Notable changes

Importing JSON modules now requires experimental import assertions syntax

This release adds experimental support for the import assertions stage 3 proposal.

To keep Node.js ESM implementation as compatible as possible with the HTML spec, import assertions are now required to import JSON modules (still behind the --experimental-json-modules CLI flag):

import info from './package.json' assert { type: 'json' };

Or use dynamic import:

const info = await import('./package.json', { assert: { type: 'json' } });
