Bun v0.0.22

Support resolving "exports" field in package.json. Webpack's guide does a great job explaining the "exports" field.
Add parsed lines of code counter to bun bun
Support importing files above the project root. HTTP Requests above the project root are allowlisted to specific file extensions to prevent common webserver security vulnerabilities like reading /etc/passwd. Absolute file path imports always start with abs:. The security questions aren't as relevant for localhost development, but still worth thinking about.
Support bundling symlinked workspace packages via bun bun. To use this, set "bun": { "alwaysBundle": ["packageName"] } in the project's package.json.
When bundling JSON, print the output as JSON.parse(jsonString) when the JSON is ASCII. JSON.parse is much faster for JavaScript engines to parse.

Implement console.time, console.timeEnd
Implement Bun.readFileBytes() to get a Uint8Array of the file's contents without copying.

Fix handling when file metadata store exceeds statically allocated count (at time of writing, 16k)
Always log errors when generating node_modules.server.bun
Fix how error lines with strings are highlighted
Fix parsing/printing JavaScript unicode identifiers
Slightly improve .env loader string detection
More correct export default transform for bundled code
Fix a JavaScript simplification bug involving ternaries
Fix a JavaScript parsing bug with arrays in function arguments that have default values
Fix edgecase with bare imports inside .bun
Fix edgecase with whether to wrap arrow expressions in parentheses when printing
Fix edgecase when a bundled module with multiple-levels of nested exports have a boolean value for the default export
Globally define require() so that UMD modules which check for the existence of require() to determine if it's CommonJS use the CommonJS code path instead of the globalThis code path. This is not great.
Embed regeneratorRuntime so that modules which expect it to be a global work
Fix crash when loading JS fails really quickly

Begin adding integration tests with snapshots that run with HMR disabled & HMR enabled
Add comment explaining failed package.json parsing optimization
Elaborate on bun bun in the readme
Switch to UTF-8 for prefilled strings, remove eagerly loading identifier_name
Symlinks work but the readme wasn't updated
Add skeleton code for macros but do not execute them yet

Update options.zig
Do not attempt to HMR export {value} from, just assume it will be HMR'd (or not)

Begin to add integration tests
Little more clarify readme
Add puppeteer to package.json

Bun v0.0.16

Switch to 0.0.x instead of 0.0.0-x to fix the npm install issue
write the version
Automatically rewrite TS import paths from .jsx? -> .tsx? when .jsx? is not found

This was already partially implemented but it was returning filenames instead of absolute paths. This matches the behavior from microsoft/TypeScript#4595.
