Red Hat offers the Extended Update Support (EUS) Add-On to a Red Hat Enterprise Linux subscription for those customers who wish to standardize on a specific minor release for an extended period of time. The EUS Add-On allows customers the flexibility to decide when to take advantage of new Red Hat Enterprise Linux features, including new hardware enablement.
Under a Red Hat Enterprise Linux subscription, all available RHSAs and RHBAs are provided for the current active minor release until the availability of the next minor release. By contrast, EUS delivers—for a specific minor release—an independent, extended stream of those Critical impact RHSAs and selected Urgent Priority RHBAs that are available after that specific minor release and in parallel to subsequent minor releases. For EUS subscribers, Red Hat generally will continue to proactively provide Critical impact RHSAs independent of customer requests if and when available.
