One carryover rule in Retro Snapshot
Retro Snapshot now counts carryover the same way as Dashboard and Sprint Summary, for the sprint you pick and for the sprints it compares with. Figures can move, and many will read lower, because the share is now of every item in the sprint.
While a sprint is running
Carryover shows a dash until the sprint finishes, as it does in your other views.
Better with assistive technology
Screen readers now announce the project and team you have selected. Voice control can reach the pickers and the account menu by the text you see on screen.
What you need to do
Nothing. Azure DevOps updates the extension automatically. Open Retro Snapshot and generate a snapshot for a finished sprint to see the new figures.
