Description

Items built with the Fabric Extensibility Toolkit can now pick up and resolve Variables, allowing them to dynamically adapt to the context in which they run. When a user opens an Item, the Item automatically evaluates any referenced Variables--such as workspace metadata, user-provided parameters, or environment-specific values--and replaces them with their resolved results. This enables Items to behave consistently across different workspaces and scenarios, while still responding to variable-driven configuration.
