PubSub+ Cloud Release Stages Overview

PubSub+ Cloud organizes its products and features to belong to one of the following launch stages:

  • Preview
  • Early Access
  • Beta
  • Controlled Availability
  • General Availability
  • Deprecated.

Access to features in certain release stages will either be provided automatically after system upgrades, or special requests may be made to Solace. For details on the meaning of each release stage in PubSub+ Cloud, see below.

Feature may not go through every release stage.


Preview features are limited-availability features where designs are not yet completed or cleared for more widespread use. Our focus for preview features is to generate interest, elicit requirement discussion, and gather feedback from a limited set of customers. Typically, preview feature participation is by invitation or opt-in. No Service Level Agreements (SLAs) are provided, and there are no technical support obligations. However, preview features are generally suitable for use in test environments.

Early Access

Early Access (EA) feature releases are limited to a closed group of testers for a limited subset of feature launches. Participation is optional or by invitation and may require signing an agreement before the feature release becomes General Available, including confidentiality provisions. These features may be unstable, change in backward-incompatible ways, and are not guaranteed to be released. There are no SLAs provided and no technical support obligations. Early Access feature releases are rare and focus on validating new product capabilities.


At Beta, products or features are ready for broader customer testing and use. Betas often publicly announced. There are no SLAs or technical support obligations in a Beta release unless otherwise specified in product terms or the terms of a particular beta program. Products are complete from a feature perspective, but may have some outstanding open issues.

Controlled Availability

Controlled Availability (CA) products and features are fully functional and available to customers upon request. These features are targeted for specific use cases, may require Solace to enable, and often requires additional support from Solace to configure. Our SLAs cover CA features, but the coverage may be subject to limitations or specific use cases.

General Availability

General Availability (GA) products and features are open to all customers, covered by our SLAs, and are ready for production use.


Deprecated features are scheduled to be shut down and removed. Deprecation, shutdown, or removal timelines are communicated, and customers are encouraged to contact Solace support if deprecation will have an impact on their business.

The above stages are specific to PubSub+ Cloud. For the details on our software and hardware broker products, see the Solace product lifecycle.
