- update to 2.0.2:
* Handle multiple tokens in ``Connection`` header when routing
WebSocket requests.
* Set the debugger pin cookie secure flag when on https.
* Fix type annotation for ``MultiDict.update`` to accept iterable
values :pr:`2142`
* Prevent double encoding of redirect URL when ``merge_slash=True``
for ``Rule.match``.
* ``CombinedMultiDict.to_dict`` with ``flat=False`` considers all
component dicts when building value lists. :issue:`2189`
* ``send_file`` only sets a detected ``Content-Encoding`` if
``as_attachment`` is disabled to avoid browsers saving
decompressed ``.tar.gz`` files.

``Optional`` value if both ``default`` and ``type`` are not
``None``.
* Fix type annotation for routing rule factories to accept
``Iterable[RuleFactory]`` instead of ``Iterable[Rule]`` for the
``rules`` parameter. :issue:`2183`
* Add missing type annotation for ``FileStorage.__getattr__``
* The debugger pin cookie is set with ``SameSite`` set to ``Strict``
instead of ``None`` to be compatible with modern browser security.

``BinaryIO`` and ``TextIO`` for wider type compatibility.

* Fix memory usage for locals when using Python 3.6 or pre 0.4.17
greenlet versions. :pr:`2212`
