 ## Changes since v4.0.0
 
+[#258](https://github.com/pusher/oauth2_proxy/pull/258) Add IDToken for Azure provider
+  - This PR adds the IDToken into the session for the Azure provider allowing requests to a backend to be identified as a specific user. As a consequence, if you are using a cookie to store the session the cookie will now exceed the 4kb size limit and be split into multiple cookies. This can cause problems when using nginx as a proxy, resulting in no cookie being passed at all. Either increase the proxy_buffer_size in nginx or implement the redis session storage (see https://pusher.github.io/oauth2_proxy/configuration#redis-storage)
