# Runner Recovery & FUSE Optimization

Published: 2026-03-20 · Version: v0.154.0

This release improves runner reliability with in-place sandbox recovery during draining and optimized single FUSE mounts per volume.

This release improves runner reliability and resource efficiency. Sandboxes marked as recoverable on draining runners are now recovered in-place by expanding disk by 5% and resetting state, preventing infinite retry loops caused by disk-full conditions during migration.

FUSE volume mounts have been optimized to use a single mount per volume with bind subdirectories for subpaths, significantly reducing the number of mount-s3 processes and idle CPU usage on runners. The runner also replaces fragile log-parsing for snapshot pull detection with a thread-safe in-memory tracker.

Additional fixes include permission-gated sandbox creation on the dashboard, Python SDK delete timeouts, reduced API log spam on archive, and documentation for entrypoint session details.
