Red Hat Enterprise Linux for Real-time Product LifecycleRed Hat Enterprise Linux for Real-Time is a real-time computing platform for deadline-oriented applications and time-sensitive workloads. It is a separate and unique subscription that is distinct from a subscription for Red Hat Enterprise Linux although some technology is common to both.
*Each major version (X.0) of Red Hat Enterprise Linux for Real-Time is supported for a period of five years after the initial release (aka general availability or GA).
Red Hat Enterprise Linux for Real-Time may include new features for the first three years from general availability. After that three year period, only Critical and Important Security errata advisories (RHSAs) and Urgent Priority Bug Fix errata advisories (RHBAs) may be released as they become available. All updates, upgrades and feature enhancements are provided at Red Hat's discretion on an if and when available basis.
Extended life cycle programs such as Extended Update Support (EUS) and Extended Lifecycle Support (ELS) are not available with Red Hat Enterprise Linux for Real Time. All updates are provided on the latest minor release only.
