Version 3.0.0

Major

• Updated Node.js support to ^12.20 || >= 14.13.
• Updated dev dependencies, some of which require newer Node.js versions than were previously supported.
• Added a package exports field.
• The API is now ESM in .mjs files instead of CJS in .js files, accessible via import but not require.

Minor

• Added package sideEffects field.

Patch

• Stop using hard-rejection to detect unhandled Promise rejections in tests, as Node.js v15+ does this natively.
• Simplified the package scripts now that jsdoc-md v10 automatically generates a Prettier formatted readme.
• Updated GitHub Actions CI config:
  • Also run tests with Node.js v16.
  • Updated actions/checkout to v2.
  • Updated actions/setup-node to v2.
  • Don’t specify the CI environment variable as it’s set by default.
• Use Promise.all for faster tests.
• Tweak whitespace formatting.
• Readme tweaks.
