-**ATTENTION:** As of Prebid.js v4.14.0, ID5 requires `storage.type` to be `"html5"` and `storage.name` to be `"id5id"`. Using other values will display a warning today, but in an upcoming release, it will prevent the ID5 module from loading. This change is to ensure the ID5 module in Prebid.js interoperates properly with the [ID5 API](https://github.com/id5io/id5-api.js) and to reduce the size of publishers' first-party cookies that are sent to their web servers. If you have any questions, please reach out to us at [prebid@id5.io](mailto:prebid@id5.io).
