Hi,

I'm pleased to announce the availability of the first release candidate of
Pandas 0.15.0.
Please try this RC and report any issues here: Pandas Issues
<https://github.com/pydata/pandas/issues>
We will be releasing officially in 1-2 weeks or so.

This is a major release from 0.14.1 and includes a number of API changes,
several new features, enhancements, and performance improvements along with
a large number of bug fixes.

Highlights include:

- Drop support for numpy < 1.7.0
- The Categorical type was integrated as a first-class pandas type
- New scalar type Timedelta, and a new index type TimedeltaIndex
- New DataFrame default display for df.info() to include memory usage
- New datetimelike properties accessor .dt for Series
- Split indexing documentation into Indexing and Selecting Data and
MultiIndex / Advanced Indexing
- Split out string methods documentation into Working with Text Data
- read_csv will now by default ignore blank lines when parsing
- API change in using Indexes in set operations
- Internal refactoring of the Index class to no longer sub-class ndarray
- dropping support for PyTables less than version 3.0.0, and numexpr less
than version 2.1
