{"active":true,"blog_title":"Introducing the Microsoft Fabric Extensibility Toolkit","blog_url":"https://blog.fabric.microsoft.com/en-us/blog/introducing-the-microsoft-fabric-extensibility-toolkit","feature_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.","feature_name":"Fabric Extensibility Toolkit - Variable support","last_modified":"2026-02-09","product_id":"c6da6b3b-ded6-ee11-9079-000d3a310f67","product_name":"Fabric Developer Experiences","release_date":"2026-03-31","release_item_id":"5d62411a-20db-f011-8544-000d3a3740cc","release_status":"Planned","release_type":"Public preview"}
