E2B released CLI 2.23.0 on October 28, 2026. The notable change is command-line compatibility for template management, not a new sandbox runtime.

Check template-management scripts

Template listing now paginates through the templates API. Human-readable output defaults to a limit of 1,000 templates, while JSON output remains unlimited. The limit flag changes that behavior, with zero meaning no limit.

The interactive selection mode has been removed from template delete, publish and unpublish. Those commands now require a template argument; unused project and team options were removed as well.

Before upgrading an automated template workflow, check its arguments rather than assuming its previous interactive path still exists. This release does not announce free hosted sandbox execution or a change to service pricing.
