*
 * This example shows the single instance with default configurations.
 *
 * ```java
 * public final OkHttpClient client = new OkHttpClient.Builder()
 *     .readTimeout(1000, TimeUnit.MILLISECONDS)
 *     .writeTimeout(1000, TimeUnit.MILLISECONDS)
 *     .build();
 * ```
 *
 * This example shows a call with a short 500 millisecond read timeout and a 1000 millisecond

## Version 5.2.1

_2025-10-09_

 *  Fix: Don't crash when calling `Socket.shutdownOutput()` or `shutdownInput()` on an `SSLSocket`
    on Android API 21 through 23. This method throws an `UnsupportedOperationException`, so we now
    catch that and close the underlying stream instead.

 *  Upgrade: [Okio 3.16.1][okio_3_16_1].
