- Update from 1.26.7 to 1.26.9
- Update of rootfile
- Changelog
    1.26.9 (2022-03-16)
	* Changed ``urllib3[brotli]`` extra to favor installing Brotli libraries that are still
	  receiving updates like ``brotli`` and ``brotlicffi`` instead of ``brotlipy``.
	  This change does not impact behavior of urllib3, only which dependencies are installed.
	* Fixed a socket leaking when ``HTTPSConnection.connect()`` raises an exception.
	* Fixed ``server_hostname`` being forwarded from ``PoolManager`` to ``HTTPConnectionPool``
	  when requesting an HTTP URL. Should only be forwarded when requesting an HTTPS URL.
    1.26.8 (2022-01-07)
	* Added extra message to ``urllib3.exceptions.ProxyError`` when urllib3 detects that
	  a proxy is configured to use HTTPS but the proxy itself appears to only use HTTP.
	* Added a mention of the size of the connection pool when discarding a connection due to the pool being full.
	* Added explicit support for Python 3.11.
	* Deprecated the ``Retry.MAX_BACKOFF`` class property in favor of ``Retry.DEFAULT_MAX_BACKOFF``
	  to better match the rest of the default parameter names. ``Retry.MAX_BACKOFF`` is removed in v2.0.
	* Changed location of the vendored ``ssl.match_hostname`` function from ``urllib3.packages.ssl_match_hostname``
	  to ``urllib3.util.ssl_match_hostname`` to ensure Python 3.10+ compatibility after being repackaged
	  by downstream distributors.
	* Fixed absolute imports, all imports are now relative.
