Hi, I'm pleased to announce the availability of the second release candidate of Pandas 0.18.0. Please try this RC and report any issues here: Pandas Issues <https://github.com/pydata/pandas/issues>. Compared to RC1, we have added updated read_sas and fixed float indexing. We will be releasing officially very shortly.
THIS IS NOT A PRODUCTION RELEASE 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. Highlights include: - 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-docs.github.io/pandas-docs-travis/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-docs.github.io/pandas-docs-travis/whatsnew.html#whatsnew-0180-enhancements-rangeindex> . - API breaking .resample changes to make it more .groupby like, see here <http://pandas-docs.github.io/pandas-docs-travis/whatsnew.html#whatsnew-0180-breaking-resample> - Removal of support for positional indexing with floats, which was deprecated since 0.14.0. This will now raise a TypeError, see here <http://pandas-docs.github.io/pandas-docs-travis/whatsnew.html#whatsnew-0180-float-indexers> - The .to_xarray() function has been added for compatibility with the xarray package <http://xarray.pydata.org/en/stable/> see here <http://pandas-docs.github.io/pandas-docs-travis/whatsnew.html#whatsnew-0180-enhancements-xarray> . - The read_sas() function has been enhanced to read sas7bdat files, see here <http://pandas-docs.github.io/pandas-docs-travis/whatsnew.html#whatsnew-0180-enhancements-sas> - Addition of the .str.extractall() method <http://pandas-docs.github.io/pandas-docs-travis/whatsnew.html#whatsnew-0180-enhancements-extractall>, and API changes to the the .str.extract() method <http://pandas-docs.github.io/pandas-docs-travis/whatsnew.html#whatsnew-0180-enhancements-extract>, and the .str.cat() method <http://pandas-docs.github.io/pandas-docs-travis/whatsnew.html#whatsnew-0180-enhancements-strcat> - pd.test() top-level nose test runner is available GH4327 <https://github.com/pydata/pandas/issues/4327> See the Whatsnew <http://pandas-docs.github.io/pandas-docs-travis/whatsnew.html> for much more information. Best way to get this is to install via conda <http://pandas-docs.github.io/pandas-docs-travis/install.html#installing-pandas-with-anaconda> from our development channel.
