What kind of firmware releases are there?

Code level maintenance for software releases is typically delivered in form of Major Version updates, Stable Releases or Private Builds.

Private Builds are minor updates of the Major VersionStable Releases are public available interims releases, base for both kinds are the latest released Major Version. When an updated Major Version is released, it will compensate all of the previous firmware versions unless otherwise noted by IGEL.

Special case is a Dead End Release, which is a special kind of Private Build. Support for these versions is given and will be handled like usual Private Builds.
