When Ingage releases a new feature that out paces a previous one, the previous feature is considered "Legacy." Like a "Legacy Page" or a "Legacy Button."
Examples include:
Moving from Layout Pages to Freestyle pages, allowing you the control of what and where content lives on a page
Changing from Buttons to Freestyle actions, allowing for clickability to be applied to most objects on a page
Expanding from "Media" and "Read Me" buttons to the Pop up Action, bringing Freestyle capabilities to pop up windows
Out of date pages will be denoted on the Storyboard of your presentation by a blue dot on the upper right of the page thumbnail, and when opening the page to edit can be automatically updated via a pop up message.
Out of date components on a page will be identifiable by a dialogue box in the lower right corner when editing the page, and can be updated via this dialogue box.
