The document focuses primarily on issues of software backwards-compatibility. The purpose of this document is to provide guidance regarding the stability of applications and libraries written for RHEL and run under newer releases of RHEL. It outlines the tiered framework under which applications are considered compatible or not compatible. This document describes the recommended uses of the system application programming (API) and binary interfaces (ABI) that are intended to provide compatibility across Red Hat® Enterprise Linux® releases.
ISV and customer applications can reduce or avoid migration issues between major and minor Red Hat® Enterprise Linux® versions by following these guidelines during application development. This guide is intended to provide software developers with Red Hat's guidelines regarding support of third-party applications across multiple releases of the Red Hat® Enterprise Linux® platform. For Red hat Enterprise Linux 7 please see the Red Hat Enterprise Linux 7: Application Compatibility GUIDE. Note: this article discusses Application Compatibility for Red Hat Enterprise Linux 8.
