Wind River LTS releases are supported a minimum of 10 years under the normal support agreements, with additional support available through professional services.

The Wind River Linux LTS22 Distro is a binary distribution based on the Wind River Linux LTS22 distribution builder and is intended for intelligent edge solution developers who want to leverage the tremendous investment in embedded device hardware and open-source software made by Wind River but want to avoid the time and effort of building Linux from source.

The Distro provides multiple methods for solution developers to create a purpose-built Linux OS from binary images. These methods include: micro-start self-deploying images, Linux Assembly Tool (LAT), dnf package feeds, and a software development kit (SDK).

LTS 22 provides new capabilities for embedded solution developers to create their own customized embedded Linux OS that are supported by Wind River. For more information about LTS 22, see the documentation.
