+* A client implementing `psr/http-client-implementation` is required.
+  To upgrade your application (default install) switch from guzzle 6 to guzzle 7 (or replace `php-http/guzzle6-adapter` with any `psr/http-client-implementation`), see the install instructions in the [README file](README.md)
+* All previous deprecated code in version 2 is removed.
+* The following classes are now final
+    * `Github\HttpClient\Message\ResponseMediator`
+    * `Github\HttpClient\Plugin\Authentication`
+    * `Github\HttpClient\Plugin\GithubExceptionThrower`
+    * `Github\HttpClient\Plugin\History`
+    * `Github\HttpClient\Plugin\PathPrepend`
+
+### Authetication methods
+
+* `Github\Client::AUTH_URL_TOKEN` use `Github\Client::AUTH_ACCESS_TOKEN` instead.
+* `Github\Client::AUTH_URL_CLIENT_ID` use `Github\Client::AUTH_CLIENT_ID` instead.
+* `Github\Client::AUTH_HTTP_TOKEN` use `Github\Client::AUTH_ACCESS_TOKEN` instead.
+* `Github\Client::AUTH_HTTP_PASSWORD` use `Github\Client::AUTH_ACCESS_TOKEN` instead.
