Low memory hardware status
  Now that there is a new version OS that I had heard takes up less space. Is this still a problem with the hardware that is listed as   "AREDN Stable, but, NOT recommended for new deployments.  (Low memory or non-MIMO device" in https://www.arednmesh.org/content/supported-platform-matrix ?

non-MIMO devices
Dan, because the newer releases have a somewhat smaller footprint, it'll be easier to get them installed in the older 32MB devices.   However, it's still not recommended to run non-MIMO devices in a MIMO environment.  Because MIMO devices are dual-polarity, they put half their total power in each antenna.  That means a non-MIMO device (single-polarity) will only receive half the power from the MIMO device.  That's an automatic 3 dB SNR penalty.
