## Version 4.9.0

_2020-09-11_

**With this release, `okhttp-tls` no longer depends on Bouncy Castle and doesn't install the
Bouncy Castle security provider.** If you still need it, you can do it yourself:

```
Security.addProvider(BouncyCastleProvider())
```

        )
      },
      construct = {
        Validity(
          notBefore = it[0] as Long,
          notAfter = it[1] as Long,
        )
      },
    )

  /** The type of the parameters depends on the algorithm that precedes it. */
  private val algorithmParameters: DerAdapter<Any?> =
    Adapters.usingTypeHint { typeHint ->
      when (typeHint) {

  }
}
```

Further examples are on the [OkHttp Recipes page][recipes].


Requirements
------------

OkHttp works on Android 5.0+ (API level 21+) and Java 8+.

OkHttp depends on [Okio][okio] for high-performance I/O and the [Kotlin standard library][kotlin]. Both are small libraries with strong backward-compatibility.

    initialize the response cache.
 *  New: Fold `MockWebServerRule` into `MockWebServer`. This makes it easier to
    write JUnit tests with `MockWebServer`. The `MockWebServer` library now
    depends on JUnit, though it continues to work with all testing frameworks.
 *  Fix: `FormEncodingBuilder` is now consistent with browsers in which
    characters it escapes. Previously we weren’t percent-encoding commas,

| com.squareup.okhttp3:mockwebserver3-junit5:5.0.0-alpha.2 | mockwebserver3.junit5 | Optional JUnit 5 integration.     |
| com.squareup.okhttp3:mockwebserver:5.0.0-alpha.2         | okhttp3.mockwebserver | Obsolete. Depends on JUnit 4.     |

The new APIs use `mockwebserver3` in both the Maven coordinate and package name. This new API is
**not stable** and will likely change before the final 5.0.0 release.

    .connectionSpecs(Collections.singletonList(spec))
    .build();

### Debugging TLS Handshake Failures

The TLS handshake requires clients and servers to share a common TLS version and cipher suite. This
depends on the JVM or Android version, OkHttp version, and web server configuration. If there is no
common cipher suite and TLS version, your call will fail like this:

```
