Which the default value of the parameter "XFeatures" in last release NB?
The default values for this setting, shown in the manual and present in the server settings, are the opposite of each other.

In manual shown the checkbox "Disable XFeatures"
In last release i see the checkbox "Enable XFeatures"

Which is true? And does it match the description?
