## What's new

A huge thank you to [@zhuzilin](https://github.com/zhuzilin) for all their help on this release. @zhuzilin fixed 4 crashes!

**`bun link`** lets you symlink a folder to node_modules. It works like npm link.

**`fs.copyFileSync`** gets 2x to 10x faster:

`require.resolve` works at runtime now instead of only build-time

`WebSocket` is more reliable now. Previously the garbage collector would attempt to free it when the socket was still open 🙉

`bun:ffi`'s `toBuffer` and `toArrayBuffer` functions now support a function pointer to a destructor so that native code can perform cleanup without needing to go through a `FinalizationRegistry`.

#### console.log

`TypedArray` logs the value for the type (instead of in bytes 🙈)

console.log(`MessageEvent` ) is more useful now

More:

- `setInterval` wouldn't cause the process to stay alive 😢 and now that is fixed thanks to [@zhuzilin](https://github.com/zhuzilin)
- Log error on unhandled rejected promises by [@zhuzilin](https://github.com/zhuzilin) in https://github.com/oven-sh/bun/pull/1010
- Log error on uncaught exceptions in event loop
- `bun install` gets a `symlink` backend, which you probably don't want to use in most cases. It's used internally if you do `file:./` as a dependency, which some packages do
- `process.revision` returns the git sha used to build bun
