Errata advisories may contain security fixes (Red Hat Security Advisories or RHSAs), bug fixes (Red Hat Bug Fix Advisories or RHBAs), or feature enhancements (Red Hat Enhancement Advisories or RHEAs).
Errata advisories are tested and qualified against the active Red Hat Enterprise Linux major release.
During the Extended Life Phase, a Red Hat Enterprise Linux subscription provides continued access to previously released content on the Red Hat Customer Portal, as well as other content such as documentation and the Red Hat Knowledgebase.
Advice for migrating to currently supported Red Hat Enterprise Linux versions may also be provided.
(For example, a Red Hat Enterprise Linux 8 RHSA will be applied cumulatively to the latest Red Hat Enterprise Linux 8 version and patch set.) Released errata advisories remain accessible to active subscribers for the entire Red Hat Enterprise Linux life cycle.
Minor releases will also include all available and qualified errata.
With the introduction of Red Hat Enterprise Linux version 8, Red Hat is simplifying the RHEL product phases from four to three: Full Support, Maintenance Support, and Extended Life Phase.
We are also providing information on anticipated release dates and minor releases that will offer extended support. Errata advisories may be released individually on an as-needed basis or aggregated as a minor release.
Furthermore, major releases of Red Hat Enterprise Linux contain a limited set of backward-compatible libraries included in previous major releases to allow for the easy migration of applications.
Typically, Red Hat applies changes in such a way as to minimize the amount of change and to maintain binary compatibility.
