Feature - RequirementType

Features can now declare a RequirementType. The default RequirementType is Any, which means if any of it's filters evaluate to true, then the feature will be enabled. Declaring a RequirementType of All means that every filter must evaluate to true in order for the feature to be enabled. Added in #221.

"FeatureW": {
    "RequirementType": "All",
    "EnabledFor": []
}

Targeting Exclusion

Targeting filters define an Audience. Now, Audiences can be fine tuned to exclude certain users and groups. By adding an Exclusion to an Audience, targeting filters will evaluate to false for users that are either directly defined, or a part of a group that is defined within the Exclusion. This takes priority over any other section of the Audience. Added in #218.

"Exclusion": {
    "Users": [
        "Mark"
    ],
    "Groups": [
        "Admins"
    ]
}
