Now the following code produces unspecified behavior:

async with session.get(url) as resp:
      pass
await resp.read()

The same for reading from resp.content.

If the response has a data into the internal buffer -- the data is returned. Otherwise, an exception is raised.
Reading from the released response is a logical error, the PR raises an exception unconditionally in the case.

The fix may break incorrect existing code but I believe that better to fail early than keeping existing inconsistent behavior.

   ### 3.3.0
   ```
   ==================

Features
--------

- Raise ``ConnectionResetError`` instead of ``CancelledError`` on trying to
  write to a closed stream. (`2499 &lt;https://github.com/aio-libs/aiohttp/pull/2499&gt;`_)
- Implement ``ClientTimeout`` class and support socket read timeout. (`2768 &lt;https://github.com/aio-libs/aiohttp/pull/2768&gt;`_)
- Enable logging when ``aiohttp.web`` is used as a program (`2956 &lt;https://github.com/aio-libs/aiohttp/pull/2956&gt;`_)
- Add canonical property to resources (`2968 &lt;https://github.com/aio-libs/aiohttp/pull/2968&gt;`_)
- Forbid reading response BODY after release (`2983 &lt;https://github.com/aio-libs/aiohttp/pull/2983&gt;`_)
- Implement base protocol class to avoid a dependency from internal
  ``asyncio.streams.FlowControlMixin`` (`2986 &lt;https://github.com/aio-libs/aiohttp/pull/2986&gt;`_)
- Cythonize ``helpers.reify``, 5% boost on macro benchmark (`2995 &lt;https://github.com/aio-libs/aiohttp/pull/2995&gt;`_)
- Optimize HTTP parser (`3015 &lt;https://github.com/aio-libs/aiohttp/pull/3015&gt;`_)
- Implement ``runner.addresses`` property. (`3036 &lt;https://github.com/aio-libs/aiohttp/pull/3036&gt;`_)
- Use ``bytearray`` instead of a list of ``bytes`` in websocket reader. It
  improves websocket message reading a little. (`3039 &lt;https://github.com/aio-libs/aiohttp/pull/3039&gt;`_)
- Remove heartbeat on closing connection on keepalive timeout. The used hack
  violates HTTP protocol. (`3041 &lt;https://github.com/aio-libs/aiohttp/pull/3041&gt;`_)
- Limit websocket message size on reading to 4 MB by default. (`3045 &lt;https://github.com/aio-libs/aiohttp/pull/3045&gt;`_)


Bugfixes
--------

- Don&#39;t reuse a connection with the same URL but different proxy/TLS settings
  (`2981 &lt;https://github.com/aio-libs/aiohttp/pull/2981&gt;`_)
- When parsing the Forwarded header, the optional port number is now preserved.
  (`3009 &lt;https://github.com/aio-libs/aiohttp/pull/3009&gt;`_)


Improved Documentation
----------------------

- Make Change Log more visible in docs (`3029 &lt;https://github.com/aio-libs/aiohttp/pull/3029&gt;`_)
- Make style and grammar improvements on the FAQ page. (`3030 &lt;https://github.com/aio-libs/aiohttp/pull/3030&gt;`_)
- Document that signal handlers should be async functions since aiohttp 3.0
  (`3032 &lt;https://github.com/aio-libs/aiohttp/pull/3032&gt;`_)


Deprecations and Removals
-------------------------

- Deprecate custom application&#39;s router. (`3021 &lt;https://github.com/aio-libs/aiohttp/pull/3021&gt;`_)
