The Messaging API for Go now supports message NACK.

The Go API now supports end-to-end payload compression. Sessions can now be optionally configured to compress the payload of every message on a message-by-message basis. While enabling this feature severely impacts API performance for small messages and significantly impacts API performance for larger messages, it has a positive impact on Event Broker performance and message-spool usage.

Applications using the Go API can now dynamically add and remove durable endpoints.

The API now supports the request/reply messaging pattern with helper methods to await response from a replier.

Enables adding and extracting tracing metadata attached to events published and received by the Solace Go API.

We have simplified the API license text, and clarified that distributing works containing the Solace APIs is allowed.

The Go API now supports development and deployment on platforms that use ARM processors.

This enhancement adds support for Partitioned Queues to the API. Partitioned Queues expand PubSub+ to provide deterministic, ordered, and non-exclusive message delivery for customers to scale the number of consumers when publishing ordered datasets. The ordered datasets are keyed to ensure all events in the dataset are sent to the same consumer without mis-ordering events.

This feature requires PubSub+ Event Broker support. Support for this feature was introduced to the Event Broker in release 10.4.0.

The GO API now supports development and deployment on platforms that use MAC M-series processors.

This feature allows an application to automatically update the OAuth token without the need to create a new session the next time the API tries to reconnect.

The API now supports Alpine Linux, allowing developers to build and deploy applications using the API on this platform.

This is the first release of the PubSub+ Messaging API for Go. Solace created this API to support the growing Go ecosystem and to address customer demand to create applications in Go that can take advantage of the broad features of PubSub+. This API provides support for all deployments of PubSub+ across software, appliance, and cloud.

This version contains a feature set that allows for the common messaging patterns like publish/subscribe using Direct Messaging and Guaranteed Messaging. Future versions of the Go API will introduce more features as Solace builds out the roadmap for this API.

The Go API 1.0.0 supports:

* Connection management to PubSub+ Event Brokers

* Addition and removal of topic subscriptions

* Sending and receiving Direct and Guaranteed Messages

* Message compression

* Use of Selectors

* Message Replay

* Structured data types that allow interoperability between various architectures and programming languages

* Provisioning of persistent (durable) endpoints

* Kerberos authentication

* OAuth 2.0 authentication

The Go API 1.0.0 does not support the following:

* PubSub+ Cache Client API support

* Request/Reply message exchange pattern

* Session Transactions

* XA Transactions

* Queue browsing
