Bug Fixes
~~~~~~~~~
- Fixed issue with dataframe scatter plot for categorical data that reports incorrect column key not found when categorical data is used for plotting (:issue:`16199`)
- Fixed a pytest marker failing downstream packages' tests suites (:issue:`16680`)
- Fixed compat with loading a ``DataFrame`` with a ``PeriodIndex``, from a ``format='fixed'`` HDFStore, in Python 3, that was written in Python 2 (:issue:`16781`)
- Fixed bug in ``pandas.core.window_flex_binary_moment()`` when a multi-index DataFrame is passed in as ``arg1`` (:issue:`16789`)

Conversion
^^^^^^^^^^

- Bug in pickle compat prior to the v0.20.x series, when ``UTC`` is a timezone in a Series/DataFrame/Index (:issue:`16608`)
- Bug in ``Series`` construction when passing a ``Series`` with ``dtype='category'`` (:issue:`16524`).
- Bug in ``DataFrame.astype()`` when passing a ``Series`` as the ``dtype`` kwarg. (:issue:`16717`).

Indexing
^^^^^^^^

- Bug in ``Float64Index`` causing an empty array instead of ``None`` to be returned from ``.get(np.nan)`` on a Series whose index did not contain any ``NaN`` s (:issue:`8569`)

I/O
^^^

- Bug in :func:`read_csv` in which files weren't opened as binary files by the C engine on Windows, causing EOF characters mid-field, which would fail (:issue:`16039`, :issue:`16559`, :issue:`16675`)
- Bug in :func:`read_hdf` in which reading a ``Series`` saved to an HDF file in 'fixed' format fails when an explicit ``mode='r'`` argument is supplied (:issue:`16583`)
- Bug in :func:`DataFrame.to_latex` where ``bold_rows`` was wrongly specified to be ``True`` by default, whereas in reality row labels remained non-bold whatever parameter provided. (:issue:`16707`)

Plotting
^^^^^^^^
- Fix regression in series plotting that prevented RGB and RGBA tuples from being used as color arguments (:issue:`16233`)



Groupby/Resample/Rolling
^^^^^^^^^^^^^^^^^^^^^^^^



Sparse
^^^^^^




Reshaping
^^^^^^^^^

- Bug in joining on a ``MultiIndex`` with a ``category`` dtype for a level (:issue:`16627`).
- Bug in :func:`merge` when merging/joining with multiple categorical columns (:issue:`16767`)
