Hi, all Multiple cells (Nova-Cells-v2) is supported in Pike release. It is necessary to confirm that existing APIs work appropriately in the multiple cells environment. We will post multiple patches, so I created BluePrint[1] to make it easier to keep track of those patches. Please check the contents and approve it.
