.. _version-5.0.2:

5.0.6

=====
:release-date: 2021-04-01 10:45 A.M. UTC+6:00
:release-by: Asif Saif Uddin

- Change the order in which context.check_hostname and context.verify_mode get set
in SSLTransport._wrap_socket_sni. Fixes bug introduced in 5.0.3 where setting
context.verify_mode = ssl.CERT_NONE would raise
"ValueError: Cannot set verify_mode to CERT_NONE when check_hostname is enabled."
Setting context.check_hostname prior to setting context.verify_mode resolves the
issue.
- Remove TCP_USER_TIMEOUT option for Solaris (355) 
- Pass long_description to setup() (353)

5.0.5

=====
:release-date: 2021-01-28 4:30 P.M UTC+6:00
:release-by: Asif Saif Uddin

-  Removed mistakenly introduced code which was causing import errors



.. _version-5.0.4:

5.0.4

=====
:release-date: 2021-01-28 2:30 P.M UTC+6:00
:release-by: Asif Saif Uddin

-  Add missing load_default_certs() call to fix a regression in v5.0.3 release. (350)


.. _version-5.0.3:

5.0.3

=====
:release-date: 2021-01-19 9:00 P.M UTC+6:00
:release-by: Asif Saif Uddin

- Change the default value of ssl_version to None. When not set, the
proper value between ssl.PROTOCOL_TLS_CLIENT and ssl.PROTOCOL_TLS_SERVER
will be selected based on the param server_side in order to create
a TLS Context object with better defaults that fit the desired
connection side.

- Change the default value of cert_reqs to None. The default value
of ctx.verify_mode is ssl.CERT_NONE, but when ssl.PROTOCOL_TLS_CLIENT
is used, ctx.verify_mode defaults to ssl.CERT_REQUIRED.

- Fix context.check_hostname logic. Checking the hostname depends on
having support of the SNI TLS extension and being provided with a
server_hostname value. Another important thing to mention is that
enabling hostname checking automatically sets verify_mode from
ssl.CERT_NONE to ssl.CERT_REQUIRED in the stdlib ssl and it cannot
be set back to ssl.CERT_NONE as long as hostname checking is enabled.

- Refactor the SNI tests to test one thing at a time and removing some
tests that were being repeated over and over.

exists in a set. Time complexity is increased from O(N) to O(1)
where N is the set cardinality.

- The Redis transport now supports a custom separator for keys.

Previously when storing a key in Redis which represents a queue
we used the hardcored value ``\x06\x16`` separator to store
different attributes of the queue in the queue's name.

The separator is now configurable using the sep
transport option:

.. code-block:: python

 with Connection('redis://', transport_options={
         'sep': ':',
     }):
      ...
     pass

- When the SQS server returns a timeout we ignore it and keep trying
instead of raising an error.

This will prevent Celery from raising an error and hanging.

- Properly declare async support for the Qpid transport.

If you are using this transport we strongly urge you to upgrade.

Contributed by **Rohan McGovern**

- Revert `celery/kombu906 <https://github.com/celery/kombu/pull/906>`_ and
introduce unique broadcast queue names as an optional keyword argument.

If you want each broadcast queue to have a unique name specify `unique=True`:

.. code-block:: pycon

 >>> from kombu.common import Broadcast
 >>> q = Broadcast(queue='foo', unique=True)
 >>> q.name
 'foo.7ee1ac20-cda3-4966-aaf8-e7a3bb548688'
 >>> q = Broadcast(queue='foo')
 >>> q.name
 'foo'

- Restore bz2 import checks in compression module.

The checks were removed in `celery/kombu938 <https://github.com/celery/kombu/pull/938>`_ due to assumption that it only affected Jython.
However, bz2 support can be missing in Pythons built without bz2 support.

when parsing  Redis Sentinel master URI containing password.

Instead bump the required redis-py dependency to 3.2.0
to include this fix `andymccurdy/redis-py4e1e748 <https://github.com/andymccurdy/redis-py/commit/4e1e74809235edc19e03edb79c97c80a3e4e9eca>`_.
