[SciPy-User] ANN: v0.18.1 pandas Released

[Jeff Reback-2]

This is a minor bug-fix release from 0.18.0 and includes a large number of bug fixes along several new features, enhancements, and performance improvements. We recommend that all users upgrade to this version.

This was a release of 6 weeks with 210 commits by 60 authors  encompassing 142 issues and 164 pull-requests.

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:

• .groupby(...) has been enhanced to provide convenient syntax when working with .rolling(..), .expanding(..) and .resample(..) per group, see here
pd.to_datetime() has gained the ability to assemble dates from a DataFrame, see here

Method chaining improvements, see here

Custom business hour offset, see here

Many bug fixes in the handling of sparse, see here

See the Whatsnew for much more information, and the full Documentation link.

How to get it:

Source tarballs, windows wheels, and macosx wheels are available on PyPI. Windows wheels are courtesy of Christoph Gohlke, and are built on Numpy 1.10. Macosx wheels are courtesy of Matthew Brett.

Installation via conda is: conda install pandas

currently its available via the conda-forge channel: conda install pandas -c conda-forge
