py-amqp is fork of amqplib used by Kombu containing additional features and improvements.
The previous amqplib changelog is here:
.. _version-1.4.6:
:release-date: 2014-08-11 06:00 P.M UTC
:release-by: Ask Solem
- Now keeps buffer when socket times out.
Fix contributed by Artyom Koval.
- Adds ``Connection.Transport`` attribute that can be used to specify
a different transport implementation.
Contributed by Yury Selivanov.
.. _version-1.4.5:
:release-date: 2014-04-15 09:00 P.M UTC
:release-by: Ask Solem
- Can now deserialize more AMQP types.
Now handles types ``short string``, ``short short int``,
``short short unsigned int``, ``short int``, ``short unsigned int``,
``long unsigned int``, ``long long int``, ``long long unsigned int``
and ``float`` which for some reason was missing, even in the original
amqplib module.
- SSL: Workaround for Python SSL bug.
A bug in the python socket library causes ````
on a closed socket to raise :exc:`AttributeError` instead of
Fix contributed by Craig Jellick.
- ``Transport.__del_`` now handles errors occurring at late interpreter
shutdown (Issue #36).
.. _version-1.4.4:
:release-date: 2014-03-03 04:00 P.M UTC
:release-by: Ask Solem
- SSL transport accidentally disconnected after read timeout.
Fix contributed by Craig Jellick.
.. _version-1.4.3:
:release-date: 2014-02-09 03:00 P.M UTC
:release-by: Ask Solem
- Fixed bug where more data was requested from the socket
than was actually needed.
Contributed by Ionel Cristian Mărieș.
.. _version-1.4.2:
:release-date: 2014-01-23 05:00 P.M UTC
- Heartbeat negotiation would use heartbeat value from server even
if heartbeat disabled (Issue #31).
.. _version-1.4.1:
:release-date: 2014-01-14 09:30 P.M UTC
:release-by: Ask Solem
- Fixed error occurring when heartbeats disabled.
.. _version-1.4.0:
:release-date: 2014-01-13 03:00 P.M UTC
:release-by: Ask Solem
- Heartbeat implementation improved (Issue #6).
The new heartbeat behavior is the same approach as taken by the
RabbitMQ java library.
This also means that clients should preferably call the ``heartbeat_tick``
method more frequently (like every second) instead of using the old
``rate`` argument (which is now ignored).
- Heartbeat interval is negotiated with the server.
- Some delay is allowed if the heartbeat is late.
- Monotonic time is used to keep track of the heartbeat
instead of relying on the caller to call the checking function
at the right time.
Contributed by Dustin J. Mitchell.
- NoneType is now supported in tables and arrays.
Contributed by Dominik Fässler.
- SSLTransport: Now handles ``ENOENT``.
Fix contributed by Adrien Guinet.
.. _version-1.3.3:
:release-date: 2013-11-11 03:30 P.M UTC
:release-by: Ask Solem
- SSLTransport: Now keeps read buffer if an exception is raised
(Issue #26).
Fix contributed by Tommie Gannert.
.. _version-1.3.2:
:release-date: 2013-10-29 02:00 P.M UTC
:release-by: Ask Solem
- is now a channel object (not the channel id).
- Bug in previous version caused the socket to be flagged as disconnected
.. _version-1.3.1:
:release-date: 2013-10-24 04:00 P.M UTC
:release-by: Ask Solem
- Now implements Connection.connected (Issue #22).
- Fixed bug where ``str(AMQPError)`` did not return string.
.. _version-1.3.0:
:release-date: 2013-09-04 02:39 P.M UTC
:release-by: Ask Solem
- Now sets ```` 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 ````,
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
Supporting fields: ``queue``, ``message_count``, and
- 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.

- Supports draining events from multiple channels (``Connection.drain_events``)
- Support for timeouts
- Support for heartbeats

(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.
- ``['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
- 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
