pandas 0.20.0 / 0.20.1
----------------------

**Release date:** May 5, 2017


This is a major release from 0.19.2 and includes a number of API changes, deprecations, new features,
enhancements, and performance improvements along with a large number of bug fixes. We recommend that all
users upgrade to this version.

Highlights include:

- New ``.agg()`` API for Series/DataFrame similar to the groupby-rolling-resample API's, see :ref:`here <whatsnew_0200.enhancements.agg>`
- Integration with the ``feather-format``, including a new top-level ``pd.read_feather()`` and ``DataFrame.to_feather()`` method, see :ref:`here <io.feather>`.
- The ``.ix`` indexer has been deprecated, see :ref:`here <whatsnew_0200.api_breaking.deprecate_ix>`
- ``Panel`` has been deprecated, see :ref:`here <whatsnew_0200.api_breaking.deprecate_panel>`
- Addition of an ``IntervalIndex`` and ``Interval`` scalar type, see :ref:`here <whatsnew_0200.enhancements.intervalindex>`
- Improved user API when grouping by index levels in ``.groupby()``, see :ref:`here <whatsnew_0200.enhancements.groupby_access>`
- Improved support for ``UInt64`` dtypes, see :ref:`here <whatsnew_0200.enhancements.uint64_support>`
- A new orient for JSON serialization, ``orient='table'``, that uses the Table Schema spec and that gives the possibility for a more interactive repr in the Jupyter Notebook, see :ref:`here <whatsnew_0200.enhancements.table_schema>`
- Experimental support for exporting styled DataFrames (``DataFrame.style``) to Excel, see :ref:`here <whatsnew_0200.enhancements.style_excel>`
- Window binary corr/cov operations now return a MultiIndexed ``DataFrame`` rather than a ``Panel``, as ``Panel`` is now deprecated, see :ref:`here <whatsnew_0200.api_breaking.rolling_pairwise>`
- Support for S3 handling now uses ``s3fs``, see :ref:`here <whatsnew_0200.api_breaking.s3>`
- Google BigQuery support now uses the ``pandas-gbq`` library, see :ref:`here <whatsnew_0200.api_breaking.gbq>`

See the :ref:`v0.20.1 Whatsnew <whatsnew_0200>` overview for an extensive list
of all enhancements and bugs that have been fixed in 0.20.1.


.. note::

This is a combined release for 0.20.0 and and 0.20.1.
Version 0.20.1 contains one additional change for backwards-compatibility with downstream projects using pandas' ``utils`` routines. (:issue:`16250`)

Thanks
