Red Hat Application Stack Errata Support Policy

Overview

Red Hat has established fixed life cycles for the Red Hat Application Stack which will allow customers and partners to plan their resources, certifications, and implementations accordingly.

To facilitate customer maintenance cycles, each Red Hat Application Stack will be supported via errata Service Packs. These Service Packs will contain security, bug fix, and enhancement errata that have been qualified on the appropriate Red Hat Application Stack release. Security errata will be the only errata released independent of Service Packs. To minimize the impact of security errata, Red Hat has a policy of back-porting security fixes whenever possible.

Details

For a period of three years from the initial release (General Availability), Red Hat will provide errata maintenance for each Application Stack. To facilitate and retain the high standard of stability inherent in the Red Hat enterprise products, the three years are divided into two phases of maintenance.

Timeline

This table summarizes the two support phases after General Availability (GA) of a major release.
