:release-by: Omer Katz

- Added Python 3.7 support.

Contributed by **Omer Katz**, **Mads Jensen** and **Asif Saif Uddin**

- Avoid caching queues which are declared with a TTL.

Queues that are declared with a TTL are now also be excluded from the
in-memory cache in case they expire between publishes on the same channel.

Contributed by **Matt Yule-Bennett**

- Added an index to the Message table for the SQLAlchemy transport.

The index allows to effectively sorting the table by the message's timestamp.

.. note::

 We do not provide migrations for this model yet.
 You will need to add the index manually if you are already
 using the SQLAlchemy transport.

 The syntax may vary between databases.
 Please refer to your database's documentation for instructions.

Contributed by **Mikhail Shcherbinin**

- Added a timeout that limits the amount of time we retry
to reconnect to a transport.

Contributed by **:github_user:`tothegump`**

- :class:``celery.asynchronous.hub.Hub`` is now reentrant.

This allows calling :func:`celery.bin.celery.main` to revive a worker in
the same process after rescuing from shutdown (:class:``SystemExit``).

Contributed by **Alan Justino da Silva**

- Queues now accept string exchange names as arguments as documented.

Tests were added to avoid further regressions.

Contributed by **Antonio Gutierrez**

- Specifying names for broadcast queues now work as expected.

Previously, named broadcast queues did not create multiple queues per worker.
They incorrectly declared the named queue which resulted in one queue per
fanout exchange, thus missing the entire point of a fanout exchange.
The behavior is now matched to unnamed broadcast queues.

- When initializing the Redis transport in conjunction with gevent
restore all unacknowledged messages to queue.

Contributed by **Gal Cohen**

- Allow :class:``kombu.simple.SimpleQueue`` to pass queue_arguments to Queue object.

This allows :class:``kombu.simple.SimpleQueue`` to connect to RabbitMQ queues with
custom arguments like 'x-queue-mode'='lazy'.

Contributed by **C Blue Neeh**

- Add support for 'rediss' scheme for secure Redis connections.

The rediss scheme defaults to the least secure form, as
there is no suitable default location for `ca_certs`. The recommendation
would still be to follow the documentation and specify `broker_use_ssl` if
coming from celery.

Contributed by **Daniel Blair**

- Added the Azure Storage Queues transport.

The transport is implemented on top of Azure Storage
Queues. This offers a simple but scalable and low-cost PaaS
transport for Celery users in Azure. The transport is intended to be
used in conjunction with the Azure Block Blob Storage backend.

**Denis Kisselev**, **Evandro de Paula**, **Martin Peck**
and **:github_user:`michaelperel`**

- Added the Azure Service Bus transport.

The transport is implemented on top of Azure Service Bus and
offers PaaS support for more demanding Celery workloads in Azure.
The transport is intended to be used in conjunction with the Azure
CosmosDB backend.

and **:github_user:`michaelperel`**

- Drop remaining mentions of Jython support completely.

Contributed by **Asif Saif Uddin** and **Mads Jensen**

- When publishing messages to the Pidbox, retry if an error occurs.

Contributed by **Asif Saif Uddin**

- Fix infinite loop in :method:``kombu.asynchronous.hub.Hub.create_loop``.

Previous attempt to fix the problem (PR kombu/760) did not consider
an edge case. It is now fixed.

Contributed by **Vsevolod Strukchinsky**

- Worker shutdown no longer duplicates messages when using the SQS broker.

Contributed by **Mintu Kumar Sah**

- When using the SQS broker, prefer boto's default region before our hardcoded default.

Contributed by **Victor Villas**

- Fixed closing of shared redis sockets which previously caused Celery to hang.

Contributed by **Alexey Popravka**

- the `Pyro`_ transport (:mod:`kombu.transport.pyro`) now works with
recent Pyro versions. Also added a Pyro Kombu Broker that this transport
needs for its queues.

Contributed by **Irmen de Jong**

- Handle non-base64-encoded SQS messages.

Fix contributed by **Tim Li**, **Asif Saif Uddin** and **Omer Katz**.

- Move the handling of Sentinel failures to the redis library itself.

Previously, Redis Sentinel worked only if the first node's sentinel
service in the URI was up. A server outage would have caused downtime.

Contributed by **Brian Price**

- When using Celery and the pickle serializer with binary data as part of the
payload, `UnicodeDecodeError` would be raised as the content was not utf-8.
We now replace on errors.

Contributed by **Jian Dai**

- Allow setting :method:``boto3.sqs.create_queue`` Attributes via transport_options.

Contributed by **Hunter Fernandes**

- Fixed infinite loop when entity.channel is replaced by revive() on connection
drop.

Contributed by **Tzach Yarimi**

- Added optional support for Brotli compression.

Contributed by **Omer Katz**

- When using the SQS broker, FIFO queues with names that ended with the 'f' letter
were incorrectly parsed. This is now fixed.

Contributed by **Alex Vishnya** and **Ilya Konstantinov**

-  Added optional support for LZMA compression.

Contributed by **Omer Katz**

- Added optional support for ZStandard compression.

Contributed by **Omer Katz**

- Require py-amqp 2.4.0 as the minimum version.

Contributed by **Asif Saif Uddin**

- The value of DISABLE_TRACEBACKS environment variable is now respected on debug, info
and warning logger level.

Contributed by **Ludovic Rivallain**

- As documented in kombu/741 and eventlet/eventlet415
there is a mismatch between the monkey-patched eventlet queue
and the interface Kombu is expecting.
This causes Celery to crash when the `broker_pool_limit`
configuration option is set
eventlet/eventlet415 suggests that the mutex can be a noop.
This is now the case.
