## Executive Summary (TL;DR)
Bun bun-v0.0.41. Source highlight: `bun run ./file.js` now supports running JavaScript, TS, TSX, and JSX files using Bun.js. If you pass `bun run`  a filepath to a `.js`, `.jsx`, `.tsx`, or `.ts` file, it will run it with Bun.js instead of saying `"error: Missing script"`. This is very experimental!

## Improvements
- `performance.now()` is implemented

## Bug Fixes
- [.env loader] functions from bash were exported incorrectly due to parsing process environment variables similarly to `.env` files which is unnecessary. Now process environment variables are passed through without extra parsing
- `fetch()` wasn't working due to a silly mistake. That's fixed
