 THE PLACE= key is gone. It can be replaced by an ID= for a long time, cause
 we walk up the chain of physical devices to find a match.
 
+The KEY="<value>" format supports '=', '==', '!=,' , '+=' now. This makes it
+easier to skip certain devices without composing rules with weird character
+class negations like:
+  KERNEL="[!s][!c][!d]*"
+
+this can be replaced by:
+  KERNEL!="scd*"
+
+The simple '=' is still supported, but the rules should be converted if
+possible, to be better human-readable.
