Hi, This is a major release from 0.17.1 and includes a small number of API changes, several new features, enhancements, and performance improvements along with a large number of bug fixes. We recommend that all users upgrade to this version.
This was a release of 3.5 months with 381 commits by 100 authors encompassing 465 issues and 290 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*: - pandas >= 0.18.0 will no longer support compatibility with Python version 2.6 GH7718 <https://github.com/pydata/pandas/issues/7718> or version 3.3 GH11273 <https://github.com/pydata/pandas/issues/11273> - Moving and expanding window functions are now methods on Series and DataFrame similar to .groupby like objects, see here <http://pandas.pydata.org/pandas-docs/version/0.18.0/whatsnew.html#whatsnew-0180-enhancements-moments> . - Adding support for a RangeIndex as a specialized form of the Int64Index for memory savings, see here <http://pandas.pydata.org/pandas-docs/version/0.18.0/whatsnew.html#whatsnew-0180-enhancements-rangeindex> . - API breaking .resample changes to make it more .groupby like, see here <http://pandas.pydata.org/pandas-docs/version/0.18.0/whatsnew.html#whatsnew-0180-breaking-resample> - Removal of support for positional indexing with floats, which was deprecated since 0.14.0.
