A special Blueprint that continues to affect any page that uses it.

A 'live' Blueprint is a special Page Blueprint in which its form 'persists' to any page where this Blueprint is activated. This means that with a Live Blueprint you can make a change to the original Blueprint and any of the pages on which it is used (it's 'offspring') will also see the change. In this way, there is a persistent and 'live' connection from the offspring back to the source Blueprint. 

This 'live' connection is what makes a Live Blueprint different from a Page Blueprint or Space Blueprint. These latter two can be thought of as the 'stamp' from which copies can be 'stamped out'. Changes to the 'stamp' will only affect future copies. Whereas a Live Blueprint, by contrast, might best be thought of as a 'link' or a 'reference'. Changes to the source Blueprint automatically update in any place it is referenced.

Like Page Blueprints and Space Blueprints, though, you are able to use substitution fields in your Live Blueprint. Indeed, that's what makes them particularly valuable (and quite different from Confluence's 'Include Page' macro).

Live Blueprints are not accessible from the Blueprints Menu. They are only able to be 'used' or 'activated' on a page with the Live Blueprint Macro.

Live Blueprints were introduced with Blueprint Maker version 2.0+. An additional property was added to the JSON File, called "type" which allows users to specify the value "live" if they want this Blueprint to act as a Live Blueprint.
