- The ``.tz_localize()`` method of ``DatetimeIndex`` and ``Timestamp`` has gained the ``errors`` keyword, so you can potentially coerce nonexistent timestamps to ``NaT``. The default behaviour remains to raising a ``NonExistentTimeError`` (:issue:`13057`)

- Correct ``KeyError`` from matplotlib when processing ``Series`` ``xerr``/``yerr`` (:issue:`13114`)
