Updating

Update an agent

When an update is available, open the server in the control plane and click Update. Confirm the target version, then click Queue upgrade. The control plane sends a work item over the authenticated agent channel. The agent:

Downloads the target version of the agent binary from GitHub releases.
Verifies the SHA256 checksum.
Replaces the existing binary.
Restarts itself after installation.

No configuration or dependencies are changed during an update.
