Version 1.40.0

Guardrails

  • New guardrail — Image sharpness. Blocks images attached to a prompt that are too blurry (set a minimum sharpness). Sentinel’s second image guardrail, alongside image resolution.
  • Sharper language detection. The Language check guardrail detects a prompt’s language more accurately.

General

  • API reference. Endpoint descriptions improved for search and SEO.
  • Bug fixes.

Sentinel CLI — v0.4.2

  • See a Sentinel’s full policy. sentinel gateway status --details prints the Sentinel’s guardrails and token-optimization config alongside health and version.
  • Clearer failures. The CLI now checks up front that you have an Admin role and that your --sentinel-id exists — telling you exactly what’s wrong instead of failing with an unclear error.
  • Smoother flows. Prompts you to restart a running gateway after gateway update, and falls back to a test ping when the health check is unreachable.
