Since V10_SP12 the ToolScope firmware knows so called feature switches. They are used when implementing new features in the firmware.
The most new features are implemented to be shown only, if a feature switch is enabled. This takes care for the fact that after an update with a new service pack the user interface looks like before the update so that e.g. training slides are not outdated although new features are available. This also takes care that new code, especially in the candidate versions is mostly not executed and can thus not create unwanted side effects, even in the "candidate" versions of ToolScopes.
A change of a feature switch state generally need a partial restart to be activated.
