Please be considerate of your servers and their operators as you roll out this release. Compression
saves bandwidth but it costs CPU and memory! If you run into a problem you may need to adjust or
disable the `permessage-deflate` compression settings on your server.

Note that OkHttp won't use compression when sending messages smaller than 1 KiB.

 *  Fix: Don't crash when the URL hostname contains an underscore on Android.

## Version 5.0.0-alpha.11

 *  New: Enable fast fallback by default. It's our implementation of Happy Eyeballs,
    [RFC 8305][rfc_8305]. Disable with `OkHttpClient.Builder.fastFallback(false)`.
 *  Fix: Don't log response bodies for server-sent events.
 *  Fix: Skip early hints (status code 103) responses.
 *  Fix: Don't log sensitive headers in `Request.toString()`.
