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:

 * **Binary compatibility** is the ability to compile a program against OkHttp 3.x, and then to run
   it against OkHttp 4.x. We’re using the excellent [japicmp][japicmp] library via its

Remove three old cipher suites and add five new ones. This tracks changes in what's available on
Android and Java, and also what cipher suites recent releases of Chrome and Firefox support by
default.
