Applying Updates to Drupal Core on Pantheon with Drush
One of the great things about the Pantheon platform is that it provides a very easy way to apply updates to your Drupal sites. All that you need to do is navigate to the dashboard for your site, and if there have been any new releases for Drupal core, you will be able to see an "Apply Updates" button. Just click this button, and you'll be ready to run some tests and deploy to production.
