`self.ssl == None` means default SSL context, not SSL disabled `#4097
`\_

View `#3880 `_
- Made cython HTTP parser set Reason-Phrase of the response to an empty string if it is
missing. `#3906 `\_

[Compare Source](https://togithub.com/aio-libs/aiohttp/compare/v3.5.1...v3.5.2)
==================
## Features
- `FileResponse` from `web_fileresponse.py` uses a `ThreadPoolExecutor` to work

- Deprecate `app.loop`, `request.loop`, `client.loop` and `connector.loop`
properties. (`#3374 `\_)
- Deprecate explicit debug argument. Use asyncio debug mode instead. (`#3381
`\_)
- Deprecate body parameter in HTTPException (and derived classes) constructor. (`#3385

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](https://togithub.com/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](https://togithub.com/aio-libs/aiohttp/issues/2206))
- Bump C HTTP parser to version 2.8 ([#2730](https://togithub.com/aio-libs/aiohttp/issues/2730))
- Accept a coroutine as an application factory in `web.run_app` and gunicorn
worker. ([#2739](https://togithub.com/aio-libs/aiohttp/issues/2739))
- Implement application cleanup context (`app.cleanup_ctx` property). ([#2747](https://togithub.com/aio-libs/aiohttp/issues/2747))
- Make `writer.write_headers` a coroutine. ([#2762](https://togithub.com/aio-libs/aiohttp/issues/2762))
- Add tracking signals for getting request/response bodies. ([#2767](https://togithub.com/aio-libs/aiohttp/issues/2767))
- Deprecate ClientResponseError.code in favor of .status to keep similarity
with response classes. ([#2781](https://togithub.com/aio-libs/aiohttp/issues/2781))
- Implement `app.add_routes()` method. ([#2787](https://togithub.com/aio-libs/aiohttp/issues/2787))
- Implement `web.static()` and `RouteTableDef.static()` API. ([#2795](https://togithub.com/aio-libs/aiohttp/issues/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](https://togithub.com/aio-libs/aiohttp/issues/2804))
- Refactor `ClientResponse` constructor: make logically required constructor
arguments mandatory, drop `_post_init()` method. ([#2820](https://togithub.com/aio-libs/aiohttp/issues/2820))
- Use `app.add_routes()` in server docs everywhere ([#2830](https://togithub.com/aio-libs/aiohttp/issues/2830))
- Websockets refactoring, all websocket writer methods are converted into
coroutines. ([#2836](https://togithub.com/aio-libs/aiohttp/issues/2836))
- Provide `Content-Range` header for `Range` requests ([#2844](https://togithub.com/aio-libs/aiohttp/issues/2844))
## Bugfixes
- Fix websocket client return EofStream. ([#2784](https://togithub.com/aio-libs/aiohttp/issues/2784))
- Fix websocket demo. ([#2789](https://togithub.com/aio-libs/aiohttp/issues/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](https://togithub.com/aio-libs/aiohttp/issues/2805))
- Close a connection if an unexpected exception occurs while sending a request
([#2827](https://togithub.com/aio-libs/aiohttp/issues/2827))
- Fix firing DNS tracing events. ([#2841](https://togithub.com/aio-libs/aiohttp/issues/2841))
## Improved Documentation
- Change `ClientResponse.json()` documentation to reflect that it now
allows "application/xxx+json" content-types ([#2206](https://togithub.com/aio-libs/aiohttp/issues/2206))
- Document behavior when cchardet detects encodings that are unknown to Python.
([#2732](https://togithub.com/aio-libs/aiohttp/issues/2732))
- Add diagrams for tracing request life style. ([#2748](https://togithub.com/aio-libs/aiohttp/issues/2748))
- Drop removed functionality for passing `StreamReader` as data at client
side. ([#2793](https://togithub.com/aio-libs/aiohttp/issues/2793))
