Summary: Bun launches v1.3.6 with new Archive and JSONC APIs

Why It Matters: Bun is expanding its built-in toolkit to handle more complex file tasks like compression and JSON parsing with comments. This makes it even easier for developers to stop using external libraries.

What Changed:

  • Updated the main version from v1.3.5 to v1.3.6.
  • Added the Bun.Archive API for creating and extracting tarballs with gzip.
  • Added the Bun.JSONC API for parsing JSON files that contain comments.
  • Added a new "Four tools, one toolkit" section that clearly breaks down the Runtime, Package Manager, Test Runner, and Bundler.
  • Added new social proof mentions for Claude Code and Midjourney.
  • Added a code example showing how Bun works with Next.js.
  • Added a categorized API directory covering Databases, Security, and System Integration.
