Show key headers only | View raw

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-0190-enhancements-asof-merge>
   - The .rolling() method is now time-series aware, see here
   <http://pandas.pydata.org/pandas-docs/version/0.19.0/whatsnew.html#whatsnew-0190-enhancements-rolling-ts>
   - read_csv now supports parsing Categorical data, see here
   <http://pandas.pydata.org/pandas-docs/version/0.19.0/whatsnew.html#whatsnew-0190-enhancements-read-csv-categorical>
   - 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-0190-enhancements-union-categoricals>
   - 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-0190-api-period>
   - 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-0190-sparse>
   - Comparison operations with Series no longer ignores the index, see here
   <http://pandas.pydata.org/pandas-docs/version/0.19.0/whatsnew.html#whatsnew-0190-api-series-ops>
   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-0190-dev-api>
   .
   - 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.
