   ``anyio.open_process()``, ``asyncio.create_subprocess_…()``, ``trio.run_process()``,

 - Added the ``info`` property to ``anyio.Path`` on Python 3.14
+- Changed ``anyio.getaddrinfo()`` to ignore (invalid) IPv6 name resolution results when
+  IPv6 support is disabled in Python
 - Fixed traceback formatting growing quadratically with level of ``TaskGroup``
   nesting on asyncio due to exception chaining when raising ``ExceptionGroups``
   in ``TaskGroup.__aexit__``
