+3.12.0b1 (2025-05-22)
+=====================
+
+Bug fixes
+---------
+
+- Response is now always True, instead of using MutableMapping behaviour (False when map is empty)
+
+
+  *Related issues and pull requests on GitHub:*
+  :issue:`10119`.
+
+
+
+- Fixed connection reuse for file-like data payloads by ensuring buffer
+  truncation respects content-length boundaries and preventing premature
+  connection closure race -- by :user:`bdraco`.
+
+
+  *Related issues and pull requests on GitHub:*
+  :issue:`10325`, :issue:`10915`.
+
+
+
+- Fixed pytest plugin to not use deprecated :py:mod:`asyncio` policy APIs.
+
+
+  *Related issues and pull requests on GitHub:*
+  :issue:`10851`.
+
+
+
+
+Features
+--------
+
+- Added a comprehensive HTTP Digest Authentication client middleware (DigestAuthMiddleware)
+  that implements RFC 7616. The middleware supports all standard hash algorithms
+  (MD5, SHA, SHA-256, SHA-512) with session variants, handles both 'auth' and
+  'auth-int' quality of protection options, and automatically manages the
+  authentication flow by intercepting 401 responses and retrying with proper
+  credentials -- by :user:`feus4177`, :user:`TimMenninger`, and :user:`bdraco`.
+
+
+  *Related issues and pull requests on GitHub:*
+  :issue:`2213`, :issue:`10725`.
+
+
+
+- Added client middleware support -- by :user:`bdraco` and :user:`Dreamsorcerer`.
+
+  This change allows users to add middleware to the client session and requests, enabling features like
+  authentication, logging, and request/response modification without modifying the core
+  request logic. Additionally, the ``session`` attribute was added to ``ClientRequest``,
+  allowing middleware to access the session for making additional requests.
+
+
+  *Related issues and pull requests on GitHub:*
+  :issue:`9732`, :issue:`10902`.
+
+
+
+- Allow user setting zlib compression backend -- by :user:`TimMenninger`
+
+  This change allows the user to call :func:`aiohttp.set_zlib_backend()` with the
+  zlib compression module of their choice. Default behavior continues to use
+  the builtin ``zlib`` library.
+
+
+  *Related issues and pull requests on GitHub:*
+  :issue:`9798`.
+
+
+
+- Added support for overriding the base URL with an absolute one in client sessions
+  -- by :user:`vivodi`.
+
+
+  *Related issues and pull requests on GitHub:*
+  :issue:`10074`.
+
+
+
+- Added ``host`` parameter to ``aiohttp_server`` fixture -- by :user:`christianwbrock`.
+
+
+  *Related issues and pull requests on GitHub:*
+  :issue:`10120`.
+
+
+
+- Detect blocking calls in coroutines using BlockBuster -- by :user:`cbornet`.
+
+
+  *Related issues and pull requests on GitHub:*
+  :issue:`10433`.
+
+
+
+- Added ``socket_factory`` to :py:class:`aiohttp.TCPConnector` to allow specifying custom socket options
+  -- by :user:`TimMenninger`.
+
+
+  *Related issues and pull requests on GitHub:*
+  :issue:`10474`, :issue:`10520`.
+
+
+
+- Started building armv7l manylinux wheels -- by :user:`bdraco`.
+
+
+  *Related issues and pull requests on GitHub:*
+  :issue:`10797`.
+
+
+
+- Implemented shared DNS resolver management to fix excessive resolver object creation
+  when using multiple client sessions. The new ``_DNSResolverManager`` singleton ensures
+  only one ``DNSResolver`` object is created for default configurations, significantly
+  reducing resource usage and improving performance for applications using multiple
+  client sessions simultaneously -- by :user:`bdraco`.
+
+
+  *Related issues and pull requests on GitHub:*
+  :issue:`10847`, :issue:`10923`.
+
+
+
+

+
+
+  *Related issues and pull requests on GitHub:*
+  :issue:`10662`.
+
+
+
+- Added support for building against system ``llhttp`` library -- by :user:`mgorny`.
+
+  This change adds support for :envvar:`AIOHTTP_USE_SYSTEM_DEPS` environment variable that
+  can be used to build aiohttp against the system install of the ``llhttp`` library rather
+  than the vendored one.
+
+
+  *Related issues and pull requests on GitHub:*
+  :issue:`10759`.
+
+
+
+- ``aiodns`` is now installed on Windows with speedups extra -- by :user:`bdraco`.

+
