 *  Fix: Don't crash in `HeldCertificate.Builder` when creating certificates on older versions of
    Android, including Android 6. We were using a feature of `SimpleDateFormat` that wasn't
    available in those versions!


## Version 4.8.0

## Retrying Requests

Sometimes connections fail: either a pooled connection was stale and disconnected, or the webserver itself couldn’t be reached. OkHttp will retry the request with a different route if one is available.
