could leak an orphan processrun_process()
could very briefly leak an orphan process.Process.aclose()

Event
andCapacityLimiter
classes to be instantiated outside an event loop threadBroadly improved/fixed the type annotations. Among other things, many functions and methods that take variadic positional arguments now make use of PEP 646
TypeVarTuple
to allow the positional arguments to be validated by static type checkers. These changes affected numerous methods and functions, including:anyio.run()
TaskGroup.start_soon()
anyio.from_thread.run()
anyio.from_thread.run_sync()
anyio.to_thread.run_sync()
anyio.to_process.run_sync()
BlockingPortal.call()
BlockingPortal.start_task_soon()
BlockingPortal.start_task()
(also resolves #560)
Fixed various type annotations of
anyio.Path
to match Typeshed:anyio.Path.__lt__()
anyio.Path.__le__()
anyio.Path.__gt__()
anyio.Path.__ge__()
anyio.Path.__truediv__()

anyio.Path.hardlink_to()
anyio.Path.samefile()
anyio.Path.symlink_to()
anyio.Path.with_segments()
(PR by Ganden Schaffner)
Fixed adjusting the total number of tokens in a

From version 1.0 our async support is now optional, as the package has minimal dependencies by default.
For async support use either
pip install 'httpcore[asyncio]'
orpip install 'httpcore[trio]'
.The project versioning policy is now explicitly governed by SEMVER. See https://semver.org/.
