Deployment compatibility
For Kubernetes, deploy this prerelease together with Helm chart 0.6.0. The unified execution backend configuration requires the matching chart; do not upgrade only the application image on an older chart. Remove tracecat.sandbox.disableNsjail from saved and supplied values, and select executor.backend and agentExecutor.backend explicitly (direct or nsjail; ephemeral is an alias for nsjail).
