Internal Architecture Changes

Dependency Updates

• Removed legacy polyfills: Removed Microsoft tslib polyfills (Vj1) and several older semver-related modules (ti, XY1)
• Added ES module introspection utilities: New low-level JavaScript runtime introspection modules for better error handling and type checking
• Enhanced runtime environment detection: Added comprehensive checks for JavaScript built-in objects and methods

JSON Schema Processing Enhancements

• New schema validation options:
• Added allowedAdditionalProperties configuration option (default: true)
• Added rejectedAdditionalProperties configuration option (default: false)
• These options provide finer control over how additional properties in JSON schemas are handled during validation
• Post-processing support: Added postProcess callback support in the JSON schema generation pipeline, allowing for custom transformations after schema generation

Tool System Improvements

• Removed deprecated todo tool: The internal tengu_todo_tool reference has been removed from the codebase
• Enhanced error handling: Improved type checking for tool parameters with better runtime validation

Event Stream Processing

• Improved SSE parser: Enhanced Server-Sent Events parser with better error handling and support for BOM (Byte Order Mark) detection
• Added stream reset options: New consume parameter in the reset function for better stream state management

Performance and Stability

• Code simplification: Removed approximately 44 deprecated functions while adding 473 new utility functions
• Better type safety: Enhanced runtime type checking with new introspection utilities
• Improved error messages: More descriptive error reporting with enhanced type validation
