All our libraries are considered as SOUP <span>(software of unknown pedigree/provenance)</span>.</p> <p>However, as this <a href="https://nrfconnectdocs.nordicsemi.com/ncs/latest/zephyr/safety/safety_overview.html#general-safety-scope">link </a>describes, the zephyr project has <i>something</i> on it. We try to align our&nbsp;<span>NCS v3.4.x </span> LTS release to use zephyr LTS, making it easier for the customer to atleast try to inherit/use whatever zephyr project has on this matter.</p> <p>Regards</p> <p>Pallavi</p><div style="clear:both;"></div>
