  ## ✨ 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
