This eliminates command-based version checking and removes the need for the <code>deployment.version</code> configuration in agent type definitions.</li> <li>Replaced the <code>filesystem</code> configuration in on-host agent type definitions with an explicit, recursive, tagged-kind tree structure where every entry declares <code>kind: file | dir | dir_content_from_map</code> and <code>dir</code> entries nest using <code>entries:</code>.</li> <li>Introduced a <code>persistent</code> flag (default value is set to <code>false</code>) for on-host filesystem entries; ephemeral entries are deleted when a sub-agent stops, while persistent entries remain until the agent is removed from the <code>fleet.Reconciliation</code> across writes is driven by a <code>.ac-managed-paths.json</code> manifest (reserved filename — agent types must not declare it) so paths Agent Control no longer owns are deleted while sub-agent-created files are preserved.</li> <li>Introduced the <code>shared-filesystem-dir </code>variable for agent type configurations.</li> <li>Extended the internal <code>fs</code> crate to support file copy operations.</li> <li>Removed the filesystem manifest-based prune mechanism; Agent Control no longer deletes previously-declared paths dropped by subsequent configurations; agent-managed files are now reclaimed only when the agent is removed from the fleet.</li> </ul> <h2>Fixes</h2> <ul> <li>Fixed an on-host self-update issue where pushing an empty <code>version: ""</code> string from Fleet Control incorrectly triggered an image pull of the <code>:latest</code> OCI tag. It now correctly treats an empty string as a no-op (), matching the behavior of an absent version field.</li> </ul> <p>For a detailed description of changes, see the <a href="https://github.com/newrelic/newrelic-super-agent/releases/tag/1.18.0">release notes</a>.</p>ReleasedOn: Mon, 06 Jul 2026 00:00:00 +0000.
