

- Resource pools: Will no longer attempt to release resource
that was never acquired.

- MongoDB: Now supports the ``ssl`` option.

.. _version-2.5.6:

=====
:release-date: 2013-02-08 01:00 P.M UTC
:release-by: Ask Solem

- Now depends on amqp 1.0.8 which works around a bug found on some
Python 2.5 installations where 2**32 overflows to 0.

.. _version-2.5.5:

=====
:release-date: 2013-02-07 05:00 P.M UTC
:release-by: Ask Solem

SQS: Now supports long polling (Issue 176).

The polling interval default has been changed to 0 and a new
transport option (``wait_time_seconds``) has been added.
This parameter specifies how long to wait for a message from
SQS, and defaults to 20 seconds, which is the maximum
value currently allowed by Amazon SQS.

- SQS: Now removes unpickleable fields before restoring messages.

- Consumer.__exit__ now ignores exceptions occurring while
canceling the consumer.

- Virtual: Routing keys can now consist of characters also used
in regular expressions (e.g. parens) (Issue 194).

- Virtual: Fixed compression header when restoring messages.

Fix contributed by Alex Koshelev.

- Virtual: ack/reject/requeue now works while using ``basic_get``.

- Virtual: Message.reject is now supported by virtual transports
(requeue depends on individual transport support).

- Fixed typo in hack used for static analyzers.

Fix contributed by Basil Mironenko.
