ANN: pandas v0.19.0 released
by Joris Van den Bossche Oct. 3, 2016

Oct. 3, 2016

Hi all, I'm happy to announce pandas 0.19.0 has been released. This is a major release from 0.18.1 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 <http://pandas.pydata.org/pandas-docs/version/0.19.0/whatsnew.html> file for more information. We recommend that all users upgrade to this version. This is the work of 5 months of development by 117 contributors. A big thank you to all contributors! Joris --- *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 0.19.0 release include:* - New method merge_asof for asof-style time-series joining, see here <http://pandas.pydata.org/pandas-docs/version/0.19.0/whatsnew.html#whatsnew-…> - The .rolling() method is now time-series aware, see here <http://pandas.pydata.org/pandas-docs/version/0.19.0/whatsnew.html#whatsnew-…> - read_csv now supports parsing Categorical data, see here <http://pandas.pydata.org/pandas-docs/version/0.19.0/whatsnew.html#whatsnew-…> - A function union_categorical has been added for combining categoricals, see here <http://pandas.pydata.org/pandas-docs/version/0.19.0/whatsnew.html#whatsnew-…> - PeriodIndex now has its own period dtype, and changed to be more consistent with other Index classes. See here <http://pandas.pydata.org/pandas-docs/version/0.19.0/whatsnew.html#whatsnew-…> - Sparse data structures gained enhanced support of int and bool dtypes, see here <http://pandas.pydata.org/pandas-docs/version/0.19.0/whatsnew.html#whatsnew-…> - Comparison operations with Series no longer ignores the index, see here <http://pandas.pydata.org/pandas-docs/version/0.19.0/whatsnew.html#whatsnew-…> for an overview of the API changes. - Introduction of a pandas development API for utility functions, see here <http://pandas.pydata.org/pandas-docs/version/0.19.0/whatsnew.html#whatsnew-…> . - Deprecation of Panel4D and PanelND. We recommend to represent these types of n-dimensional data with the xarray package <http://xarray.pydata.org/en/stable/>. - Removal of the previously deprecated modules pandas.io.data, pandas.io.wb, pandas.tools.rplot. See the Whatsnew <http://pandas.pydata.org/pandas-docs/version/0.19.0/whatsnew.html> file for more information. *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). Conda packages are already available via the conda-forge channel (conda install pandas -c conda-forge). It will be available on the main channel shortly. *Issues:* Please report any issues on our issue tracker: https://github.com/pydata/pandas/issues *Thanks to all the contributors:* - adneu - Adrien Emery - agraboso - Alex Alekseyev - Alex Vig - Allen Riddell - Amol - Amol Agrawal - Andy R.
