A. Technology Previews

Technology Preview features are currently not supported under Red Hat Enterprise Linux 4.9 subscription services, may not be functionally complete, and are generally not suitable for production use. However, these features are included as a customer convenience and to provide the feature with wider exposure.
Customers may find these features useful in a non-production environment. Customers are also free to provide feedback and functionality suggestions for a technology preview feature before it becomes fully supported. Erratas will be provided for high-severity security issues.
During the development of a technology preview feature, additional components may become available to the public for testing. It is the intention of Red Hat to fully support technology preview features in a future release.
For more information on the scope of Technology Previews in Red Hat Enterprise Linux, please view the Technology Preview Features Support Scope page on the Red Hat website.
