Bug: Build artifact at Beta 6 is different from `npm run build`

// `npm run build` output dist/index.cjs

'use strict';

exports = module.exports = fetch;

function fetch(url, options_) { 
// ...
}

vs

// published 3.0.beta-6 dist/index.cjs
'use strict';

exports = module.exports = fetch;

const fetch = (url, options_) => {
// ..
}
//

Not sure if there is an extra pre-publishing step performed, but as a result beta.6 is completely broken.

@xxczaki the issue wasn’t related to Rollup - it can export as an arrow function. The problem was that by changing from a function to const you break the hoisting, so, fetch becomes undefined on top of the file.

That was a huge PR, changing across 12 files and merged after just one approval - we should set policy on that…
