Just upgraded to 20.7 from 20.1.9 with the small intermediate patch, and all went without any issues so far.
The only odd thing I have noticed so far is that this is being logged direct to the screen console:
2020-07-31T16:06:53 lighttpd[74700]: 192.168.1.18 bart.mydomain.com - [31/Jul/2020:16:06:53 +0200] "GET /api/diagnostics/interface/getArp HTTP/1.1" 200 6006 "-" "python-requests/2.24.0"
As well as to the Web GUI log.
Any ideas?
