 - **Concurrent Streaming Performance**: Implemented concurrent draining of streamed React components using the async gem. Instead of processing components sequentially, the system now uses a producer-consumer pattern with bounded buffering to allow multiple components to stream simultaneously while maintaining per-component chunk ordering. This significantly reduces latency and improves responsiveness when using `stream_view_containing_react_components`. [PR 2015](https://github.com/shakacode/react_on_rails/pull/2015) by [ihabadham](https://github.com/ihabadham).
 
 ### Added

 - Added `config.concurrent_component_streaming_buffer_size` configuration option to control the memory buffer size for concurrent component streaming (defaults to 64). This allows fine-tuning of memory usage vs. performance for streaming applications.

 - **Body Duplication Bug On Streaming**: Fixed a bug that happens while streaming if the node renderer connection closed after streaming some chunks to the client. [PR 1995](https://github.com/shakacode/react_on_rails/pull/1995) by [AbanoubGhadban](https://github.com/AbanoubGhadban).

 ### Deprecated
 
 - **Node Renderer Configuration**: Renamed `bundlePath` configuration option to `serverBundleCachePath` in the node renderer to better describe its purpose and avoid confusion with Shakapacker's public bundle path. The old `bundlePath` option continues to work with deprecation warnings. Both `RENDERER_SERVER_BUNDLE_CACHE_PATH` (new) and `RENDERER_BUNDLE_PATH` (deprecated) environment variables are supported.
