 - **Added**
   - Added export requirements sections to all Power BI report documentation pages to clarify which Cost Management exports are needed for each report.
   - Added Azure Resource Graph as an explicit requirement for governance and workload optimization reports.
+  - Added `CapacityReservationId` and `CapacityReservationStatus` columns in storage-based Power BI reports ([#1836](https://github.com/microsoft/finops-toolkit/issues/1836)).
 - **Fixed**
   - Fixed tag expansion when tag names contain special characters like colons.
   - Fixed unattached disks count in the workload optimization report to show only truly unattached disks ([#1896](https://github.com/microsoft/finops-toolkit/issues/1896)).
