I have a Dell N3248PXE-ON switch which I love it is very fast.  I am currently on 6.7.0.4. There is a 6.7.1.1 that came out Oct 18th 2021. Of coarse there was a 6.6.3.17 that came out Oct 22nd 2021 4 days after not sure why a smaller version came out after the newest one so a little confused on which one to use.   [IMAGE]
Firmware version why is there a lower number one that came out after a higher.
