+      cross-claim or counterclaim in a lawsuit) alleging that the Work
+      or a Contribution incorporated within the Work constitutes direct
+      or contributory patent infringement, then any patent licenses
+      granted to You under this License for that Work shall terminate
+      as of the date such litigation is filed.
+
+   4. Redistribution. You may reproduce and distribute copies of the
+      Work or Derivative Works thereof in any medium, with or without
+      modifications, and in Source or Object form, provided that You
+      meet the following conditions:
+
+      (a) You must give any other recipients of the Work or
+          Derivative Works a copy of this License; and
+
+      (b) You must cause any modified files to carry prominent notices
+          stating that You changed the files; and
+
+      (c) You must retain, in the Source form of any Derivative Works
+          that You distribute, all copyright, patent, trademark, and
+          attribution notices from the Source form of the Work,
+          excluding those notices that do not pertain to any part of
+          the Derivative Works; and
+
+      (d) If the Work includes a "NOTICE" text file as part of its
+          distribution, then any Derivative Works that You distribute must
+          include a readable copy of the attribution notices contained
+          within such NOTICE file, excluding those notices that do not
+          pertain to any part of the Derivative Works, in at least one
+          of the following places: within a NOTICE text file distributed
+          as part of the Derivative Works; within the Source form or
+          documentation, if provided along with the Derivative Works; or,
+          within a display generated by the Derivative Works, if and
+          wherever such third-party notices normally appear. The contents
+          of the NOTICE file are for informational purposes only and
+          do not modify the License. You may add Your own attribution
+          notices within Derivative Works that You distribute, alongside
+          or as an addendum to the NOTICE text from the Work, provided
+          that such additional attribution notices cannot be construed
+          as modifying the License.
+
+      You may add Your own copyright statement to Your modifications and
+      may provide additional or different license terms and conditions
+      for use, reproduction, or distribution of Your modifications, or
+      for any such Derivative Works as a whole, provided Your use,
+      reproduction, and distribution of the Work otherwise complies with
+      the conditions stated in this License.
+
+   5. Submission of Contributions. Unless You explicitly state otherwise,
+      any Contribution intentionally submitted for inclusion in the Work
+      by You to the Licensor shall be under the terms and conditions of
+      this License, without any additional terms or conditions.
+      Notwithstanding the above, nothing herein shall supersede or modify
+      the terms of any separate license agreement you may have executed
+      with Licensor regarding such Contributions.
+
+   6. Trademarks. This License does not grant permission to use the trade
+      names, trademarks, service marks, or product names of the Licensor,
+      except as required for reasonable and customary use in describing the
+      origin of the Work and reproducing the content of the NOTICE file.
+
+   7. Disclaimer of Warranty. Unless required by applicable law or
+      agreed to in writing, Licensor provides the Work (and each
+      Contributor provides its Contributions) on an "AS IS" BASIS,
+      WITHOUT WARRANTIES OR CONDITIONS OF ANY KIND, either express or
+      implied, including, without limitation, any warranties or conditions
+      of TITLE, NON-INFRINGEMENT, MERCHANTABILITY, or FITNESS FOR A
+      PARTICULAR PURPOSE. You are solely responsible for determining the
+      appropriateness of using or redistributing the Work and assume any
+      risks associated with Your exercise of permissions under this License.
+
+   8. Limitation of Liability. In no event and under no legal theory,
+      whether in tort (including negligence), contract, or otherwise,
+      unless required by applicable law (such as deliberate and grossly
+      negligent acts) or agreed to in writing, shall any Contributor be
+      liable to You for damages, including any direct, indirect, special,
+      incidental, or consequential damages of any character arising as a
+      result of this License or out of the use or inability to use the
+      Work (including but not limited to damages for loss of goodwill,
+      work stoppage, computer failure or malfunction, or any and all
+      other commercial damages or losses), even if such Contributor
+      has been advised of the possibility of such damages.
+
+   9. Accepting Warranty or Additional Liability. While redistributing
+      the Work or Derivative Works thereof, You may choose to offer,
+      and charge a fee for, acceptance of support, warranty, indemnity,
+      or other liability obligations and/or rights consistent with this
+      License. However, in accepting such obligations, You may act only
+      on Your own behalf and on Your sole responsibility, not on behalf
+      of any other Contributor, and only if You agree to indemnify,
+      defend, and hold each Contributor harmless for any liability
+      incurred by, or claims asserted against, such Contributor by reason
+      of your accepting any such warranty or additional liability.
+
+   END OF TERMS AND CONDITIONS

+Key Features
+============
+
+- Supports both client and server side of HTTP protocol.
+- Supports both client and server Web-Sockets out-of-the-box and avoids
+  Callback Hell.
+- Provides Web-server with middlewares and plugable routing.
+
+
+Getting started
+===============
+
+Client
+------
+
+To get something from the web:
+
+.. code-block:: python
+
+  import aiohttp
+  import asyncio
+
+  async def main():
+
+      async with aiohttp.ClientSession() as session:
+          async with session.get('http://python.org') as response:
+
+              print("Status:", response.status)
+              print("Content-type:", response.headers['content-type'])
+
+              html = await response.text()
+              print("Body:", html[:15], "...")
+
+  loop = asyncio.get_event_loop()
+  loop.run_until_complete(main())
+
+This prints:
+
+.. code-block::
+
+    Status: 200
+    Content-type: text/html; charset=utf-8
+    Body: <!doctype html> ...
+
+Coming from `requests <https://requests.readthedocs.io/>`_ ? Read `why we need so many lines <https://aiohttp.readthedocs.io/en/latest/http_request_lifecycle.html>`_.
+
+Server
+------
+
+An example using a simple server:
+
+.. code-block:: python
+
+    # examples/server_simple.py
+    from aiohttp import web
+
+    async def handle(request):
+        name = request.match_info.get('name', "Anonymous")
+        text = "Hello, " + name
+        return web.Response(text=text)
+
+    async def wshandle(request):
+        ws = web.WebSocketResponse()
+        await ws.prepare(request)
+
+        async for msg in ws:
+            if msg.type == web.WSMsgType.text:
+                await ws.send_str("Hello, {}".format(msg.data))
+            elif msg.type == web.WSMsgType.binary:
+                await ws.send_bytes(msg.data)
+            elif msg.type == web.WSMsgType.close:
+                break
+
+        return ws
+
+
+    app = web.Application()
+    app.add_routes([web.get('/', handle),
+                    web.get('/echo', wshandle),
+                    web.get('/{name}', handle)])
+
+    if __name__ == '__main__':
+        web.run_app(app)

+
+3.7.4.post0 (2021-03-06)
+========================
+
+Misc
+----
+
+- Bumped upper bound of the ``chardet`` runtime dependency
+  to allow their v4.0 version stream.
+  `#5366 <https://github.com/aio-libs/aiohttp/issues/5366>`_
+
+
+----
+
+
+3.7.4 (2021-02-25)
+==================
+
+Bugfixes
+--------
+
+- **(SECURITY BUG)** Started preventing open redirects in the
+  ``aiohttp.web.normalize_path_middleware`` middleware. For
+  more details, see
+  https://github.com/aio-libs/aiohttp/security/advisories/GHSA-v6wp-4m6f-gcjg.
+
+  Thanks to `Beast Glatisant <https://github.com/g147>`__ for
+  finding the first instance of this issue and `Jelmer Vernooij
+  <https://jelmer.uk/>`__ for reporting and tracking it down
+  in aiohttp.
+  `#5497 <https://github.com/aio-libs/aiohttp/issues/5497>`_
+- Fix interpretation difference of the pure-Python and the Cython-based
+  HTTP parsers construct a ``yarl.URL`` object for HTTP request-target.
+
+  Before this fix, the Python parser would turn the URI's absolute-path
+  for ``//some-path`` into ``/`` while the Cython code preserved it as
+  ``//some-path``. Now, both do the latter.
+  `#5498 <https://github.com/aio-libs/aiohttp/issues/5498>`_
+
+
+----
+
+
+3.7.3 (2020-11-18)
+==================
+
+Features
+--------
+
+- Use Brotli instead of brotlipy
+  `#3803 <https://github.com/aio-libs/aiohttp/issues/3803>`_
+- Made exceptions pickleable. Also changed the repr of some exceptions.
+  `#4077 <https://github.com/aio-libs/aiohttp/issues/4077>`_
+
+
+Bugfixes
+--------
+
+- Raise a ClientResponseError instead of an AssertionError for a blank
+  HTTP Reason Phrase.
+  `#3532 <https://github.com/aio-libs/aiohttp/issues/3532>`_
+- Fix ``web_middlewares.normalize_path_middleware`` behavior for patch without slash.
+  `#3669 <https://github.com/aio-libs/aiohttp/issues/3669>`_
+- Fix overshadowing of overlapped sub-applications prefixes.
+  `#3701 <https://github.com/aio-libs/aiohttp/issues/3701>`_
+- Make `BaseConnector.close()` a coroutine and wait until the client closes all connections. Drop deprecated "with Connector():" syntax.
+  `#3736 <https://github.com/aio-libs/aiohttp/issues/3736>`_
+- Reset the ``sock_read`` timeout each time data is received for a ``aiohttp.client`` response.
+  `#3808 <https://github.com/aio-libs/aiohttp/issues/3808>`_
+- Fixed type annotation for add_view method of UrlDispatcher to accept any subclass of View

+
+
+3.5.1 (2018-12-24)
+====================
+
+- Fix a regression about ``ClientSession._requote_redirect_url`` modification in debug
+  mode.
+
+3.5.0 (2018-12-22)
+====================
+
+Features
+--------
+
+- The library type annotations are checked in strict mode now.
+- Add support for setting cookies for individual request (`#2387
+  <https://github.com/aio-libs/aiohttp/pull/2387>`_)
+- Application.add_domain implementation (`#2809
+  <https://github.com/aio-libs/aiohttp/pull/2809>`_)
+- The default ``app`` in the request returned by ``test_utils.make_mocked_request`` can
+  now have objects assigned to it and retrieved using the ``[]`` operator. (`#3174
+  <https://github.com/aio-libs/aiohttp/pull/3174>`_)
+- Make ``request.url`` accessible when transport is closed. (`#3177
+  <https://github.com/aio-libs/aiohttp/pull/3177>`_)
+- Add ``zlib_executor_size`` argument to ``Response`` constructor to allow compression
+  to run in a background executor to avoid blocking the main thread and potentially
+  triggering health check failures. (`#3205
+  <https://github.com/aio-libs/aiohttp/pull/3205>`_)
+- Enable users to set ``ClientTimeout`` in ``aiohttp.request`` (`#3213
+  <https://github.com/aio-libs/aiohttp/pull/3213>`_)
+- Don't raise a warning if ``NETRC`` environment variable is not set and ``~/.netrc``
+  file doesn't exist. (`#3267 <https://github.com/aio-libs/aiohttp/pull/3267>`_)
+- Add default logging handler to web.run_app If the ``Application.debug``` flag is set
+  and the default logger ``aiohttp.access`` is used, access logs will now be output
+  using a *stderr* ``StreamHandler`` if no handlers are attached. Furthermore, if the
+  default logger has no log level set, the log level will be set to ``DEBUG``. (`#3324
+  <https://github.com/aio-libs/aiohttp/pull/3324>`_)
+- Add method argument to ``session.ws_connect()``.  Sometimes server API requires a
+  different HTTP method for WebSocket connection establishment.  For example, ``Docker
+  exec`` needs POST. (`#3378 <https://github.com/aio-libs/aiohttp/pull/3378>`_)
+- Create a task per request handling. (`#3406
+  <https://github.com/aio-libs/aiohttp/pull/3406>`_)
+
+
+Bugfixes
+--------
+
+- Enable passing ``access_log_class`` via ``handler_args`` (`#3158
+  <https://github.com/aio-libs/aiohttp/pull/3158>`_)
+- Return empty bytes with end-of-chunk marker in empty stream reader. (`#3186
+  <https://github.com/aio-libs/aiohttp/pull/3186>`_)
+- Accept ``CIMultiDictProxy`` instances for ``headers`` argument in ``web.Response``
+  constructor. (`#3207 <https://github.com/aio-libs/aiohttp/pull/3207>`_)
+- Don't uppercase HTTP method in parser (`#3233
+  <https://github.com/aio-libs/aiohttp/pull/3233>`_)
+- Make method match regexp RFC-7230 compliant (`#3235
+  <https://github.com/aio-libs/aiohttp/pull/3235>`_)
+- Add ``app.pre_frozen`` state to properly handle startup signals in
+  sub-applications. (`#3237 <https://github.com/aio-libs/aiohttp/pull/3237>`_)
+- Enhanced parsing and validation of helpers.BasicAuth.decode. (`#3239
+  <https://github.com/aio-libs/aiohttp/pull/3239>`_)
+- Change imports from collections module in preparation for 3.8. (`#3258
+  <https://github.com/aio-libs/aiohttp/pull/3258>`_)
+- Ensure Host header is added first to ClientRequest to better replicate browser (`#3265
+  <https://github.com/aio-libs/aiohttp/pull/3265>`_)
+- Fix forward compatibility with Python 3.8: importing ABCs directly from the
+  collections module will not be supported anymore. (`#3273
+  <https://github.com/aio-libs/aiohttp/pull/3273>`_)
+- Keep the query string by ``normalize_path_middleware``. (`#3278
+  <https://github.com/aio-libs/aiohttp/pull/3278>`_)
+- Fix missing parameter ``raise_for_status`` for aiohttp.request() (`#3290
+  <https://github.com/aio-libs/aiohttp/pull/3290>`_)
+- Bracket IPv6 addresses in the HOST header (`#3304
+  <https://github.com/aio-libs/aiohttp/pull/3304>`_)
+- Fix default message for server ping and pong frames. (`#3308
+  <https://github.com/aio-libs/aiohttp/pull/3308>`_)
+- Fix tests/test_connector.py typo and tests/autobahn/server.py duplicate loop
+  def. (`#3337 <https://github.com/aio-libs/aiohttp/pull/3337>`_)
+- Fix false-negative indicator end_of_HTTP_chunk in StreamReader.readchunk function
+  (`#3361 <https://github.com/aio-libs/aiohttp/pull/3361>`_)
+- Release HTTP response before raising status exception (`#3364
+  <https://github.com/aio-libs/aiohttp/pull/3364>`_)
+- Fix task cancellation when ``sendfile()`` syscall is used by static file
+  handling. (`#3383 <https://github.com/aio-libs/aiohttp/pull/3383>`_)
+- Fix stack trace for ``asyncio.TimeoutError`` which was not logged, when it is caught
+  in the handler. (`#3414 <https://github.com/aio-libs/aiohttp/pull/3414>`_)
+
+
+Improved Documentation
+----------------------
+
+- Improve documentation of ``Application.make_handler`` parameters. (`#3152
+  <https://github.com/aio-libs/aiohttp/pull/3152>`_)
+- Fix BaseRequest.raw_headers doc. (`#3215
+  <https://github.com/aio-libs/aiohttp/pull/3215>`_)
+- Fix typo in TypeError exception reason in ``web.Application._handle`` (`#3229
+  <https://github.com/aio-libs/aiohttp/pull/3229>`_)
+- Make server access log format placeholder %b documentation reflect
+  behavior and docstring. (`#3307 <https://github.com/aio-libs/aiohttp/pull/3307>`_)
+
+
+Deprecations and Removals
+-------------------------
+
+- Deprecate modification of ``session.requote_redirect_url`` (`#2278
+  <https://github.com/aio-libs/aiohttp/pull/2278>`_)
+- Deprecate ``stream.unread_data()`` (`#3260
+  <https://github.com/aio-libs/aiohttp/pull/3260>`_)
+- Deprecated use of boolean in ``resp.enable_compression()`` (`#3318
+  <https://github.com/aio-libs/aiohttp/pull/3318>`_)
+- Encourage creation of aiohttp public objects inside a coroutine (`#3331
+  <https://github.com/aio-libs/aiohttp/pull/3331>`_)
+- Drop dead ``Connection.detach()`` and ``Connection.writer``. Both methods were broken
+  for more than 2 years. (`#3358 <https://github.com/aio-libs/aiohttp/pull/3358>`_)
