Just wondering when the firmware for the ZEN71 v3 hardware will be updated to include:

- Updated SDK from 7.19.3 to 7.24.1

As was done on all the other 800 series switches. It’s the last one I have on the older library.

Updated six ZEN71s to 3.80. All seem to be working fine with the update. Now all my 800 series devices have the new library. Thanks!
