Hi all, I'm happy to announce that pandas 0.20.0 and 0.20.1 have been released. Pandas 0.20.1 contains a single additional change from 0.20.0 for backwards compatibility with projects using pandas' utils methods. See https://github.com/pandas-dev/pandas/pull/16250. The full release notes for 0.20.0 are below. This is a major release from 0.19.2 and includes a number of API changes, several new features, enhancements, and performance improvements along with a large number of bug fixes. See the Whatsnew file for more information: http://pandas.pydata.org/pandas-docs/version/0.20/whatsnew.html We recommend that all users upgrade to this version. This release includes 897 commits over 5 months of development by 204 contributors. A big thank you to all contributors! Tom --- *## What is it:* pandas is a Python package providing fast, flexible, and expressive data structures designed to make working with “relational” or “labeled” data both easy and intuitive. It aims to be the fundamental high-level building block for doing practical, real world data analysis in Python. Additionally, it has the broader goal of becoming the most powerful and flexible open source data analysis / manipulation tool available in any language. *## Highlights of the 0.20.0 release include:* - new .agg() API for Series/DataFrame similar to the groupby-rolling-resample API's, see here <http://pandas.pydata.org/pandas-docs/version/0.20/whatsnew.html#whatsnew-020...> - Integration with the feather-format, including a new top-level pd.read_feather() and DataFrame.to_feather() method, see here <http://pandas.pydata.org/pandas-docs/version/0.20/io.html#io-feather> - The .ix indexer has been deprecated, see here <http://pandas.pydata.org/pandas-docs/version/0.20/whatsnew.html#whatsnew-020...> - Panel has been deprecated, see here <http://pandas.pydata.org/pandas-docs/version/0.20/whatsnew.html#whatsnew-020...> - Addition of an IntervalIndex and Interval scalar type, see here <http://pandas.pydata.org/pandas-docs/version/0.20/whatsnew.html#whatsnew-020...> - Improved user API when accessing levels in .groupby(), see here <http://pandas.pydata.org/pandas-docs/version/0.20/whatsnew.html#whatsnew-020...> - Improved support for UInt64 dtypes, see here <http://pandas.pydata.org/pandas-docs/version/0.20/whatsnew.html#whatsnew-020...> - A new orient for JSON serialization, orient='table', that uses the Table Schema spec, see here <http://pandas.pydata.org/pandas-docs/version/0.20/whatsnew.html#whatsnew-020...> - Experimental support for exporting DataFrame.style formats to Excel, see here <http://pandas.pydata.org/pandas-docs/version/0.20/whatsnew.html#whatsnew-020...> - Window Binary Corr/Cov operations now return a MultiIndexed DataFrame rather than a Panel, as Panel is now deprecated, see here <http://pandas.pydata.org/pandas-docs/version/0.20/whatsnew.html#whatsnew-020...> - Support for S3 handling now uses s3fs, see here <http://pandas.pydata.org/pandas-docs/version/0.20/whatsnew.html#whatsnew-020...> - Google BigQuery support now uses the pandas-gbq library, see here <http://pandas.pydata.org/pandas-docs/version/0.20/whatsnew.html#whatsnew-020...> - Switched the test framework to use pytest <http://docs.pytest.org/> *## How to get it:* Source tarballs and Windows / Mac / Linux wheels are available on PyPI (thanks to Christoph Gohlke for the windows wheels, and to Matthew Brett for setting up the Mac / Linux wheels) pip install --upgrade pip setuptools pip install --upgrade --upgrade-strategy=only-if-needed pandas Conda packages currently building, and will be available via the conda-forge channel (conda install pandas -c conda-forge).
