+Removal of deprecated ``offsetbox`` APIs
+~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
+The following APIs were removed:
+
+- the *s* kwarg to `.AnnotationBbox.get_fontsize` (which had no effect),
+- the ``DraggableBase.artist_picker`` method (set the artist's picker instead),
+- the ``DraggableBase.on_motion_blit`` method (use `.DraggableBase.on_motion`
+  instead).
