+Autoscaling in Axes3D
+~~~~~~~~~~~~~~~~~~~~~
+
+In Matplotlib 3.2.0, autoscaling was made lazier for 2D Axes, i.e., limits
+would only be recomputed when actually rendering the canvas, or when the user
+queries the Axes limits. This performance improvement is now extended to
+`.Axes3D`. This also fixes some issues with autoscaling being triggered
+unexpectedly in Axes3D.
+
+Please see :ref:`the API change for 2D Axes <api-changes-3-2-0-autoscaling>`
+for further details.
