Software Releases Overview

Code-level maintenance for software releases is typically delivered in form of Major Version updates, Stable Releases, Rolling Releases (since IGEL OS 11.07), or Private Builds.

Stable Releases and Rolling Releases are publicly available interim releases.

Rolling Releases are offered with a rough cadence of three weeks and include all current bug fixes, added features, and client updates. This includes any new content that has been provided via Private Build within that timeframe.

Stable Releases, Roling Releases, and Private Builds are based on the latest Major Version.

When an updated Major Version is released, it will replace all the previous firmware versions unless otherwise noted by IGEL.

A Dead End Release is a special kind of Private Build. IGEL Support is provided like with regular Private Builds.
