4 Technology Previews

Technology previews are packages, stacks, or features delivered by SUSE. These features are not supported. They may be functionally incomplete, unstable or in other ways not suitable for production use. They are mainly included for customer convenience and give customers a chance to test new technologies within an enterprise environment.

Whether a technical preview will be moved to a fully supported package later, depends on customer and market feedback. A technical preview does not automatically result in support at a later point in time. Technical previews can be dropped at any time and SUSE is not committed to providing a technical preview later in the product cycle.

Give your SUSE representative feedback, including your experience and use case.
