7.10.0b1 (2020-10-29)
---------------------
Added
^^^^^
* Added ``DataFrame.groupby()`` method with all aggregations
(`#278`_, `#291`_, `#292`_, `#300`_ contributed by `@V1NAY8`_)
* Added ``es_match()`` method to ``DataFrame`` and ``Series`` for
filtering rows with full-text search (`#301`_)
* Added support for type hints of the ``elasticsearch-py`` package (`#295`_)
* Added support for passing dictionaries to ``es_type_overrides`` parameter
in the ``pandas_to_eland()`` function to directly control the field mapping
generated in Elasticsearch (`#310`_)
* Added ``es_dtypes`` property to ``DataFrame`` and ``Series`` (`#285`_)
Changed
^^^^^^^
* Changed ``pandas_to_eland()`` to use the ``parallel_bulk()``
helper instead of single-threaded ``bulk()`` helper to improve
performance (`#279`_, contributed by `@V1NAY8`_)
* Changed the ``es_type_overrides`` parameter in ``pandas_to_eland()``
to raise ``ValueError`` if an unknown column is given (`#302`_)
* Changed ``DataFrame.filter()`` to preserve the order of items
(`#283`_, contributed by `@V1NAY8`_)
* Changed when setting ``es_type_overrides={"column": "text"}`` in
``pandas_to_eland()`` will automatically add the ``column.keyword``
sub-field so that aggregations are available for the field as well (`#310`_)
Fixed
^^^^^
* Fixed ``Series.__repr__`` when the series is empty (`#306`_)

behavior as Pandas (`#270`_, contributed by `@V1NAY8`_)

Fixed
^^^^^
