it would always connect to localhost (default setting) no matter what
connection parameters were provided (Issue 176).

.. _version-2.4.9:

=====
:release-date: 2012-11-21 03:00 P.M UTC
:release-by: Ask Solem

- Redis: Fixed race condition that could occur while trying to restore
messages (Issue 171).

Fix contributed by Ollie Walsh.

- Redis: Each channel is now using a specific connection pool instance,
which is disconnected on connection failure.

- ProducerPool: Fixed possible dead-lock in the acquire method.

- ProducerPool: ``force_close_all`` no longer tries to call the non-existent
``Producer._close``.

- librabbitmq: Now implements ``transport.verify_connection`` so that
connection pools will not give back connections that are no longer working.

- New and better ``repr()`` for Queue and Exchange objects.

- Python 3: Fixed problem with running the unit test suite.

- Python 3: Fixed problem with JSON codec.

.. _version-2.4.8:

=====
:release-date: 2012-11-02 05:00 P.M UTC
:release-by: Ask Solem

- Redis: Improved fair queue cycle implementation (Issue 166).

Contributed by Kevin McCarthy.

- Redis: Unacked message restore limit is now unlimited by default.

Also, the limit can now be configured using the ``unacked_restore_limit``
transport option:

.. code-block:: python

Connection('redis://', transport_options={
'unacked_restore_limit': 100,
})

A limit of 100 means that the consumer will restore at most 100
messages at each pass.

- Redis: Now uses a mutex to ensure only one consumer restores messages at a
time.

The mutex expires after 5 minutes by default, but can be configured
using the ``unacked_mutex_expire`` transport option.

- LamportClock.adjust now returns the new clock value.

- Heartbeats can now be specified in URLs.

Fix contributed by Mher Movsisyan.

- Kombu can now be used with PyDev, PyCharm and other static analysis tools.

- Fixes problem with msgpack on Python 3 (Issue 162).

Fix contributed by Jasper Bryant-Greene

- amqplib: Fixed bug with timeouts when SSL is used in non-blocking mode.

.. _version-2.4.7:

=====
:release-date: 2012-09-18 03:00 P.M BST
:release-by: Ask Solem

- Virtual: Unknown exchanges now default to 'direct' when sending a message.

- MongoDB: Fixed memory leak when merging keys stored in the db (Issue 159)

Fix contributed by Michael Korbakov.

- MongoDB: Better index for MongoDB transport (Issue 158).

This improvement will create a new compund index for queue and _id in order
to be able to use both indexed fields for getting a new message (using
queue field) and sorting by _id. It'll be necessary to manually delete
the old index from the collection.
