I'm pleased to announce a major release of xray, v0.4.

xray is an open source project and Python package that aims to bring the
labeled data power of pandas to the physical sciences, by providing
N-dimensional variants of the core pandas data structures.

Our goal is to provide a pandas-like and pandas-compatible toolkit for
analytics on multi-dimensional arrays, rather than the tabular data for
which pandas excels. Our approach adopts the Common Data Model for
self-describing scientific data in widespread use in the Earth sciences:
xray.Dataset is an in-memory representation of a netCDF file.

Documentation: http://xray.readthedocs.org/
GitHub: https://github.com/xray/xray

Highlights of this release:

* Automatic alignment of index labels in arithmetic and when combining
arrays or datasets.
* Aggregations like mean now skip missing values by default.
* Relaxed equality rules in concat and merge for variables with equal
value(s) but different shapes.
* New drop method for dropping variables or index labels.
* Support for reindexing with a fill method like pandas.

Best,
Stephan
