FMD Release Highlights – April 2026
Month: April 2026
🔐 Workspace Identity Support for Notebook Activities
With Microsoft Fabric now supporting Workspace Identity in Notebook activities, the FMD Framework has been enhanced to fully align with this model.
Previously, the Workspace Identity used by Notebook activities did not automatically have access to the Data workspace, potentially causing authorization issues during execution.
What’s new?
The Workspace Identity is now explicitly granted access to the Data workspace, ensuring that metadata‑driven pipelines can execute securely without additional manual permission steps.
This enables a cleaner, more secure identity setup that matches modern Fabric best practices.
🛠️ Fix for SCD2 Logic in the Silver Notebook
A rare but critical edge case was identified in the Silver Notebook SCD2 process:
- Records that were deleted
- And later reintroduced with updated data
- Were not always recognized correctly as new versions
This has now been fixed.
The SCD2 logic correctly handles delete‑and‑reinsert scenarios, ensuring accurate historical tracking and reliable slowly changing dimension behavior.
⚡ Reliable Queueing for Parallel Dev & Prod Loads
Running Development and Production loads in parallel surfaced an issue where the queuing mechanism did not behave as expected.
Root cause:
The queueing process lacked workspace-level isolation.
Fix implemented:
The Data Workspace GUID is now explicitly passed as an input parameter.
This guarantees proper separation of Dev and Prod workloads, resulting in deterministic and predictable execution behavior when environments run concurrently.

== 201 or 202 → in (201, 202)
Branding
I also worked with help of AI on the branding, so you will see as of today some new logo's. Please let me know your thought.
Documentation & Wiki Updates
The April release also includes updated documentation and Wiki pages:
- Notebook behavior now aligned with the latest fixes
- Improved explanations around identity, queueing, and execution patterns
- Content refined based on practical implementation feedback
✔️ Summary
The April FMD Framework release is all about making the framework more production‑ready:
- Secure Workspace Identity integration
- Correct and resilient SCD2 behavior
- Reliable parallel Dev/Prod execution
- Stronger error handling across all core notebooks
- Cleaner templates and safer demo data handling
- Improved and up‑to‑date documentation
These improvements further strengthen FMD as a platform‑engineering foundation for Microsoft Fabric.
