## What's new

**`bun init` quickly start a new, empty project that uses Bun** (similar to npm init). `bun init` is a new subcommand in `bun`.

**`bun install` now supports private npm registries & scoped (authenticated) packages**

Thank you @soneymathew for your help with this.

**`bun install` now supports lifecycle hooks for project-level package.json** (not dependencies)

It runs postinstall scripts for your app's package.json, but ignores dependencies lifecycle hooks. This lets you use `husky`, `lint-staged`, and other postinstall-dependent packages tools

More new stuff:

- `express` is partially supported, thanks to [@zhuzilin](https://github.com/zhuzilin) and @evanwashere. There is a lot more work to be done - it's not fast yet and it logs a spurious error on request, but it is better than not working
- `bun create` now lets you specify a start command so that you can say how to run the program in the output
- `process.revision` has the git sha that bun was built with

## Breaking changes

- bun install will invalidate the lockfiles on upgrade if it exists. Unfortunately, this is necessary to support private/scoped package installs
