-------------
Released 2020-02-26
- Extracted from Werkzeug 0.15.
- Dropped support for Python 3.4.
- ``SessionMiddleware`` sets ``secure_cookie.session`` in the environ
instead of ``werkzeug.session``.
- ``FilesystemSessionStore`` uses the filename template
``secure_cookie_%s.session`` instead of ``werkzeug_%s.sess``.
- ``SecureCookie.serialization_method`` is ``json`` instead of
``pickle``. To upgrade existing tokens, override ``unquote`` to try
``pickle`` if ``json`` fails.
