<!-- NEW RELEASE NOTES ENTRY -->


# v1.15.9

    // We extract the diagonals from k[0] up to and including k[1].
    // Addressing is 0 for the main diagonal. (So k = [0, 0] would just extract
    // the main diagonal). It's negative for subdiagonals (under and to the left
    // of the main diagonal) and positive for superdiagonals (above and to the
    // right of the main diagonal).

- Supporting Cross RG resources (disks, Azure File and node [Experimental]

Besides the above new features, support for Azure Virtual Machine Scale Sets (VMSS) and Cluster-Autoscaler is now stable and considered GA:

- Azure virtual machine scale sets (VMSS) allow you to create and manage identical load balanced VMs that automatically increase or decrease based on demand or a set schedule.
