 ## What's new in V7
 
+The V7 edition of the action includes:
 - Migrated action internals to ESM for compatibility with latest `@actions/*` packages. No changes to action inputs, outputs, or behavior.
 
-### Breaking change
-
-- The dummy `NODE_AUTH_TOKEN` fallback has been removed, as it could unintentionally affect the generated `.npmrc` with a non-functional token. With this change, if `registry-url` is set without `NODE_AUTH_TOKEN`, legacy Yarn Classic (1.x) and older Node/npm versions may fail, and pnpm may warn. npm Trusted Publishing (OIDC) is not affected, since it does not use `NODE_AUTH_TOKEN`.
-
 ## Breaking changes in V6
 
 - Caching is now automatically enabled for npm projects when either the `devEngines.packageManager` field or the top-level `packageManager` field in `package.json` is set to `npm`. For other package managers, such as Yarn and pnpm, caching is disabled by default and must be configured manually using the `cache` input.

 See [supported version syntax](https://github.com/actions/setup-node#supported-version-syntax).
 
-> The action resolves a relative `node-version-file` path against `GITHUB_WORKSPACE`, which is the repository root by default. If the input is a full absolute path, the action uses that path directly instead of appending it to the workspace.
