July 2025: Key features delivered and reliability improvements for the sgl-lang router in ping1jing2/sglang. Implemented streaming support via StreamOptions in the router, enabling configurable streaming for CompletionRequest and ChatCompletionRequest, with a dedicated StreamOptions struct to control streaming behavior.
