 | 0.1.1   | Prometheus metrics logging. Workers/Threads/Workers class is able to set by environments. Streaming fixes. Multi-providers for single model with default-balanced strategy.                                                                                                                 |
 | 0.2.0   | Add balancing strategies: `balanced`, `weighted`, `dynamic_weighted` and `first_available` which works for streaming and non streaming requests. Included Prometheus metrics logging via `/metrics` endpoint. First stage of `llm_router_lib` library, to simply usage of `llm-router-api`. |
 | 0.2.1   | Fix stream: OpenAI->Ollama, Ollama->OpenAI. Add Redis caching of availability of model providers (when using `first_available` strategy). Add `llm_router_web` module with simple flask-based frontend to manage llm-router config files.                                                   |
