Sourced fromanyio's releases.

4.7.0

• UpdatedTaskGroup to work with asyncio's eager task factories (#764)
• Added thewait_readable() andwait_writable() functions which will accept an object with a.fileno() method or an integer handle, and deprecated their now obsolete versions (wait_socket_readable() andwait_socket_writable()) (PR by@​davidbrochart)
• ChangedEventAdapter (anEvent with no bound async backend) to allowset() to work even before an async backend is bound to it (#819)
• Added support forwait_readable() andwait_writable() onProactorEventLoop (used on asyncio + Windows by default)
• Fixed a misleadingValueError in the context of DNS failures (#815; PR by@​graingert)
• Fixed the return type annotations ofreadinto() andreadinto1() methods in theanyio.AsyncFile class (#825)
• FixedTaskInfo.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 callingasyncio.Task.uncancel when propagating aCancelledError 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 propagatingCancelledError 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 aRuntimeError (#798)
• Fixed an async fixture'sself being different than the test'sself in class-based tests (#633) (PR by@​agronholm and@​graingert)
• FixedTypeError withTLSStream on Windows when a certificate verification error occurs when using atruststore SSL certificate (#795)
• Corrected documentation onanyio.Path regarding the limitations imposed by the current Python version on several of its methods, and made theis_junction method unavailable on Python versions earlier than 3.12 (#794)

4.5.0

• Improved the performance ofanyio.Lock andanyio.Semaphore on asyncio (even up to 50 %)
• Added thefast_acquire parameter toanyio.Lock andanyio.Semaphore to further boost performance at the expense of safety (acquire() will not yield control back if there is no contention)
• Added support for thefrom_uri(),full_match(),parser methods/properties inanyio.Path, newly added in Python 3.13 (#737)
• Added support for more keyword arguments forrun_process() andopen_process():startupinfo,creationflags,pass_fds,user,group,extra_groups andumask (#742)
• Improved the type annotations and support forPathLike inrun_process() andopen_process() to allow for path-like arguments, just likesubprocess.Popen
• Changed theResourceWarning from an unclosed memory object stream to include its address for easier identification
• Changedstart_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__() ofMemoryObjectItemReceiver, whenitem is not defined (#767; PR by@​Danipulok)
• Fixedto_process.run_sync() failing to initialize if__main__.__file__ pointed to a file in a nonexistent directory (#696)
• FixedAssertionError: feed_data after feed_eof on asyncio when a subprocess is closed early, before its output has been read (#490)
• FixedTaskInfo.has_pending_cancellation() on asyncio not respecting shielded scopes (#771; PR by@​gschaffner)
• FixedSocketStream.receive() returningbytearray instead ofbytes when using asyncio withProactorEventLoop (Windows) (#776)
