📊 Bun 1.4 Now Passes 80% of Node's Test Suite — Bun 1.4's headline feature is a big jump in Node.js compatibility as part of its goal of being a "drop-in replacement". This page lets you see the project's progress and where Bun is strong and weak.

IN BRIEF:

• Matteo Collina has landed node:ffi enabled by default, so calling into a native C library will no longer need --experimental-ffi, an addon, or node-gyp. It remains experimental, warns on first load, and hasn't shipped in a release yet.

• Matteo has also added support for Single Executable Applications to mount their bundled assets as a read-only virtual file system by setting "useVfs": true in the config.

• 🔒 Express has patched six vulnerabilities across hbs, multer and morgan.

• Node's issue tracker reaches issue 2**16 with a proposal to remove dual ESM/CJS code samples in the API docs.
