PyVista 0.46.0 introduced a breaking change by requiring the use of pyvista.set_new_attribute for setting new attributes (#7716). This patch release 0.46.3 relaxes this requirement by only requiring this for setting new public attributes. Private attributes (with a _ prefix) can be set without the need to use pyvista.set_new_attribute.
