-- `#12069 <https://github.com/pytest-dev/pytest/issues/12069>`_: Delayed the deprecation of the following features to ``9.0.0``:
-
-  * :ref:`node-ctor-fspath-deprecation`.
-  * :ref:`legacy-path-hooks-deprecated`.

 .. note::
 
-       This release has been **yanked**: it broke some plugins without the proper warning period, due to
