+GifImagePlugin loading strategy
+^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
+
+Pillow 9.0.0 introduced the conversion of subsequent GIF frames to ``RGB`` or ``RGBA``. This
+behaviour can now be changed so that the first ``P`` frame is converted to ``RGB`` as
+well.
+
+.. code-block:: python
+
+    from PIL import GifImagePlugin
+    GifImagePlugin.LOADING_STRATEGY = GifImagePlugin.LoadingStrategy.RGB_ALWAYS
+
+Or subsequent frames can be kept in ``P`` mode as long as there is only a single
+palette.
+
+.. code-block:: python
+
+    from PIL import GifImagePlugin
+    GifImagePlugin.LOADING_STRATEGY = GifImagePlugin.LoadingStrategy.RGB_AFTER_DIFFERENT_PALETTE_ONLY
