New firmware installed in Lorex NVR yesterday

Yesterday there was a message on my 4K Lorex 16 channel NVR that new firmware was available. I installed it. yet, I see no documentation what actually was addressed. What exactly did this new firmware address? Does anybody know what this new firmware did? --Greg--
 
same here, NVR LNR6100 stated update firmware but there is no info on what they updated. Cant see anything new in the menus either... Also, i have contacted them numerous times for the camera firmware for LNB8005 series and they state there is no firmware update for them...which i find hard to believe.
