NeMo Guardrails v0.24.0 expands IORails coverage to 59 of 67 action surfaces
NVIDIA
v0.24.0 (Aug 26) brings the built-in IORails set to 59 of 67 action-backed input/output surfaces, adds F5 Guardrails integration, server health endpoints, namespaced self-check rails, and output checking via /v1/checks. Breaking changes: custom actions using @action(output_mapping=...) must return an explicit RailOutcome; hf-classifier extra removed; stricter validation for Chat Completions requests.
Why it matters
IORails reaching ~88% built-in coverage removes the need for most user-defined rails on common action surfaces; the new F5 integration adds another vendor option for enterprise policy enforcement.
