release. For example, in OkHttp 2.2 we dropped support for SSL 3.0 in response to the [POODLE](https://googleonlinesecurity.blogspot.ca/2014/10/this-poodle-bites-exploiting-ssl-30.html) attack. And in OkHttp 2.3 we dropped support for [RC4](https://en.wikipedia.org/wiki/RC4#Security). As with your desktop web browser, staying up-to-date with OkHttp is the best way to stay secure.

You can build your own connection spec with a custom set of TLS versions and cipher suites. For example, this configuration...

        // kerberos mech token with ticket for fake service, RC4 service key in keyTab above

                this.masterKey = new byte[16];
                tc.getConfig().getRandom().nextBytes(this.masterKey);

                byte[] encryptedKey = new byte[16];
                Cipher rc4 = Crypto.getArcfour(userSessionKey);
                rc4.update(this.masterKey, 0, 16, encryptedKey, 0);
                setEncryptedSessionKey(encryptedKey);
            }
            else {
                this.masterKey = userSessionKey;

 *  **HTTP/2 support.** We've done interop testing and haven't seen any
    problems. HTTP/2 support has been a big effort and we're particularly
    thankful to Adrian Cole who has helped us to reach this milestone.

 *  **RC4 cipher suites are no longer supported by default.** To connect to
    old, obsolete servers relying on these cipher suites, you must create a
    custom `ConnectionSpec`.
