If you already have WordPress 2.7 or 2.7.1 RC1 installed, you’ll receive an update notification that will allow you to upgrade WordPress from within WP-Admin itself.
You can automatically upgrade from 2.7 to 2.7.1 via the Tools > Upgrade menu. This will upgrade the files and the database as well in one step. Or you can download the package and upgrade manually.
