+``Image.core.ImagingCore.id`` and ``Image.core.ImagingCore.unsafe_ptrs`` have been
+deprecated and will be removed in Pillow 12 (2025-10-15). They were used for obtaining
+raw pointers to ``ImagingCore`` internals. To interact with C code, you can use
+``Image.Image.getim()``, which returns a ``Capsule`` object.
