+## Unreleased
+
+* 💥 Rework the list of variants to have more modern defaults.
+  The table below shows how to upgrade your v3 import to their equivalent v4 import.
+  See the [migration guide](https://github.com/MattiasBuelens/web-streams-polyfill/blob/v4/MIGRATING.md) for more information.
+  ([#82](https://github.com/MattiasBuelens/web-streams-polyfill/issues/82), [#139](https://github.com/MattiasBuelens/web-streams-polyfill/pull/139))
+* 💥 Remove the ES2018 variant, in favor of the ES2015 variant.
+* 💥 Switch to [subpath exports](https://nodejs.org/api/packages.html#subpath-exports) for variants.
+  * Node 12 or higher is required to `import` or `require()` a variant.
+  * When using TypeScript, version 4.7 or higher is now required. Additionally, [`moduleResolution`](https://www.typescriptlang.org/tsconfig#moduleResolution) must be set to `"node16"`, `"nodenext"` or `"bundler"`.
+* 🚀 Support [importing as ESM in Node](https://nodejs.org/api/esm.html).
+* 💅 Minify all code in the published package, to reduce the download size.
