### 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:

```
Caused by: javax.net.ssl.SSLProtocolException: SSL handshake aborted: ssl=0x7f2719a89e80:

     * followed by those lines.
     *
     * HTTPS responses also contain SSL session information. This begins with a blank line, and then
     * a line containing the cipher suite. Next is the length of the peer certificate chain. These
     * certificates are base64-encoded and appear each on their own line. The next line contains the

      ConnectionSpec.Builder(ConnectionSpec.MODERN_TLS)
        .cipherSuites(*arrayOf<CipherSuite>())
        .build()
    }.also { expected ->
      assertThat(expected.message)
        .isEqualTo("At least one cipher suite is required")
    }
  }

  @Test
  fun cleartextBuilder() {
    val cleartextSpec = ConnectionSpec.Builder(false).build()
    assertThat(cleartextSpec.isTls).isFalse()
  }

  @Test

 *  New: Buffer WebSocket frames for better performance.
 *  New: Drop support for `TLS_DHE_DSS_WITH_AES_128_CBC_SHA`, our only remaining
    DSS cipher suite. This is consistent with Firefox and Chrome which have also
    dropped these cipher suite.

## Version 2.5.0

_2015-08-25_

 *  **Timeouts now default to 10 seconds.** Previously we defaulted to never

class HostnameVerifierTest {

  @Test fun verify() {
    val session = FakeSSLSession()

 *  New: Prefer the client's configured precedence order for TLS cipher suites. (OkHttp used to
    prefer the JDK’s precedence order.) This change may cause your HTTP calls to negotiate a
    different cipher suite than before! OkHttp's defaults cipher suites are selected for good
    security and performance.

 *  New: `ConnectionListener` publishes events for connects, disconnects, and use of pooled
    connections.
