- The ``raise_on_error`` option to plotting methods is obviated by GH3572_,
so it is removed. Plots now always raise when data cannot be plotted or the
object being plotted has a dtype of ``object``.
- ``DataFrame.interpolate()`` is now deprecated. Please use
``DataFrame.fillna()`` and ``DataFrame.replace()`` instead (GH3582_,
GH3675_, GH3676_).
