Respond to deprecations

Fields defined in the Real-time Curation specification can be deprecated, which is announced in the release notes, and indicated in the reference documentation with the following statement in the first line of the field's description:

    Deprecated. This will be removed in {MONTH}, {YEAR}.

After the deprecation period passes, these fields sunset, meaning that they are removed from the specification. Sunset fields aren't sent in the SegmentRequest, and are ignored if you include them in your SegmentResponse.

During the deprecation period, update your integration to remove any logic dependent on deprecated fields to avoid interruptions to your Real-time Curation integration.
