 *   The command line `--require` flag now properly handles filenames or module names that are invalid identifiers (like an NPM module with a hyphen in the name).
 *   `Object.assign`, output when object destructuring is used, is polyfilled using the same polyfill that Babel outputs. This means that polyfills shouldn’t be required unless support for Internet Explorer 8 or below is desired (or your own code uses a feature that requires a polyfill).

+*   Dynamic `import()` expressions are now supported. The parentheses are always required, to distinguish from `import` statements. See [Modules](#dynamic-import). Note that as of this writing, the JavaScript feature itself is still Stage 3; if it changes before being fully standardized, it may change in CoffeeScript too. Using `import()` before its upstream [ECMAScript proposal](https://github.com/tc39/proposal-dynamic-import) is finalized should be considered provisional, subject to breaking changes if the proposal changes or is rejected. We have also revised our [policy](#contributing) on Stage 3 ECMAScript features, to support them when the features are [shipped](https://caniuse.com/#feat=es6-module-dynamic-import) in significant runtimes such as major browsers or Node.js.
+*   There are now two browser versions of the CoffeeScript compiler: the traditional one that’s been published for years, and a new [ES module version](/browser-compiler-modern/coffeescript.js) that can be used via `import`. If your browser supports it, it is in effect on this page. A reference to the ES module browser compiler is in the `package.json` `"module"` field.
+*   The Node API now exposes the previously private `registerCompiled` method, to allow plugins that use the `coffeescript` package to take advantage of CoffeeScript’s internal caching.
+*   Bugfixes for commas in strings in block arrays, a reference to `@` not being maintained in a `do` block in a class, and function default parameters should no longer be wrapped by extraneous parentheses.

This option outputs an “abstract syntax tree,” or a JSON-like representation of the input CoffeeScript source code. This AST follows [Babel’s spec](https://github.com/babel/babel/blob/master/packages/babel-parser/ast/spec.md) as closely as possible, for compatibility with tools that work with JavaScript source code. Two tools that use this new AST output are [`eslint-plugin-coffee`](https://github.com/helixbass/eslint-plugin-coffee), a plugin to lint CoffeeScript via [ESLint](https://eslint.org/); and [`prettier-plugin-coffeescript`](https://github.com/helixbass/prettier-plugin-coffeescript), a plugin to reformat CoffeeScript source code via [Prettier](https://prettier.io/). _The structure and properties of CoffeeScript’s AST are not final and may undergo breaking changes between CoffeeScript versions; please [open an issue](https://github.com/jashkenas/coffeescript/issues) if you are interested in creating new integrations._
