## Summary

Bun v1.3.8 introduces a built-in CommonMark-compliant Markdown parser written in Zig with three rendering modes: HTML output, custom callbacks for terminal/custom formatting, and React elements. The bundler now supports --metafile-md to generate LLM-friendly Markdown visualizations of module graphs for bundle analysis. This release fixes 8 issues including crashes in heap snapshots and node:vm, HTTP/2 stream handling for gRPC calls, and npm global installation on Windows.
