 The command will create a new markdown file in the `.changeset` directory with your changes.
 
+## Important: @swc/core and component updates
+
+When making changes to `@swc/core`, you **must** also include the corresponding `@spectrum-web-components` component in the same changeset to ensure the changes appear in the component's changelog. This is because `@swc/core` changes are internal and don't automatically propagate to the component changelogs.
+
+**Best practice**: Create a single changeset that includes both packages when updating core functionality that affects a specific component.

 ## Example Changeset
 
 A typical changeset file looks like this:
 
 ```markdown
 ---
+'@swc/core': patch
 '@spectrum-web-components/button': minor
 '@spectrum-web-components/theme': patch

--   **Added**: Added new variant `tertiary` to `<sp-button>` component [#9999](https://github.com/adobe/spectrum-web-components/pull/9999)
--   **Fixed**: Fixed `<sp-theme>` theme compatibility issues [#10000](https://github.com/adobe/spectrum-web-components/pull/10000)
