Elevator Pitch

• Deno 2.8 is a major minor release that adds new CLI subcommands, improves Node compatibility and performance, and expands debugging, workspace, and Web API capabilities.

Key Takeaways

• Adds several new CLI tools (deno audit fix, deno bump-version, deno ci, deno pack, deno transpile, deno why) to streamline security, releases, CI installs, packaging, transpilation, and dependency tracing.
• Improves Node and npm ergonomics: unprefixed CLI installs default to npm, Node test-suite pass rate jumps to 76.4%, and many performance benchmarks show multi‑x gains (notably cold npm installs).
• Expands platform features: import defer, better Chrome DevTools debugging (including network inspection), OpenTelemetry improvements, workspace dependency catalogs, and new/filled-in Web APIs (e.g., OffscreenCanvas, transferable streams).
