Welcome to aiohttp 3.1 release.

This is an incremental release, fully backward compatible with aiohttp 3.0.

But we have added several new features.

The most visible one is app.add_routes() (an alias for existing
app.router.add_routes(). The addition is very important because
all aiohttp docs now uses app.add_routes() call in code
snippets. All your existing code still do register routes / resource
without any warning but you've got the idea for a favorite way: noisy
app.router.add_get() is replaced by app.add_routes().

The library does not make a preference between decorators::

routes = web.RouteTableDef()

@routes.get('/')
async def hello(request):
return web.Response(text="Hello, world")

app.add_routes(routes)

and route tables as a list::

async def hello(request):
return web.Response(text="Hello, world")

app.add_routes([web.get('/', hello)])

Both ways are equal, user may decide basing on own code taste.

Also we have a lot of minor features, bug fixes and documentation
updates, see below.

Features

  • Relax JSON content-type checking in the ClientResponse.json() to allow
    "application/xxx+json" instead of strict "application/json". (#2206)
  • Bump C HTTP parser to version 2.8 (#2730)
  • Accept a coroutine as an application factory in web.run_app and gunicorn
    worker. (#2739)
  • Implement application cleanup context (app.cleanup_ctx property). (#2747)
  • Make writer.write_headers a coroutine. (#2762)
  • Add tracking signals for getting request/response bodies. (#2767)
  • Deprecate ClientResponseError.code in favor of .status to keep similarity
    with response classes. (#2781)
  • Implement app.add_routes() method. (#2787)
  • Implement web.static() and RouteTableDef.static() API. (#2795)
  • Install a test event loop as default by asyncio.set_event_loop(). The
    change affects aiohttp test utils but backward compatibility is not broken
    for 99.99% of use cases. (#2804)
  • Refactor ClientResponse constructor: make logically required constructor
    arguments mandatory, drop _post_init() method. (#2820)
  • Use app.add_routes() in server docs everywhere (#2830)
  • Websockets refactoring, all websocket writer methods are converted into
    coroutines. (#2836)
  • Provide Content-Range header for Range requests (#2844)

Bugfixes

  • Fix websocket client return EofStream. (#2784)
  • Fix websocket demo. (#2789)
  • Property BaseRequest.http_range now returns a python-like slice when
    requesting the tail of the range. It's now indicated by a negative value in
    range.start rather then in range.stop (#2805)
  • Close a connection if an unexpected exception occurs while sending a request
    (#2827)
  • Fix firing DNS tracing events. (#2841)

Improved Documentation

  • Change ClientResponse.json() documentation to reflect that it now
    allows "application/xxx+json" content-types (#2206)
  • Document behavior when cchardet detects encodings that are unknown to Python.
    (#2732)
  • Add diagrams for tracing request life style. (#2748)
  • Drop removed functionality for passing StreamReader as data at client
    side. (#2793)
