License
Enter your license key to unlock the Pro features. The status is re-checked from time to time: a temporary network problem never disables Pro abruptly. "Deactivate on this site" frees the license, to move it to another site.
Updates and versions
Updates are always detected. A checkbox lets you install them automatically as soon as they are available (off by default). Below, the history of the published versions lets you go back to a previous version in one click if you ever need to. The history needs an active license.
