On behalf of aiohttp development team I'm pleased to announce next aiohttp release.

It contains very long list of new features and bug fixes (see it below).

Most important changes are:

The full list of changes:

Features

  • Add SSL related params to ClientSession.request (#1128)
  • Make enable_compression work on HTTP/1.0 (#1828)
  • Deprecate registering synchronous web handlers (#1993)
  • Switch to multidict 3.0. All HTTP headers preserve casing now but compared
    in case-insensitive way. (#1994)
  • Improvement for normalize_path_middleware. Added possibility to handle URLs
    with query string. (#1995)
  • Use towncrier for CHANGES.txt build (#1997)
  • Implement trust_env=True param in ClientSession. (#1998)
  • Added variable to customize proxy headers (#2001)
  • Implement router.add_routes and router decorators. (#2004)
  • Deprecated BaseRequest.has_body in favor of
    BaseRequest.can_read_body Added BaseRequest.body_exists
    attribute that stays static for the lifetime of the request (#2005)
  • Provide BaseRequest.loop attribute (#2024)
  • Make _CoroGuard awaitable and fix ClientSession.close warning message
    (#2026)
  • Responses to redirects without Location header are returned instead of
    raising a RuntimeError (#2030)
  • Added get_client, get_server, setUpAsync and tearDownAsync methods to
    AioHTTPTestCase (#2032)
  • Add automatically a SafeChildWatcher to the test loop (#2058)
  • add ability to disable automatic response decompression (#2110)
  • Add support for throttling DNS request, avoiding the requests saturation when
    there is a miss in the DNS cache and many requests getting into the connector
    at the same time. (#2111)
  • Use request for getting access log information instead of message/transport
    pair. Add RequestBase.remote property for accessing to IP of client
    initiated HTTP request. (#2123)
  • json() raises a ContentTypeError exception if the content-type does not meet
    the requirements instead of raising a generic ClientResponseError. (#2136)
  • Make the HTTP client able to return HTTP chunks when chunked transfer
    encoding is used. (#2150)
  • add append_version arg into StaticResource.url and
    StaticResource.url_for methods for getting an url with hash (version) of
    the file. (#2157)
  • Fix parsing the Forwarded header. * commas and semicolons are allowed inside
    quoted-strings; * empty forwarded-pairs (as in for=_1;;by=_2) are allowed; *
    non-standard parameters are allowed (although this alone could be easily done
    in the previous parser). (#2173)
  • Don't require ssl module to run. aiohttp does not require SSL to function.
    The code paths involved with SSL will only be hit upon SSL usage. Raise
    RuntimeError if HTTPS protocol is required but ssl module is not present.
    (#2221)
  • Accept coroutine fixtures in pytest plugin (#2223)
  • Call shutdown_asyncgens before event loop closing on Python 3.6. (#2227)
  • Speed up Signals when there are no receivers (#2229)
  • Raise InvalidURL instead of ValueError on fetches with invalid URL.
    (#2241)
  • Move DummyCookieJar into cookiejar.py (#2242)
  • run_app: Make print=None disable printing (#2260)
  • Support brotli encoding (generic-purpose lossless compression algorithm)
    (#2270)
  • Add server support for WebSockets Per-Message Deflate. Add client option to
    add deflate compress header in WebSockets request header. If calling
    ClientSession.ws_connect() with compress=15 the client will support deflate
    compress negotiation. (#2273)
  • Support verify_ssl, fingerprint, ssl_context and proxy_headers by
    client.ws_connect. (#2292)
  • Added aiohttp.ClientConnectorSSLError when connection fails due
    ssl.SSLError (#2294)
  • aiohttp.web.Application.make_handler support access_log_class (#2315)
  • Build HTTP parser extension in non-strict mode by default. (#2332)

  • Fix missing app.loop on startup hooks during tests (#2060)

    asynchronous context manager. (#2063)

    (#2084)
  • Force use of IPv4 during test, this will make tests run in a Docker container
    (#2104)
  • Warnings about unawaited coroutines now correctly point to the user's code.
    (#2106)
  • Fix issue with IndexError being raised by the StreamReader.iter_chunks()
    generator. (#2112)
  • Support HTTP 308 Permanent redirect in client class. (#2114)
  • Fix FileResponse sending empty chunked body on 304. (#2143)
  • Do not add Content-Length: 0 to GET/HEAD/TRACE/OPTIONS requests by default.
    (#2167)
  • Fix parsing the Forwarded header according to RFC 7239. (#2170)
  • Securely determining remote/scheme/host #2171 (#2171)
  • Fix header name parsing, if name is split into multiple lines (#2183)
  • Handle session close during connection, KeyError: <aiohttp.connector._TransportPlaceholder> (#2193)
  • Fixes uncaught TypeError in helpers.guess_filename if name is not a
    string (#2201)
  • Raise OSError on async DNS lookup if resolved domain is an alias for another
    one, which does not have an A or CNAME record. (#2231)
  • Fix incorrect warning in StreamReader. (#2251)
  • Properly clone state of web request (#2284)
  • Fix C HTTP parser for cases when status line is split into different TCP
    packets. (#2311)
  • Fix web.FileResponse overriding user supplied Content-Type (#2317)

Improved Documentation

  • Add a note about possible performance degradation in await resp.text() if
    charset was not provided by Content-Type HTTP header. Pass explicit
    encoding to solve it. (#1811)
  • Drop disqus widget from documentation pages. (#2018)
  • Add a graceful shutdown section to the client usage documentation. (#2039)

    (#2198)
  • Document that all app's middleware factories are run for every request.
    (#2225)
  • Reflect the fact that default resolver is threaded one starting from aiohttp
    1.1 (#2228)

Deprecations and Removals

    environment variables are not supported anymore. (#2123)
  • Drop deprecated secure_proxy_ssl_header support (#2171)
  • Removed TimeService in favor of simple caching. TimeService also had a bug
    where it lost about 0.5 seconds per second. (#2176)
  • Drop unused response_factory from static files API (#2290)
