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 GH11273 and 3.3 GH7718
  • Moving and expanding window functions are now methods on Series and DataFrame, similar to .groupby, see here.
  • Adding support for a RangeIndex as a specialized form of the Int64Index
    for memory savings, see here.
  • API breaking .resample changes to make it more .groupby like, see here
  • Removal of support for positional indexing with floats, which was deprecated since 0.14.0. This will now raise a TypeError, see here
  • The .to_xarray() function has been added for compatibility with the xarray package see here.
  • Addition of the .str.extractall() method, and API changes to the the .str.extract() method, and the.str.cat() method
  • pd.test() top-level nose test runner is available GH4327
