We have released an update to the 1.2 BETA that is now available via the Downloads page to license holders. This is a single fix update that improves the integration between Gravity Forms and Justin Tadlock's Members plugin.
If you are a beta testing, this is an optional release. If you run into any issues installing Gravity Forms with the Members plugin that causes Gravity Forms to not appear in the WordPress menus until you add the appropriate capabilities to the Administrator role using the Members plugin, this version patches that issue.
