## Version 3.14.2

_2019-05-19_

 *  Fix: Lock in a route when recovering from an HTTP/2 connection error. We had a bug where two
    calls that failed at the same time could cause OkHttp to crash with a `NoSuchElementException`
    instead of the expected `IOException`.

 *  Fix: Don't crash with a `NullPointerException` when formatting an error message describing a
    truncated response from an HTTPS proxy.
