Which releases of Red Hat Enterprise Linux or derivatives does EPEL project provides packages for?
EPEL project provides add-on packages for Red Hat Enterprise Linux 5.x and 4.x releases and compatible derivatives. Packages for Red Hat Enterprise Linux 3 and 2.1 are not provided since they are under maintenance phase following the errata support policy from Red Hat and packages sourced from Fedora is unlikely to build properly against the older version of packages available in these releases making it very difficult to maintain properly.
