  - ## 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 9.1.3  ### Fixes  - Restart the parser on HTTP 100 - Fix chunk extensions
    quoted-string value parsing - Fix lenient_flags truncated on reset - Fix chunk extensions parameters
    parsing when more then one name-value pair provided  ## llhttp 9.1.2  ### What's Changed  - Fix HTTP 1xx
    handling  ## llhttp 9.1.1  ### What's Changed  - feat: Expose new lenient methods  ## llhttp 9.1.0  ###
    What's Changed  - New lenient flag to make CR completely optional - New lenient flag to have spaces after
    chunk header (FEDORA-2023-f2bb9ee617)
