Version 3.0.0

Major

• Updated Node.js support to ^12.22.0 || ^14.17.0 || >= 16.0.0.
• Updated dev dependencies, some of which require newer Node.js versions than previously supported.
• Public modules are now individually listed in the package files and exports fields.
• Removed ./package from the package exports field; the full package.json filename must be used in a require path.
• Removed the package main index module; deep imports must be used.
• Shortened public module deep import paths, removing the /public/.
• The API is now ESM in .mjs files instead of CJS in .js files, accessible via import but not require.
• Now uses React.createElement instead of the the new React JSX runtime.

Patch

• Also run GitHub Actions CI with Node.js v17.
• Simplified package scripts.
• Avoid named imports from react and react-dom as they’re not proper Node.js ESM.
• Removed conditionality on the Node.js global process.env.NODE_ENV.
• Error messages are now more detailed.
• Reorganized the test file structure.
• Renamed imports in the test index module.
• Test the bundle sizes for public modules individually.
• Use a new assertBundleSize function to assert module bundle size in tests:
  • Failure message contains details about the bundle size and how much the limit was exceeded.
  • Errors when the surplus is greater than 25% of the limit, suggesting the limit should be reduced.
  • Resolves the minified bundle and its gzipped size for debugging in tests.
• Configured Prettier option singleQuote to the default, false.
• Documentation tweaks.
• Amended the changelog entry for v2.0.0.
