+``Figure.callbacks`` is deprecated
+~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
+
+The Figure ``callbacks`` property is deprecated. The only signal was
+"dpi_changed", which can be replaced by connecting to the "resize_event" on the
+canvas ``figure.canvas.mpl_connect("resize_event", func)`` instead.
+
+
+
+Passing too many positional arguments to ``tripcolor``
+~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
+... raises ``TypeError`` (extra arguments were previously ignored).
+
+
+The *filled* argument to ``Colorbar`` is removed
+~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
+This behavior was already governed by the underlying ``ScalarMappable``.
