Legato Application Framework Release Process

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

Legato AF Release Schedule VS Target Vendor Release Schedule

Example:

Legato AF Team posts release 17.07
Processor Vendor takes release 17.07 and builds an associated Linux Distro to create a "Legato Platform"
Processor Vendor tests and releases a "Legato Platform" with their Modem Firmware as "Product Release Y"
Legato AF Team posts release 17.08, 17.09 and 17.10 without the Processor Vendor packaging it into a Product Release. Releases are able to installed with the vendor's Product Release Y, but may not be officially supported by the Processor Vendor.
Processor Vendor takes release 17.11 and creates a "Legato Platform" and "Product Release Z", and so on..

For any questions about the Product Releases please contact your Processor Vendor directly.
