 | 0.2.4   | Anonymizer module, integration anonymization with any endpoint (using dynamic payload analysis and full payload anonymisation), dedicated `/api/anonymize_text` endpoint as memory only anonymization. Whole router may be run in `FORCE_ANONYMISATION` mode.                               |
 | 0.3.0   | Anonymization available with three strategies: `fast_masker`, `genai`, `prov_masker`.                                                                                                                                                                                                       |
 | 0.3.1   | Refactoring `lb.strategies` to be more flexible modular. Introduced `MaskerPipeline` and `GuardrailPipeline` both configured via env. Removed genai-based masking endpoint.                                                                                                                 |
-| 0.4.0   | The main repository is divided into dedicated ones: plugins, services, web — separate repositories. Clean up the whole repository. Examples of integration with llamaindex, langchain, openai, litellm and haystack.                                                                        |
