    Security fix for CVE-2023-47627

    ## python-aiohttp 3.8.6 (2023-10-07)

    https://github.com/aio-libs/aiohttp/blob/v3.8.6/CHANGES.rst#386-2023-10-07

    ### Security bugfixes

    - Upgraded `llhttp` to v9.1.3: https://github.com/aio-libs/aiohttp/security/advisories/GHSA-pjjw-qhg8-p2p9
    - Updated Python parser to comply with RFCs 9110/9112: https://github.com/aio-
    libs/aiohttp/security/advisories/GHSA-gfw2-4jvh-wgfg

    ### Deprecation

    - Added `fallback_charset_resolver` parameter in `ClientSession` to allow a user-supplied character set
    detection function. Character set detection will no longer be included in 3.9 as a default. If this
    feature is needed, please use
    [`fallback_charset_resolver`](https://docs.aiohttp.org/en/stable/client_advanced.html#character-set-
    detection).

    ### Features

    - Enabled lenient response parsing for more flexible parsing in the client (this should resolve some
    regressions when dealing with badly formatted HTTP responses).

    ### Bugfixes

    - Fixed `PermissionError` when `.netrc` is unreadable due to permissions.
    - Fixed output of parsing errors pointing to a `\n`.
    - Fixed `GunicornWebWorker` max_requests_jitter not working.
    - Fixed sorting in `filter_cookies` to use cookie with longest path.
    - Fixed display of `BadStatusLine` messages from `llhttp`.

    ----

    ## llhttp 9.1.1

    ### What's Changed

    - feat: Expose new lenient methods

    ## llhttp 9.1.0
