+## Breaking change
+
+This update removes the previously deprecated component documentation for **cyclebutton**, **quickaction**, **searchwithin**, and **splitbutton**.
+
+To support the Spectrum 2 (S2) Foundations release, Storybook has been updated to toggle token packages to connect the following labels with their appropriate data sources:
+
+- **Spectrum 1**: Flagged as the "legacy" context, this version is no longer the default for the component contexts. When selected, Storybook will load the `@spectrum-css/tokens` at release `v14.6.0` and attach the `.spectrum--legacy` class to the container.
+- **Spectrum 2**: The new default context, this version represents the "S2 Foundations" release which serves as a bridge between S1 and S2. Components in this context are not fully S2 and will not exactly match specifications but they do reflect a significant move toward the S2 designs. For full details, see the token and component-level changelogs.
+- **Express**: This now deprecated context is still rendered in Storybook by leveraging the `@spectrum-css/tokens` at release `v14.6.0`. Please note that Express and S1 will be removed in the next major release.
+
+This release also includes:
+
+- New migration documentation for S1 -> S2 updates
+- Fix for the duplicate line numbers in the code preview plugin
+- Updated styles to integrate Spectrum styling into the Storybook UI

+## Breaking change
+
+This major update creates a bridge between the Spectrum 1 (S1) and Spectrum 2 (S2) designs, dubbed "Spectrum 2 Foundations". These do _NOT_ reflect a fully migrated S2 component. This approach allows consumers to swap the appearance of their components between S1, Express, and S2 by leveraging a "system" layer that remaps the necessary component-level tokens to the appropriate token dataset.
+
+For these components to appear S2, you must load the assets with the `@spectrum-css/tokens` at `v16` or higher.
+
+For S1 or Express, load assets with the `@spectrum-css/tokens` at `v14.x` or `v15.x`.
+
+If you are looking to implement a fully S2 design, please explore the `next` tag releases instead of using this foundations release. **This release is used in Spectrum Web Components 1.x**.
+
+### Deprecations
+
+The `metadata` folder containing the `mods.md` and `metadata.json` assets has been removed from source. To find information about the components including what selectors, modifiers, and passthroughs are used, please see the `dist/metadata.json` asset shipped with every component containing CSS.
+
+The `index-vars.css` asset has been removed in this release as it was previously deprecated and is no longer maintained. Please use the `index.css` or `index-base.css`
+
+### File usage
+
+If you are rendering components and need **only** the S2 Foundations styles, you can make use of the `index.css` asset which contains all the base styles plus the system mappings for S2 Foundations.
+
+If you are using this version to publish **only** an S1 or Express component, you can use the `index-base.css` plus the desired `themes/(spectrum|express).css` file.
+
+To render a component that can be easily swapped between the S2 Foundations, S1, or Express contexts, load `index-base.css` with the `index-theme.css` file and leverage the appropriate context classes (`.spectrum--legacy` for S1 and `.spectrum--express` for Express).
