NeMo Guardrails 0.23.0 also adds lightweight Hugging Face classifier rails, context bloat detection, and a Polygraf integration for PII detection and masking. Exact NumPy search replaces Annoy as the default embedding index, removing the native C++ dependency while preserving existing similarity-threshold semantics.
