Checks with Google twice a day if a new ga.js is available and downloads it automaticly. Settings for Analytics for WordPress is automaticly updated to use the locally hosted version.
Locally hosted version have a serialized filename, so browsers will download the new version when available, so you can set a far-future HTTP expires header.
There is no admin panel, everything is automatic.
