Sourced from anyio's releases.

4.10.0

• Added the feed_data() method to the BufferedByteReceiveStream class, allowing users to inject data directly into the buffer
• Added various class methods to wrap existing sockets as listeners or socket streams:
  • SocketListener.from_socket()
  • SocketStream.from_socket()
  • UNIXSocketStream.from_socket()
  • UDPSocket.from_socket()
  • ConnectedUDPSocket.from_socket()
  • UNIXDatagramSocket.from_socket()
  • ConnectedUNIXDatagramSocket.from_socket()
• Added a hierarchy of connectable stream classes for transparently connecting to various remote or local endpoints for exchanging bytes or objects
• Added context manager mix-in classes (anyio.ContextManagerMixin and anyio.AsyncContextManagerMixin) to help write classes that embed other context managers, particularly cancel scopes or task groups (#905; PR by @​agronholm and @​tapetersen)
• Added the ability to specify the thread name in start_blocking_portal() (#818; PR by @​davidbrochart)
• Added anyio.notify_closing to allow waking anyio.wait_readable and anyio.wait_writable before closing a socket. Among other things, this prevents an OSError on the ProactorEventLoop. (#896; PR by @​graingert)
• Incorporated several documentation improvements from the EuroPython 2025 sprint (special thanks to the sprinters: Emmanuel Okedele, Jan Murre, Euxenia Miruna Goia and Christoffer Fjord)
• Added a documentation page explaining why one might want to use AnyIO's APIs instead of asyncio's
• Updated the to_interpreters module to use the public concurrent.interpreters API on Python 3.14 or later
• Fixed anyio.Path.copy() and anyio.Path.copy_into() failing on Python 3.14.0a7
• Fixed return annotation of __aexit__ on async context managers. CMs which can suppress exceptions should return bool, or None otherwise. (#913; PR by @​Enegg)
• Fixed rollover boundary check in SpooledTemporaryFile so that rollover only occurs when the buffer size exceeds max_size (#915; PR by @​11kkw)
• Migrated testing and documentation dependencies from extras to dependency groups
• Fixed compatibility of anyio.to_interpreter with Python 3.14.0b2 (#926; PR by @​hroncok)
• Fixed SyntaxWarning on Python 3.14 about return in finally (#816)
• Fixed RunVar name conflicts. RunVar instances with the same name should not share storage (#880; PR by @​vimfu)
• Renamed the BrokenWorkerIntepreter exception to BrokenWorkerInterpreter. The old name is available as a deprecated alias. (#938; PR by @​ayussh-verma)
• Fixed an edge case in CapacityLimiter on asyncio where a task, waiting to acquire a limiter gets cancelled and is subsequently granted a token from the limiter, but before the cancellation is delivered, and then fails to notify the next waiting task (#947)
