I hope this is in the right place. It's system related, being about hardware monitoring with the Thermal Monitoring Widget on KF5.

After upgrading from 5.8.5 to 5.8.6, the thermal sensors on my MB and CPU have disappeared from the thermal monitoring widgets' lists, so those temperatures are no longer displayed. I am using PCLInuxOS on:
AMD FX 8350
GA-970A-DS3P (Rev 2.0)
Asus EN210 (Nvidia) GPU
Maxtor STM325031
3 SSDs
Amilo LSL 3220T monitor.

The packages upgraded were:

Installed the following packages:
lib64shapelib2 (1.4.0-1pclos2017)
lib64x265_102 (2.2-1pclos2017)

which don't seem to include anything vaguely related to sensors in the few non-KDE components, leaving suspicion firmly on the KDE packages. I hoped to report a bug, but which component? Nothing stands out as the obvious cause, so I don't know how to set about tracking the problem down. For completeness, here are before and after pictures of the displayed temperatures (OK, I suspect a couple of them are voltages being read as temperatures, but that doesn't change the fact they're now missing)!

Replying to myself... copying the previous version of ksysguardd back to my install fixed this problem. (Don't know what others it's introduced, of course!)
