[SciPy-User] ANN: pandas v0.18.0 Final released

[Jeff Reback-2]

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 or version 3.3 GH11273
• Moving and expanding window functions are now methods on Series and DataFrame similar to .groupby like objects, 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.
• The read_sas() function has been enhanced to read sas7bdat files, 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

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