 been done in order to avoid the damage an attacker can do if the secret
 key is leaked.  When you upgrade you will notice two major changes: all
 sessions that were issued before the upgrade are invalidated and you can
-only store a limited amount of types in the session.  There are two ways
-to avoid these problems on upgrading:
-
-Automatically Upgrade Sessions
-``````````````````````````````
-
-The first method is to allow pickle based sessions for a limited amount of
-time.  This can be done by using the
-:class:`~flask.sessions.UpgradeSecureCookieSession` session
-implementation::
-
-    from flask import Flask
-    from flask.sessions import UpgradeSecureCookieSessionInterface
-
-    app = Flask(__name__)
-    app.session_interface = UpgradeSecureCookieSessionInterface
-
-For as long as this class is being used both pickle and json sessions are
-supported but changes are written in JSON format only.
-
-Revert to Pickle Sessions
-`````````````````````````

-You can also revert to pickle based sessions if you want::
-
-    import pickle
-    from flask import Flask
-    from flask.sessions import SecureCookieSession, \
-         SecureCookieSessionInterface

-    class PickleSessionInterface(SecureCookieSessionInterface):

-            serialization_method = pickle

-    app = Flask(__name__)
-    app.session_interface = PickleSessionInterface

-If you want to continue to use pickle based data we strongly recommend
-switching to a server side session store however.
