2.9.8 Log Entrys

ever since i upgraded to 2.9.8 from 2.8.x i am getting some log entrys that i cant figure out.

Hotspot debug: hs-ether2 new host detected 00:83:da:34:78/172.20.0.10

Hotspot debug: dynamic host added (mac address) (ip address)

Hotspot debug: dynamic host removed


Lots of stuff like that. Why is this happening? its kinda annoying
I know that the mac addresses are switches on my network.


Thank you
