 asyncio
 -------

 *:mod:`asyncio` now uses double linked list implementation for native tasks
  which speeds up execution by 10% on standard pyperformance benchmarks and
  reduces memory usage.
 *:mod:`asyncio` has a new per-thread double linked list implementation internally for
 :class:`native tasks <asyncio.Task>` which speeds up execution by 10-20% on standard
  pyperformance benchmarks and reduces memory usage.
  This enables external introspection tools such as
 :ref:`python -m asyncio pstree<whatsnew314-asyncio-introspection>`
  to introspect the call graph of asyncio tasks running in all threads.
  (Contributed by Kumar Aditya in:gh:`107803`.)

 *:mod:`asyncio` has first class support for:term:`free-threading builds <free threading>`.
  This enables parallel execution of multiple event loops across different threads and scales
  linearly with the number of threads.
  (Contributed by Kumar Aditya in:gh:`128002`.)

 *:mod:`asyncio` has new utility functions for introspecting and printing
  the program's call graph::func:`asyncio.capture_call_graph` and
 :func:`asyncio.print_call_graph`.
    *:class:`asyncio.WindowsProactorEventLoopPolicy`
    *:func:`asyncio.get_event_loop_policy`
    *:func:`asyncio.set_event_loop_policy`
    *:func:`asyncio.set_event_loop`

    Users should use:func:`asyncio.run` or:class:`asyncio.Runner` with
    *loop_factory* to use the desired event loop implementation.
