 *  **Cipher suites may now have arbitrary names.** Previously `CipherSuite` was
    a Java enum and it was impossible to define new cipher suites without first
    upgrading OkHttp. With this change it is now a regular Java class with
    enum-like constants. Application code that uses enum methods on cipher
    suites (`ordinal()`, `name()`, etc.) will break with this change.
