Legato Application Framework Release Process

Legato AF releases are not tied to any specific module product release. Once we have released Legato AF, module vendors (like Sierra Wireless) will take the Legato AF and integrate it into their own product release.

Legato AF Release Schedule VS Module Vendor Release Schedule



  • Legato AF Team posts release 17.07
  • Module Vendor takes release 17.07 and builds an associated Linux Distro to create a "Legato Platform"
