Version history

This library adheres to Semantic Versioning 2.0 <http://semver.org/>_.

3.4.0

• Added context propagation to/from worker threads in to_thread.run_sync(), from_thread.run() and from_thread.run_sync() ([#363](https://github.com/agronholm/anyio/issues/363) <https://github.com/agronholm/anyio/issues/363>_; partially based on a PR by Sebastián Ramírez)

  NOTE: Requires Python 3.7 to work properly on asyncio!

• Fixed race condition in Lock and Semaphore classes when a task waiting on acquire() is cancelled while another task is waiting to acquire the same primitive ([#387](https://github.com/agronholm/anyio/issues/387) <https://github.com/agronholm/anyio/issues/387>_)

• Fixed async context manager's __aexit__() method not being called in BlockingPortal.wrap_async_context_manager() if the host task is cancelled ([#381](https://github.com/agronholm/anyio/issues/381) <https://github.com/agronholm/anyio/issues/381>_; PR by Jonathan Slenders)

• Fixed worker threads being marked as being event loop threads in sniffio

• Fixed task parent ID not getting set to the correct value on asyncio

• Enabled the test suite to run without IPv6 support, trio or pytest plugin autoloading

3.3.4

• Fixed BrokenResourceError instead of EndOfStream being raised in TLSStream when the peer abruptly closes the connection while TLSStream is receiving data with standard_compatible=False set

3.3.3

• Fixed UNIX socket listener not setting accepted sockets to non-blocking mode on asyncio
• Changed unconnected UDP sockets to be always bound to a local port (on "any" interface) to avoid errors on asyncio + Windows

3.3.2

• Fixed cancellation problem on asyncio where level-triggered cancellation for all parent cancel scopes would not resume after exiting a shielded nested scope ([#370](https://github.com/agronholm/anyio/issues/370) <https://github.com/agronholm/anyio/issues/370>_)

3.3.1

• Added missing documentation for the ExceptionGroup.exceptions attribute
• Changed the asyncio test runner not to use uvloop by default (to match the behavior of anyio.run())
• Fixed RuntimeError on asyncio when a CancelledError is raised from a task spawned through a BlockingPortal ([#357](https://github.com/agronholm/anyio/issues/357) <https://github.com/agronholm/anyio/issues/357>_)
• Fixed asyncio warning about a Future with an exception that was never retrieved which happened when a socket was already written to but the peer abruptly closed the connection
