+3. commit the change with the message "Update {name} for preview 7" where {name} is the name of the file without the extension.
+4. push the branch to the remote repository.
+5. create a pull request with the title "Update {name} for preview 7" and the body "Please update the release notes here as needed for Preview 7.\n\n/cc @{reviewer}" where {name} is the name of the file without the extension and {reviewer} is assigned based on the assignment table below.

+Create a new folder in the releasenotes/10.0/preview folder for preview7. Inside of it duplicate the folder structure and files that are in the preview6 folder and for each of the files use the following template based on the names of the product that the file is in. You can use the previous file as a reference for the content. Ignore the api-diff folder. Ignore the release.json file.
