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:

Changes

• 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

• Raise RuntimeError when chunked enabled and HTTP is 1.0 #488

• Fix a bug with processing io.BytesIO as data parameter for client API #500

• 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
  default is not specified.

• Drop ClientResponse.message attribute, it was always implementation detail.

• Streams are optimized for speed and mostly memory in case of a big
  HTTP message sizes #496

• Fix a bug for server-side cookies for dropping cookie and setting it
  again without Max-Age parameter.

• Don't trim redirect URL in client API #499

• Extend precision of access log "D" to milliseconds #527

• Deprecate StreamResponse.start() method in favor of
  StreamResponse.prepare() coroutine #525

  .start() is still supported but responses begun with .start()
  doesn't call signal for response preparing to be sent.

• Add StreamReader.__repr__

• Drop Python 3.3 support, from now minimal required version is Python
  3.4.1 #541

• Add async with support for ClientSession.request() and family #536

• Ignore message body on 204 and 304 responses #505

• TCPConnector processed both IPv4 and IPv6 by default #559

• Add .routes() view for urldispatcher #519

• Route name should be a valid identifier name from now #567

• Implement server signals #562

• Drop an year-old deprecated files parameter from client API.

• Added async for support for aiohttp stream #542

Minor aiohttp release.

The main change is making code pep-492 compatible.
So you can use await in client API, e.g.:

async def getter(url):
    resp = await aiohttp.get(url)
    try:
        text = await resp.read()
        return text
    finally:
        await resp.release()

Changes

• Properly parse URL path in aiohttp.web.Request #489
• Add missing coroutine decorator, the code is await-compatible now

aiohttp 0.17.3 bugfix release

Changes

• Remove Content-Length header on compressed responses #450
• Support Python 3.5
• Improve performance of transport in-use list #472
• Fix connection pooling #473

Bugfix release

Changes

• Don't forget to pass data argument forward #462
• Fix multipart read bytes count #463

Bugfix release

Fixed multidict comparison (c727d25)

Major release

Actually it doesn't introduce many new features but has a lot of bug fixes.

New features are

• slightly improve client API by adding toplevel get(), post(), put(), head(), delete(), options(),
  patch() coroutines
• Add context manager support to ClientSession for session closing.
• Make StaticRoute supporting Last-Modified and If-Modified-Since headers
• Pass SSL context through proxy connector

Also please take a look on documentation: http://aiohttp.readthedocs.org/en/stable/ now has a comment section (powered by disqus) on the bottom of every page. We hope your comments will increase docs quality very well.
