[SciPy-User] ANN: pandas v0.19.0 released

Joris Van den Bossche
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 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!



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
  • The .rolling() method is now time-series aware, see here
  • read_csv now supports parsing Categorical data, see here
  • A function union_categorical has been added for combining categoricals, see here
  • PeriodIndex now has its own period dtype, and changed to be more consistent with other Index classes. See here
  • Sparse data structures gained enhanced support of int and bool dtypes, see here
  • Comparison operations with Series no longer ignores the index, see here for an overview of the API changes.
  • Introduction of a pandas development API for utility functions, see here.
  • Deprecation of Panel4D and PanelND. We recommend to represent these types of n-dimensional data with the xarray package.
  • Removal of the previously deprecated modules pandas.io.data, pandas.io.wb, pandas.tools.rplot.

See the Whatsnew 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.
