v1.0.5

v1.0.4

Other Changes

• A Receiver's unsettled messages are tracked as a count (currently used for diagnostic purposes only).

v1.0.3

Bugs Fixed

• Fixed an issue that could cause a memory leak when settling messages across Receiver instances.

v1.0.2

Bugs Fixed

• Fixed an issue that could cause frames to be sent even when the provided context.Context was cancelled.
• Fixed a potential hang in Sender.Send() that could happen in rare circumstances.
• Ensure that Sender's delivery count and link credit are updated when a transfer fails to send due to context cancellation/timeout.

v1.0.1

Bugs Fixed

• Fixed an issue that could cause links to terminate with error "received disposition frame with unknown link handle X".

v1.0.0

Features Added

• Added ConnOptions.WriteTimeout to control the write deadline when writing to net.Conn.

Bugs Fixed

• Calling Dial() with a cancelled context doesn't create a connection.
• Context cancellation is properly honored in calls to Dial() and NewConn().
• Fixed potential race during Conn.Close().
• Disable sending frames when closing Session, Sender, and Receiver.
• Don't leak in-flight messages when a message settlement API is cancelled or times out waiting for acknowledgement.
• Sender.Send() will return an *amqp.Error with condition amqp.ErrCondTransferLimitExceeded when attempting to send a transfer on a link with no credit.
• Sender.Send() will return an *amqp.Error with condition amqp.ErrCondMessageSizeExceeded if the message or delivery tag size exceeds the maximum allowed size for the link.

Other Changes

• Debug logging includes the address of the object that's writing a log entry.
• Context expiration or cancellation when creating instances of Session, Receiver, and Sender no longer result in the potential for Conn to unexpectedly terminate.
• Session channel and link handle exhaustion will now return *ConnError and *SessionError respectively, closing the respective Conn or Session.
• If a context.Context contains a deadline/timeout, that value will be used as the write deadline when writing to net.Conn.
