3.1.0 (2018-03-21)
==================

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.
