    [MessageSenderAsync.send_async]{.title-ref} is now a coroutine.

-   **Breaking change** Removed [detach_received]{.title-ref} callback
    argument from MessageSender, MessageReceiver, MessageSenderAsync,
    and MessageReceiverAsync in favour of new [error_policy]{.title-ref}
    argument.

-   Added ErrorPolicy class to determine how the client should respond
    to both generic AMQP errors and custom or vendor-specific errors. A
    default policy will be used, but a custom policy can be added to any
    client by using a new [error_policy]{.title-ref} argument. Value
    must be either an instance or subclass of ErrorPolicy.

    > -   The [error_policy]{.title-ref} argument has also been added to
    >     MessageSender, MessageReceiver, Connection, and their async
    >     counterparts to allow for handling of link DETACH and
    >     connection CLOSE events.
    > -   The error policy passed to a SendClient determines the number
    >     of message send retry attempts. This replaces the previous
    >     [constants.MESSAGE_SEND_RETRIES]{.title-ref} value which is
    >     now deprecated.
    > -   Added new ErrorAction object to determine how a client should
    >     respond to an error. It has three properties:
    >     [retry]{.title-ref} (a boolean to determine whether the error
    >     is retryable), [backoff]{.title-ref} (an integer to determine
    >     how long the client should wait before retrying, default is 0)
    >     and [increment_retries]{.title-ref} (a boolean to determine
    >     whether the error should count against the maximum retry
    >     attempts, default is [True]{.title-ref}). Currently
    >     [backoff]{.title-ref} and [increment_retries]{.title-ref} are
    >     only considered for message send failures.
    > -   Added [VendorConnectionClose]{.title-ref} and
    >     [VendorLinkDetach]{.title-ref} exceptions for non-standard
    >     (unrecognized) connection/link errors.

-   Added support for HTTP proxy configuration.

-   Added support for running async clients synchronously.

-   Added keep-alive support for connection - this is a background
    thread for a synchronous client, and a background async function for
    an async client. The keep-alive feature is disabled by default, to
    enable, set the [keep_alive_interval]{.title-ref} argument on the
    client to an integer representing the number of seconds between
    connection pings.

-   Added support for catching a Connection CLOSE event.

-   Added support for [Connection.sleep]{.title-ref} and
    [ConnectionAsync.sleep_async]{.title-ref} to pause the connection.

-   Added support for surfacing message disposition delivery-state (with
    error information).

-   Added [constants.ErrorCodes]{.title-ref} enum to map standard AMQP
    error conditions. This replaces the previous
    [constants.ERROR_CONNECTION_REDIRECT]{.title-ref} and
    [constants.ERROR_LINK_REDIRECT]{.title-ref} which are now both
    deprecated.

-   Added new super error [AMQPError]{.title-ref} from which all
    exceptions inherit.

    [AMQPConnectionError]{.title-ref}, for Senders/Receivers that enter
    an indeterminate error state.

-   [MessageException]{.title-ref} is now a subclass of
    [MessageResponse]{.title-ref}.

-   Added [ClientMessageError]{.title-ref} exception, a subclass of
    [MessageException]{.title-ref} for send errors raised client-side.

    service returns delivery-state.

    link crashed the client.

    the submodule can now be accessed from uamqp or uamqp.authentication
    directly.

-   **Breaking change** Anything returned by a callback supplied to
    receive messages will now be ignored.

-   **Breaking change** Changed message state enum values:

    > -   [Complete -\> SendComplete]{.title-ref}

    > -   [WaitingForAck -\> WaitingForSendAck]{.title-ref}

-   Added new message state enum values:

    > -   [ReceivedUnsettled]{.title-ref}
    > -   [ReceivedSettled]{.title-ref}

-   **Breaking change** Changes to message settlement exceptions:

    > -   Combined the [AbandonMessage]{.title-ref} and
    >     [DeferMessage]{.title-ref} exceptions as
    >     [MessageModified]{.title-ref} to be in keeping with the AMQP
    >     specification.
    > -   Renamed [AcceptMessage]{.title-ref} to
    >     [MessageAccepted]{.title-ref}.
    > -   Renamed [RejectMessage]{.title-ref} to

-   A received Message can now be explicitly settled through a set of
    new functions on the message:

    > -   [Message.accept()]{.title-ref}
    > -   [Message.reject(condition:str, description:str)]{.title-ref}
    > -   [Message.release()]{.title-ref}
    > -   [Message.modify(failed:bool, deliverable:bool,
    >     annotations:dict)]{.title-ref}

-   Added explicit [auto_complete]{.title-ref} argument to
    [ReceiveClient]{.title-ref} and [ReceiveClientAsync]{.title-ref}. If
    [auto_complete]{.title-ref} is set to [False]{.title-ref} then all
    messages must be explicitly \"accepted\" or \"rejected\" by the user
    otherwise they will timeout and be released. The default is
    [True]{.title-ref}, which is the exiting behaviour for each receive
    mechanism:

    > -   Received messages processed by callback
    >     ([ReceiveClient.receive_messages()]{.title-ref}) will be
    >     automatically \"accepted\" if no explicit response has been
    >     set on completion of the callback.
    > -   Received messages processed by batch
    >     ([ReceiveClient.receive_message_batch()]{.title-ref}) will by
    >     automatically \"accepted\" before being returned to the user.
    > -   Received messages processed by iterator
    >     ([ReceiveClient.receive_message_iter()]{.title-ref}) will by
    >     automatically \"accepted\" if no explicit response has been
    >     set once the generator is incremented.

-   Added new methods to clients and connections to allow to redirect to
    an alternative endpoint when a LinkRedirect exception is raised. The
    client redirect helper cannot be used for clients that use a shared
    connection - the clients must be closed before the connection can be
    redirected. New credentials must be supplied for the new endpoint.
    The new methods are:

    > -   [uamqp.Connection.redirect(redirect_info, auth)]{.title-ref}
    > -   [uamqp.async.ConnectionAsync.redirect_async(redirect_info,
    >     auth)]{.title-ref}
    > -   [uamqp.SendClient.redirect(redirect_info, auth)]{.title-ref}
    > -   [uamqp.ReceiveClient.redirect(redirect_info,
    >     auth)]{.title-ref}
    > -   [uamqp.async.SendClientAsync.redirect_async(redirect_info,
    >     auth)]{.title-ref}
    > -   [uamqp.async.ReceiveClientAsync.redirect_async(redirect_info,
    >     auth)]{.title-ref}

-   Added [on_detach_received]{.title-ref} argument to
    [Sender]{.title-ref} and [Receiver]{.title-ref} classes to pass in
    callback to run on Link DETACH.

-   Removed automatic char encoding for strings of length 1, and added
    [types.AMQPChar]{.title-ref} for explicit encoding.
