This library adheres to Semantic Versioning 2.0 <http://semver.org/>_.
UNRELEASED
Added documentation on how to migrate from AnyIO 3 to 4
Fixed the type annotation of TaskGroup.start_soon() to accept any awaitables
(already in v3.7.0 but was missing from 4.0.0rc1)
Changed CancelScope to also consider the cancellation count (in addition to the cancel
message) on asyncio to determine if a cancellation exception should be swallowed on scope exit,
to combat issues where third party libraries catch the CancelledError and raise another, thus
erasing the original cancel message
4.0.0rc1
BACKWARDS INCOMPATIBLE Replaced AnyIO's own ExceptionGroup class with the PEP
654 BaseExceptionGroup and ExceptionGroup
BACKWARDS INCOMPATIBLE Changes to cancellation semantics:
Any exceptions raising out of a task groups are now nested inside an
ExceptionGroup (or BaseExceptionGroup if one or more BaseException were
included)
Fixed task group not raising a cancellation exception on asyncio at exit if no child
tasks were spawned and an outer cancellation scope had been cancelled before
Ensured that exiting a TaskGroup always hits a yield point, regardless of
whether there are running child tasks to be waited on
On asyncio, cancel scopes will defer cancelling tasks that are scheduled to resume
with a finished future
On asyncio and Python 3.9 or later, cancel scopes now only suppress cancellation
exceptions if the cancel message matches the scope
Task groups on all backends now raise a single cancellation exception when an outer
cancel scope is cancelled, and no exceptions other than cancellation exceptions are
raised in the group
BACKWARDS INCOMPATIBLE Changes the pytest plugin to run all tests and fixtures in
the same task, allowing fixtures to set context variables for tests and other fixtures
BACKWARDS INCOMPATIBLE Changed anyio.Path.relative_to() and
anyio.Path.is_relative_to() to only accept one argument, as passing multiple
arguments is deprecated as of Python 3.12
BACKWARDS INCOMPATIBLE Dropped support for spawning tasks from old-style coroutine
functions (@asyncio.coroutine)
BACKWARDS INCOMPATIBLE The policy option on the asyncio backend was
changed to loop_factory to accommodate asyncio.Runner
Changed anyio.run() to use asyncio.Runner (or a back-ported version of it on
Pythons older than 3.11) on the asyncio backend
Dropped support for Python 3.7
Added support for Python 3.12
Bumped minimum version of trio to v0.22
Added the anyio.Path.is_junction() and anyio.Path.walk() methods
