- Dropped python 3.4

- Bump py-amqp to 2.5.0

- Use SIMEMBERS instead of SMEMBERS to check for queue (redis broker)

* Add `_lookup_direct` method to virtual channel. (994)

Add possibility to optimize lookup for queue in direct
exchange set.

* Add `_lookup_direct` method to redis virtual channel. (994)

Use `SISMEMBER` instead of `SMEMBERS` command to check if queue
exists in a set. Time complexity is increased from O(N) to O(1)
where N is the set cardinality.

- Include priority in properties only if it's not None.
Since we attempt to serialize the priority property if it exists
in the dictionary it must be an integer.

- Removed dangerous default mutable arguments from function
definitions where appropriate.

=====
:release-date: 2019-03-3 18:30 P.M UTC+3:00
:release-by: Omer Katz

- 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.

- 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'
