##### RESTRICTED_TLS versions

 * TLSv1.2

[OkHttp 3.10][OkHttp310]
------------------------

_2018-02-24_

Remove two rarely-used cipher suites from the default set. This tracks a [Chromium change][chromium_change] to remove these cipher suites because they are fragile and rarely-used.

##### MODERN_TLS / COMPATIBLE_TLS cipher suites

 * TLS_ECDHE_ECDSA_WITH_AES_128_GCM_SHA256
 * TLS_ECDHE_RSA_WITH_AES_128_GCM_SHA256

 * `CLEARTEXT` is an insecure configuration that is used for `http://` URLs.

These loosely follow the model set in [Google Cloud Policies](https://cloud.google.com/load-balancing/docs/ssl-policies-concepts). We [track changes](../security/tls_configuration_history.md) to this policy.

#### Internal API changes

The `okhttp3.internal` package is not a published API and we change it frequently without warning.
Depending on code in this package is bad and will cause you problems with any upgrade! But the 4.x
will be particularly painful to naughty developers that import from this package! We changed a lot
to take advantage of sweet Kotlin features.
