xPC Target Support for NI X series PCIe-63XX DAQs

Have there been any developments in Matlab support for PCIe DAQ boards? It appears that xPC target still only supports Humusoft MF634 and the outdated NI PCIe-6259 DAQ cards despite the fact that there are now many PCIe DAQs available on the market, including the NI X series PCIe-63XX DAQs.
