5.6.0

=====
:release-date: 1 November, 2025
:release-by: Tomer Nosrati

Key Highlights
~~~~~~~~~~~~~~

QoS Max Prefetch Limit
----------------------

`PR 2348 <https://github.com/celery/kombu/pull/2348>`_

Prevent Out Of Memory crashes when queues flood with ETA/countdown tasks. The new optional ``max_prefetch`` parameter caps how many messages workers hold in memory. Defaults to unlimited (``None``) to preserve existing behavior.

.. code-block:: python

 from kombu.common import QoS

  Limit prefetch to maximum 100 messages
 qos = QoS(callback=consumer.qos, initial_value=10, max_prefetch=100)

Redis Polling Interval Support
------------------------------

`PR 2346 <https://github.com/celery/kombu/pull/2346>`_

Fix Redis transport to properly propagate ``polling_interval`` and ``brpop_timeout`` from ``transport_options`` to the Channel's ``_brpop_start`` timeout.

.. code-block:: python

 app.conf.broker_transport_options = {"polling_interval": 10}

Leave it unset to keep the familiar 1-second default, or raise it to slow down idle polling.

Pidbox RabbitMQ 4.x Compatibility
---------------------------------

`PR 2338 <https://github.com/celery/kombu/pull/2338>`_

Let pidbox queues work on RabbitMQ 4.x brokers that reject transient, non-exclusive queues.

MongoDB Transport Improvements
------------------------------

`PR 2347 <https://github.com/celery/kombu/pull/2347>`_

URI options now come through lowercase and flattened again, so settings like ``replicaSet=test_rs`` show up as ``options['replicaset']``.

Resource Pool Gevent Compatibility
----------------------------------

`PR 2314 <https://github.com/celery/kombu/pull/2314>`_

Restore compatibility with recent gevent releases that monkey-patch the standard library queue.

Timezone-aware UTC Timestamps
-----------------------------

`PR 2355 <https://github.com/celery/kombu/pull/2355>`_

Replace every usage of ``datetime.utcnow()`` with ``datetime.now(timezone.utc)`` to return timezone-aware UTC datetimes.

Redis Client Name Support
----------------------------------

`PR 2367 <https://github.com/celery/kombu/pull/2367>`_

Support for propagating the ``client_name`` connection parameter through the Redis transport (including Sentinel) so that connections appear with meaningful names in monitoring tools.
