Major aiohttp release.

Added support for async for and async with, e.g.

async with client.get(url) as resp:
    async for line in resp.content:
        print(line)

auto-closes response object and iterates over response's content.

Server-side signals added (allows, for example, setup http headers for long-living responses in signal hook).

Python 3.3 support dropped.

Full list of changes is pretty huge:

  • Use errors.HttpProcessingError.message as HTTP error reason and
    message #459

  • Optimize cythonized multidict a bit

  • Change repr's of multidicts and multidict views

  • default headers in ClientSession are now case-insensitive

  • Make '=' char and 'wss://' schema safe in urls #477

  • ClientResponse.close() forces connection closing by default from now #479
    N.B. Backward incompatible change: was .close(force=False) Usingforceparameter for the method is deprecated: use.release()` instead.

  • Properly requote URL's path #480

  • add skip_auto_headers parameter for client API #486

  • Properly parse URL path in aiohttp.web.Request #489

  • Skip auto-generation of Content-Type header #507

  • Use sendfile facility for static file handling #503

  • Default response_factory in app.router.add_static now is
    StreamResponse, not None. The functionality is not changed if

    .start() is still supported but responses begun with .start()
