Release History
| Version | Changes | Urgency | Date |
|---|---|---|---|
| 3.13.5 | Imported from PyPI (3.13.5) | Low | 4/21/2026 |
| v3.13.5 | Bug fixes --------- - Skipped the duplicate singleton header check in lax mode (the default for response parsing). In strict mode (request parsing, or ``-X dev``), all RFC 9110 singletons are still enforced -- by :user:`bdraco`. *Related issues and pull requests on GitHub:* #12302. ---- | Medium | 3/31/2026 |
| v3.13.4 | Features -------- - Added ``max_headers`` parameter to limit the number of headers that should be read from a response -- by :user:`Dreamsorcerer`. *Related issues and pull requests on GitHub:* #11955. - Added a ``dns_cache_max_size`` parameter to ``TCPConnector`` to limit the size of the cache -- by :user:`Dreamsorcerer`. *Related issues and pull requests on GitHub:* #12106. Bug fixes --------- - Fixed server hanging indefinitely when chunked transfer encoding chunk-size d | Medium | 3/28/2026 |
| v3.13.3 | This release contains fixes for several vulnerabilities. It is advised to upgrade as soon as possible. Bug fixes --------- - Fixed proxy authorization headers not being passed when reusing a connection, which caused 407 (Proxy authentication required) errors -- by :user:`GLeurquin`. *Related issues and pull requests on GitHub:* #2596. - Fixed multipart reading failing when encountering an empty body part -- by :user:`Dreamsorcerer`. *Related issues and pull requests on GitHub:* | Low | 1/3/2026 |
| v3.13.2 | Bug fixes --------- - Fixed cookie parser to continue parsing subsequent cookies when encountering a malformed cookie that fails regex validation, such as Google's ``g_state`` cookie with unescaped quotes -- by :user:`bdraco`. *Related issues and pull requests on GitHub:* #11632. - Fixed loading netrc credentials from the default :file:`~/.netrc` (:file:`~/_netrc` on Windows) location when the :envvar:`NETRC` environment variable is not set -- by :user:`bdraco`. *Related issues and | Low | 10/28/2025 |
| v3.13.1 | Features -------- - Make configuration options in ``AppRunner`` also available in ``run_app()`` -- by :user:`Cycloctane`. *Related issues and pull requests on GitHub:* #11633. Bug fixes --------- - Switched to `backports.zstd` for Python <3.14 and fixed zstd decompression for chunked zstd streams -- by :user:`ZhaoMJ`. Note: Users who installed ``zstandard`` for support on Python <3.14 will now need to install ``backports.zstd`` instead (installing ``aiohttp[speedups]`` will do | Low | 10/17/2025 |
| v3.13.0 | Features -------- - Added support for Python 3.14. *Related issues and pull requests on GitHub:* #10851, #10872. - Added support for free-threading in Python 3.14+ -- by :user:`kumaraditya303`. *Related issues and pull requests on GitHub:* #11466, #11464. - Added support for Zstandard (aka Zstd) compression -- by :user:`KGuillaume-chaps`. *Related issues and pull requests on GitHub:* #11161. - Added ``StreamReader.total_raw_bytes`` to check the number of bytes downl | Low | 10/6/2025 |
| v3.12.15 | Bug fixes --------- - Fixed :class:`~aiohttp.DigestAuthMiddleware` to preserve the algorithm case from the server's challenge in the authorization response. This improves compatibility with servers that perform case-sensitive algorithm matching (e.g., servers expecting ``algorithm=MD5-sess`` instead of ``algorithm=MD5-SESS``) -- by :user:`bdraco`. *Related issues and pull requests on GitHub:* #11352. Improved documentation ---------------------- - Remove outdated contents of ``aioh | Low | 7/29/2025 |
| v3.12.14 | Bug fixes --------- - Fixed file uploads failing with HTTP 422 errors when encountering 307/308 redirects, and 301/302 redirects for non-POST methods, by preserving the request body when appropriate per :rfc:`9110#section-15.4.3-3.1` -- by :user:`bdraco`. *Related issues and pull requests on GitHub:* #11270. - Fixed :py:meth:`ClientSession.close() <aiohttp.ClientSession.close>` hanging indefinitely when using HTTPS requests through HTTP proxies -- by :user:`bdraco`. *Related issues | Low | 7/10/2025 |
| v3.12.13 | Bug fixes --------- - Fixed auto-created :py:class:`~aiohttp.TCPConnector` not using the session's event loop when :py:class:`~aiohttp.ClientSession` is created without an explicit connector -- by :user:`bdraco`. *Related issues and pull requests on GitHub:* #11147. ---- | Low | 6/14/2025 |
| v3.12.12 | Bug fixes --------- - Fixed cookie unquoting to properly handle octal escape sequences in cookie values (e.g., ``\012`` for newline) by vendoring the correct ``_unquote`` implementation from Python's ``http.cookies`` module -- by :user:`bdraco`. *Related issues and pull requests on GitHub:* #11173. - Fixed ``Cookie`` header parsing to treat attribute names as regular cookies per :rfc:`6265#section-5.4` -- by :user:`bdraco`. *Related issues and pull requests on GitHub:* #11178. | Low | 6/10/2025 |
| v3.12.11 | Features -------- - Improved SSL connection handling by changing the default ``ssl_shutdown_timeout`` from ``0.1`` to ``0`` seconds. SSL connections now use Python's default graceful shutdown during normal operation but are aborted immediately when the connector is closed, providing optimal behavior for both cases. Also added support for ``ssl_shutdown_timeout=0`` on all Python versions. Previously, this value was rejected on Python 3.11+ and ignored on earlier versions. Non-zero valu | Low | 6/7/2025 |
| v3.12.10 | Bug fixes --------- - Fixed leak of ``aiodns.DNSResolver`` when :py:class:`~aiohttp.TCPConnector` is closed and no resolver was passed when creating the connector -- by :user:`Tasssadar`. This was a regression introduced in version 3.12.0 (:pr:`10897`). *Related issues and pull requests on GitHub:* #11150. ---- | Low | 6/7/2025 |
| v3.12.9 | Bug fixes --------- - Fixed ``IOBasePayload`` and ``TextIOPayload`` reading entire files into memory when streaming large files -- by :user:`bdraco`. When using file-like objects with the aiohttp client, the entire file would be read into memory if the file size was provided in the ``Content-Length`` header. This could cause out-of-memory errors when uploading large files. The payload classes now correctly read data in chunks of ``READ_SIZE`` (64KB) regardless of the total content length. | Low | 6/4/2025 |
| v3.12.8 | Features -------- - Added preemptive digest authentication to :class:`~aiohttp.DigestAuthMiddleware` -- by :user:`bdraco`. The middleware now reuses authentication credentials for subsequent requests to the same protection space, improving efficiency by avoiding extra authentication round trips. This behavior matches how web browsers handle digest authentication and follows :rfc:`7616#section-3.6`. Preemptive authentication is enabled by default but can be disabled by passing ``pr | Low | 6/4/2025 |
| v3.12.7 | > [!WARNING] > This release fixes an issue where the `quote_cookie` parameter was not being properly respected for shared cookies (domain="", path=""). If your server does not handle quoted cookies correctly, you may need to disable cookie quoting by setting `quote_cookie=False` when creating your `ClientSession` or `CookieJar`. > See https://docs.aiohttp.org/en/stable/client_advanced.html#cookie-quoting-routine for details. Bug fixes --------- - Fixed cookie parsing to be more lenient | Low | 6/2/2025 |
| v3.12.7rc0 | Bug fixes --------- - Fixed cookie parsing to be more lenient when handling cookies with special characters in names or values. Cookies with characters like ``{``, ``}``, and ``/`` in names are now accepted instead of causing a :exc:`~http.cookies.CookieError` and 500 errors. Additionally, cookies with mismatched quotes in values are now parsed correctly, and quoted cookie values are now handled consistently whether or not they include special attributes like ``Domain``. Also fixed :c | Low | 6/2/2025 |
| v3.12.6 | Bug fixes --------- - Fixed spurious "Future exception was never retrieved" warnings for connection lost errors when the connector is not closed -- by :user:`bdraco`. When connections are lost, the exception is now marked as retrieved since it is always propagated through other means, preventing unnecessary warnings in logs. *Related issues and pull requests on GitHub:* #11100. ---- | Low | 5/31/2025 |
| v3.12.5 | ## This release failed to upload to PyPI because sigstore failed with 502 Server Error: Bad Gateway for url: https://rekor.sigstore.dev/api/v1/log/entries/. A new release will need to be made. Features -------- - Added ``ssl_shutdown_timeout`` parameter to :py:class:`~aiohttp.ClientSession` and :py:class:`~aiohttp.TCPConnector` to control the grace period for SSL shutdown handshake on TLS connections. This helps prevent "connection reset" errors on the server side while avoiding excessi | Low | 5/31/2025 |
| v3.12.4 | Bug fixes --------- - Fixed connector not waiting for connections to close before returning from :meth:`~aiohttp.BaseConnector.close` (partial backport of :pr:`3733`) -- by :user:`atemate` and :user:`bdraco`. *Related issues and pull requests on GitHub:* #1925, #11074. ---- | Low | 5/29/2025 |
| v3.12.3 | Bug fixes --------- - Fixed memory leak in :py:meth:`~aiohttp.CookieJar.filter_cookies` that caused unbounded memory growth when making requests to different URL paths -- by :user:`bdraco` and :user:`Cycloctane`. *Related issues and pull requests on GitHub:* #11052, #11054. ---- | Low | 5/28/2025 |
| v3.12.2 | Bug fixes --------- - Fixed ``Content-Length`` header not being set to ``0`` for non-GET requests with ``None`` body -- by :user:`bdraco`. Non-GET requests (``POST``, ``PUT``, ``PATCH``, ``DELETE``) with ``None`` as the body now correctly set the ``Content-Length`` header to ``0``, matching the behavior of requests with empty bytes (``b""``). This regression was introduced in aiohttp 3.12.1. *Related issues and pull requests on GitHub:* #11035. ---- | Low | 5/26/2025 |
| v3.12.1 | Features -------- - Added support for reusable request bodies to enable retries, redirects, and digest authentication -- by :user:`bdraco` and :user:`GLGDLY`. Most payloads can now be safely reused multiple times, fixing long-standing issues where POST requests with form data or file uploads would fail on redirects with errors like "Form data has been processed already" or "I/O operation on closed file". This also enables digest authentication to work with request bodies and allows retry mec | Low | 5/26/2025 |
| v3.12.1rc0 | Features -------- - Added support for reusable request bodies to enable retries, redirects, and digest authentication -- by :user:`bdraco` and :user:`GLGDLY`. Most payloads can now be safely reused multiple times, fixing long-standing issues where POST requests with form data or file uploads would fail on redirects with errors like "Form data has been processed already" or "I/O operation on closed file". This also enables digest authentication to work with request bodies and allows retry mec | Low | 5/26/2025 |
| v3.12.0 | Bug fixes --------- - Fixed :py:attr:`~aiohttp.web.WebSocketResponse.prepared` property to correctly reflect the prepared state, especially during timeout scenarios -- by :user:`bdraco` *Related issues and pull requests on GitHub:* #6009, #10988. - Response is now always True, instead of using MutableMapping behaviour (False when map is empty) *Related issues and pull requests on GitHub:* #10119. - Fixed connection reuse for file-like data payloads by ensuring buffer truncat | Low | 5/24/2025 |
| v3.12.0rc1 | Bug fixes --------- - Fixed :py:attr:`~aiohttp.web.WebSocketResponse.prepared` property to correctly reflect the prepared state, especially during timeout scenarios -- by :user:`bdraco` *Related issues and pull requests on GitHub:* #6009, #10988. - Response is now always True, instead of using MutableMapping behaviour (False when map is empty) *Related issues and pull requests on GitHub:* #10119. - Fixed connection reuse for file-like data payloads by ensuring buffer truncat | Low | 5/24/2025 |
