## Executive Summary (TL;DR)
Bun bun-v0.0.34. Source highlight: Slightly better `tsconfig.json` handling:

## New Features
- `jsxImportSource` support – if you set `jsxImportSource` to `"@emotion/react"`, JSX will auto-import from `"@emotion/react/jsx-dev-runtime"` instead of `"react/jsx-dev-runtime"`
- `jsxFragmentFactory` support – this lets you override what `<>` transforms into. By default it's `"Fragment"`, since `<>` becomes `React.Fragment` normally.
- `jsxFactory` support – if you set `jsxFactory` to `"h"`, when using the classic JSX runtime, it will run `h` instead of `createElement`

## Bug Fixes
- [fetch] Fix bug with HTTP request bodies for http (not https) requests
- Fix JSX transform edgecase with static children to match Babel's behavior (static === `children.length > 1`)
- Fix node_module resolver edgecase when resolving from the dev server (not `bun bun`) that happened when resolving workspace packages above the project root that expect dependencies from the project. This applied to pnpm
- Add a small end-to-end test for emotion JSX
- Add a small end-to-end test for React Context.Provider & Context.Consumer
