+A deprecation warning is now raised when implementations of one of the following hooks request a deprecated ``py.path.local`` parameter instead of the ``pathlib.Path`` parameter which replaced it:
+
+- :hook:`pytest_ignore_collect` - the ``path`` parameter - use ``collection_path`` instead.
+- :hook:`pytest_collect_file` - the ``path`` parameter - use ``file_path`` instead.
+- :hook:`pytest_pycollect_makemodule` - the ``path`` parameter - use ``module_path`` instead.
+- :hook:`pytest_report_header` - the ``startdir`` parameter - use ``start_path`` instead.
+- :hook:`pytest_report_collectionfinish` - the ``startdir`` parameter - use ``start_path`` instead.
+
+The replacement parameters are available since pytest 7.0.0.
+The old parameters will be removed in pytest 9.0.0.
+
+See :ref:`legacy-path-hooks-deprecated` for more details.
