## ✨ Features

- **Custom SSE Stream Reader** — Replaced fasthttp's default stream reader with a custom implementation to reduce bursts in SSE streaming
- **MCP Config Validation** — Added validation for MCP tool configurations in config.json
- **Max Open Connections** — Exposed max-open-connections for provider domains as a configurable field
- **Dashboard improvements** - Added a bunch of new tabs and new graphs to the dashboard including Model Ranking, Cache usage, MCP usage etc
- **Improved dashboard and logs performance** - We have improved LLM logs and Dashboard UI performance (~1400x faster) for large number of logs. 

## 🐞 Fixed

- **Passthrough Streaming** — Fixed passthrough streaming responses being buffered instead of streamed (thanks [@jasonwells](https://github.com/jasonwells)!)
- **MCP Notifications** — Fixed MCP notifications returning incorrect status code (thanks [@tcx4c70](https://github.com/tcx4c70)!)
- **Streaming Function Calls** — Fixed function_call items not included in streaming response.completed output (thanks [@majiayu000](https://github.com/majiayu000)!)
- **Bedrock API Key Auth** — Fixed Bedrock API key authentication without requiring bedrock_key_config (thanks [@eliasbiondo](https://github.com/eliasbiondo)!)
- **Bedrock Token Count Fallback** — Added fallback to estimated token count when count-tokens API is unsupported (thanks [@Edward-Upton](https://github.com/Edward-Upton)!)
- **Anthropic Thinking Fixes** — Fixed OpenAI-to-Anthropic-to-OpenAI thinking content conversion
- **Anthropic Header Selection** — Fixed Anthropic header selection across providers
- **Gemini OpenAI Integration** — Fixed Gemini flow for OpenAI-compatible integration
- **Semantic Cache Hashing** — Fixed deterministic tools_hash and params_hash in semantic cache (thanks [@ragokan](https://github.com/ragokan)!)
- **Anthropic Compaction** — Added compaction support for Anthropic provider
