py-amqp is fork of amqplib used by Kombu containing additional features and improvements.
The previous amqplib changelog is here:
http://code.google.com/p/py-amqplib/source/browse/CHANGES
.. _version-1.3.1:
1.3.1
=====
:release-date: 2013-10-24 04:00 P.M UTC
- Now implements Connection.connected (Issue #22).
- Fixed bug where ``str(AMQPError)`` did not return string.
.. _version-1.3.0:
1.3.0
=====
:release-date: 2013-09-04 02:39 P.M UTC
- Now sets ``Message.channel`` on delivery (Issue #12)
amqplib used to make the channel object available
as ``Message.delivery_info['channel']``, but this was removed
in py-amqp. librabbitmq sets ``Message.channel``,
which is a more reasonable solution in our opinion as that
keeps the delivery info intact.
- New option to wait for publish confirmations (Issue #3)
There is now a new Connection ``confirm_publish`` that will
force any ``basic_publish`` call to wait for confirmation.
Enabling publisher confirms like this degrades performance
considerably, but can be suitable for some applications
and now it's possible by configuration.
- ``queue_declare`` now returns named tuple of type
:class:`~amqp.protocol.basic_declare_ok_t`.
Supporting fields: ``queue``, ``message_count``, and
``consumer_count``.
- Contents of ``Channel.returned_messages`` is now named tuples.
Supporting fields: ``reply_code``, ``reply_text``, ``exchange``,
``routing_key``, and ``message``.
- Sockets now set to close on exec using the ``FD_CLOEXEC`` flag.
Currently only supported on platforms supporting this flag,
which does not include Windows.

Fix contributed by Andrew Grangaard
.. _version-0.9.1:
Version 0.9.1
=============
- Supports draining events from multiple channels (``Connection.drain_events``)
- Support for timeouts
- Support for heartbeats
- ``Connection.heartbeat_tick(rate=2)`` must called at regular intervals
(half of the heartbeat value if rate is 2).
- Or some other scheme by using ``Connection.send_heartbeat``.
- Supports RabbitMQ extensions:
- Consumer Cancel Notifications
- by default a cancel results in ``ChannelError`` being raised
- but not if a ``on_cancel`` callback is passed to ``basic_consume``.
- Publisher confirms
- ``Channel.confirm_select()`` enables publisher confirms.
- ``Channel.events['basic_ack'].append(my_callback)`` adds a callback
to be called when a message is confirmed. This callback is then
called with the signature ``(delivery_tag, multiple)``.
- Support for ``basic_return``
- Uses AMQP 0-9-1 instead of 0-8.
- ``Channel.access_request`` and ``ticket`` arguments to methods
**removed**.
- Supports the ``arguments`` argument to ``basic_consume``.
- ``internal`` argument to ``exchange_declare`` removed.
- ``auto_delete`` argument to ``exchange_declare`` deprecated
- ``insist`` argument to ``Connection`` removed.
- ``Channel.alerts`` has been removed.
- Support for ``Channel.basic_recover_async``.
- ``Channel.basic_recover`` deprecated.
- Exceptions renamed to have idiomatic names:
- ``AMQPException`` -> ``AMQPError``
- ``AMQPConnectionException`` -> ConnectionError``
- ``AMQPChannelException`` -> ChannelError``
- ``Connection.known_hosts`` removed.
- ``Connection`` no longer supports redirects.
- ``exchange`` argument to ``queue_bind`` can now be empty
to use the "default exchange".
- Adds ``Connection.is_alive`` that tries to detect
whether the connection can still be used.
- Adds ``Connection.connection_errors`` and ``.channel_errors``,
a list of recoverable errors.
- Exposes the underlying socket as ``Connection.sock``.
- Adds ``Channel.no_ack_consumers`` to keep track of consumer tags
that set the no_ack flag.
- Slightly better at error recovery
