Version 1.4.6 release notes

We are now exposing two new data elements as part of the Title representation: asin and customSubjectCategory. Both have also been added to the product display view which many people use.

        "asin": "0139615326",
        "customSubjectCategory": "Occult Sciences",
        "otherFields": {

You can also use customSubjectCategory as a filter parameter.
