Sourced from anyio[trio]'s releases.

4.7.0

• Updated TaskGroup to work with asyncio's eager task factories (#764)
• Added the wait_readable() and wait_writable() functions which will accept an object with a .fileno() method or an integer handle, and deprecated their now obsolete versions (wait_socket_readable() and wait_socket_writable()) (PR by @​davidbrochart)
• Changed EventAdapter (an Event with no bound async backend) to allow set() to work even before an async backend is bound to it (#819)
• Added support for wait_readable() and wait_writable() on ProactorEventLoop (used on asyncio + Windows by default)
• Fixed a misleading ValueError in the context of DNS failures (#815; PR by @​graingert)
• Fixed the return type annotations of readinto() and readinto1() methods in the anyio.AsyncFile class (#825)
• Fixed TaskInfo.has_pending_cancellation() on asyncio returning false positives in cleanup code on Python >= 3.11 (#832; PR by @​gschaffner)
• Fixed cancelled cancel scopes on asyncio calling asyncio.Task.uncancel when propagating a CancelledError on exit to a cancelled parent scope (#790; PR by @​gschaffner)

4.6.2

• Fixed regression caused by (#807) that prevented the use of parametrized async fixtures

4.6.1

This release contains all the changes from both v4.5.1 and v4.6.0, plus:

• Fixed TaskGroup and CancelScope producing cyclic references in tracebacks when raising exceptions (#806) (PR by @​graingert)

4.6.0

• Dropped support for Python 3.8 (as #698 cannot be resolved without cancel message support)
• Fixed 100% CPU use on asyncio while waiting for an exiting task group to finish while said task group is within a cancelled cancel scope (#695)
• Fixed cancel scopes on asyncio not propagating CancelledError on exit when the enclosing cancel scope has been effectively cancelled (#698)
• Fixed asyncio task groups not yielding control to the event loop at exit if there were no child tasks to wait on
• Fixed inconsistent task uncancellation with asyncio cancel scopes belonging to a task group when said task group has child tasks running

4.5.2

• Fixed regression caused by (#807) that prevented the use of parametrized async fixtures.

4.5.1

As Python 3.8 support was dropped in v4.6.0, this interim release was created to bring a regression fix to Python 3.8, and adds a few other fixes also present in v4.6.1.

• Fixed acquring a lock twice in the same task on asyncio hanging instead of raising a RuntimeError (#798)
• Fixed an async fixture's self being different than the test's self in class-based tests (#633) (PR by @​agronholm and @​graingert)
• Fixed TypeError with TLSStream on Windows when a certificate verification error occurs when using a truststore SSL certificate (#795)
• Corrected documentation on anyio.Path regarding the limitations imposed by the current Python version on several of its methods, and made the is_junction method unavailable on Python versions earlier than 3.12 (#794)

4.5.0

• Improved the performance of anyio.Lock and anyio.Semaphore on asyncio (even up to 50 %)
• Added the fast_acquire parameter to anyio.Lock and anyio.Semaphore to further boost performance at the expense of safety (acquire() will not yield control back if there is no contention)
• Added support for the from_uri(), full_match(), parser methods/properties in anyio.Path, newly added in Python 3.13 (#737)
• Added support for more keyword arguments for run_process() and open_process(): startupinfo, creationflags, pass_fds, user, group, extra_groups and umask (#742)
• Improved the type annotations and support for PathLike in run_process() and open_process() to allow for path-like arguments, just like subprocess.Popen
• Changed the ResourceWarning from an unclosed memory object stream to include its address for easier identification
• Changed start_blocking_portal() to always use daemonic threads, to accommodate the "loitering event loop" use case
• Bumped the minimum version of Trio to v0.26.1
• Fixed __repr__() of MemoryObjectItemReceiver, when item is not defined (#767; PR by @​Danipulok)
• Fixed to_process.run_sync() failing to initialize if __main__.__file__ pointed to a file in a nonexistent directory (#696)
• Fixed AssertionError: feed_data after feed_eof on asyncio when a subprocess is closed early, before its output has been read (#490)
• Fixed TaskInfo.has_pending_cancellation() on asyncio not respecting shielded scopes (#771; PR by @​gschaffner)
• Fixed SocketStream.receive() returning bytearray instead of bytes when using asyncio with ProactorEventLoop (Windows) (#776)
