anyio 4.3.0

on Python PyPI

Added support for the Python 3.12 walk_up keyword argument in anyio.Path.relative_to() (PR by Colin Taylor)

Fixed passing total_tokens to anyio.CapacityLimiter() as a keyword argument not working on the trio backend (#515)

Fixed Process.aclose() not performing the minimum level of necessary cleanup when cancelled. Previously:

• Cancellation of Process.aclose() could leak an orphan process
• Cancellation of run_process() could very briefly leak an orphan process.
• Cancellation of Process.aclose() or run_process() on Trio could leave standard streams unclosed

(PR by Ganden Schaffner)

Fixed Process.stdin.aclose(), Process.stdout.aclose(), and Process.stderr.aclose() not including a checkpoint on asyncio (PR by Ganden Schaffner)

Fixed documentation on how to provide your own typed attributes
