 To create a new stable version, you will need to follow these steps:
 
 1. Run the "create stable version" action.
-1. Pull down the branch that that was created by the GitHub action (it should have the name `changeset-release/{{BRANCH_NAME}}`). Instead of the patch version changes that were made by the action, update the version of all packages manually to be the first patch release of a new version range. For example, if you are creating a `2025-01` API version, you will set the package versions of all packages to `2025.1.0`. Apply this change to `packages/ui-extensions/package.json`, `packages/ui-extensions/CHANGELOG.md`, `packages/ui-extensions-react/package.json`, and `packages/ui-extensions-react/CHANGELOG.md`.
-   > Note: do not update the root-level `package.json`.
+1. Verify that the versions in the package.json and changelog.md files in packages/ were updated correctly. Make sure you get the PR reviewed by one other member of the [UI Extension Stewards GitHub team](https://github.com/orgs/Shopify/teams/ui-extension-stewards).
 1. Push your new changes, and make sure you get the PR reviewed by one other member of the [UI Extension Stewards GitHub team](https://github.com/orgs/Shopify/teams/ui-extension-stewards).
 1. Merge the PR, and let robots release the new versions to NPM and tag it appropriately.
 1. For any changes from `unstable` that have been incorporated into the new version, delete their changeset files on the `unstable` branch and replace the existing `CHANGELOG.md` files in `unstable` with what was just shipped.
