TLS Configuration History
=========================

OkHttp tracks the dynamic TLS ecosystem to balance connectivity and security. This page is a log of
changes we've made over time to OkHttp's default TLS options.

[OkHttp 3.14][OkHttp314]
------------------------

_2019-03-14_

Remove 2 TLSv1.3 cipher suites that are neither available on OkHttp’s host platforms nor enabled in releases of Chrome and Firefox.

=====================

OkHttp 4.x upgrades our implementation language from Java to Kotlin and keeps everything else the
same. We’ve chosen Kotlin because it gives us powerful new capabilities while integrating closely
with Java.

We spent a lot of time and energy on retaining strict compatibility with OkHttp 3.x. We’re even
keeping the package name the same: `okhttp3`!

There are three kinds of compatibility we’re tracking:
