* **Breaking** bugfixes
* Always include suffix if private suffix enabled and private suffix exists ([300](https://github.com/john-kurkowski/tldextract/issues/300))
* Add a 4th field `is_private: bool`, to the `ExtractResult`
`namedtuple`, indicating whether the extraction came from the PSL's
private domains or not.
* **This could cause issues when iterating over the tuple and assuming
only 3 fields.**
* Previously, the docs promoted iteration to rejoin parts of the tuple.
This is better achieved by individual access of fields of interest
(e.g. `ExtractResult.subdomain`) or convenience properties (e.g.
`ExtractResult.{fqdn,registered_domain}`).
