      Associate each feature flag with the release version for the feature. Enforce that features with default:false have no release version and features with default:true have a release version. version is required to be a string. For example:

      feature_flags:
    featureFlagToaster:
      description: "Make toast"
      cpp_varname: gToaster
      default: false

    featureFlagBlender:
      description: "Make smoothie"
      cpp_varname: gBlender
      default: true
      version: “4.7”

      Provide the helpers:

      feature_flags::gToaster.isEnabled(ServerGlobalParams::FeatureCompatibility::Version)
feature_flags::gToaster.isEnabledAndIgnoreFCV()
feature_flags::gToaster.getVersion() // throws if the feature is not enabled

      For an enabled feature with default:false, getVersion() will return ServerGlobalParams::FeatureCompatibility::kLatest.
