## Version 3.9.1

_2017-11-18_

 *  New: Recover gracefully when Android's DNS crashes with an unexpected
    `NullPointerException`.
 *  New: Recover gracefully when Android's socket connections crash with an
    unexpected `ClassCastException`.
 *  Fix: Don't include the URL's fragment in `encodedQuery()` when the query
    itself is empty.

## Version 3.9.0
