This document contains change notes for bugfix & new features
in the & 5.1.x series, please see :ref:`whatsnew-5.1` for
an overview of what's new in Celery 5.1.

.. version-5.1.2:

5.1.2
=====
:release-date: 2021-06-28 16.15 P.M UTC+3:00
:release-by: Omer Katz

- When chords fail, correctly call errbacks. (#6814)

    We had a special case for calling errbacks when a chord failed which
    assumed they were old style. This change ensures that we call the proper
    errback dispatch method which understands new and old style errbacks,
    and adds test to confirm that things behave as one might expect now.
- Avoid using the ``Event.isSet()`` deprecated alias. (#6824)
- Reintroduce sys.argv default behaviour for ``Celery.start()``. (#6825)

.. version-5.1.1:

- Fix ``--pool=threads`` support in command line options parsing. (#6787)
- Fix ``LoggingProxy.write()`` return type. (#6791)
- Couchdb key is now always coerced into a string. (#6781)
- grp is no longer imported unconditionally. (#6804)
    This fixes a regression in 5.1.0 when running Celery in non-unix systems.
- Ensure regen utility class gets marked as done when concertised. (#6789)
- Preserve call/errbacks of replaced tasks. (#6770)
- Use single-lookahead for regen consumption. (#6799)
- Revoked tasks are no longer incorrectly marked as retried. (#6812, #6816)

  to terminate tasks with late acknowledgement on connection loss. (#6654)

  when ``Request.on_failure`` is called. (#6654)
- Restore pickling support for ``Retry``. (#6748)
- Add support in the redis result backend for authenticating with a username. (#6750)
- The :setting:`worker_pool` setting is now respected correctly. (#6711)
