+## [0.1.0] - Unreleased
+
+### Added
+
+- Initial public release, extracted from Mobiletic's production Swiss-nLPD chatbot.
+- `Anonymizer` — pre-filter → LLM → regex fallback, bidirectional validation, deterministic coreference,
+  and de-collision across question and retrieved chunks (`anonymize`, `anonymizeChunks`, `deanonymize`).
+- `makeStreamDeanonymizer` — streaming-safe de-anonymization that never leaks a split placeholder.
+- `openAICompatibleProvider` — pluggable LLM detection over any OpenAI-compatible Chat Completions API.
+- `presets.swiss` and `presets.generic` regex pattern sets; fully configurable custom patterns.
+- Regex-only mode (no LLM provider required).
