v0.4.1: Check for session errors in attachLink

Previously attachLink did not check for session level errors, causing
link attachment to block forever in the case of an error. This change
resolves that and properly returns the error to the caller.

v0.4.0

Thank you to @amenzhinsky and @devigned for their contributions to this release!

• Add support for setting connection properties via ConnProperty option. (@devigned, ccafaa7)
• Add Message.Format field to allow getting/setting the message format. (54320c8)
• Add support for multiple data sections. (9c101f5)

Breaking Changes

• Message.Data has been changed from []byte to [][]byte to support multiple data sections.
  • NewMessage added to simplify constructing messages with a single data section.
  • Message.GetData added to simplify retreiving the first data section from a message.
• Message.DeliveryAnnotations, Message.Annotations, and Message.Footer are now defined as type Annotations. Annotations only supports keys of type string, int, and int64.
• Port for "amqps" now defaults to 5671 instead of 5672.
• Go int and uint now always encode/decode as long and ulong.
• Sessions are now ended when calling Session.Close. Previously this only deallocated the session locally.
• Max number number of sessions per connection changed from 1 to 65536.

v0.3.0: Support setting source selector filter (#5)

• Adds support for setting source selector filter with LinkSelectorFilter().

This addition allows clients to communicate offsets to Azure Event Hubs.

• Fixed marshaling/unmarshaling issues found in #4.

v0.2.0

Summary

• Support for sending messages.
• Support for sending/receiving "value" payloads.
• Added option LinkAddressDynamic(), Sender.Address() and Receiver.Address() to support dynamic addresses.
• Added options LinkSenderSettle() and LinkReceiverSettle() to allow for configuring settlement modes.
• Added option ConnSASLAnonymous() to enable SASL ANONYMOUS authentication.
• UUID support.
• Added basic integration tests against Microsoft Azure Service Bus.
• Debug logging when built with debug build tag.
• Many bug fixes.

Breaking Changes

• Option LinkSource() renamed to LinkAddress().
