v0.12.0 (??????)
----------------

This is a major release from 0.11.1 and includes many new features and
enhancements along with a large number of bug fixes. There are also a 
number of important API changes that long-time pandas users should
pay close attention to.

Enhancements
~~~~~~~~~~~~

- ``pd.read_msgpack()`` and ``pd.to_msgpack()`` are now a supported method of serialization
    of arbitrary pandas (and python objects) in a lightweight portable binary format

    .. ipython:: python

          df = DataFrame(np.random.rand(5,2),columns=list('AB'))
          df.to_msgpack('foo.msg')
          pd.read_msgpack('foo.msg')

          s = Series(np.random.rand(5),index=date_range('20130101',periods=5))
          pd.to_msgpack('foo.msg', df, s)
          pd.read_msgpack('foo.msg')

    You can pass ``iterator=True`` to iterator over the unpacked results

    .. ipython:: python

          for o in pd.read_msgpack('foo.msg',iterator=True):
              print o

    .. ipython:: python
          :suppress:
          :okexcept:

          os.remove('foo.msg')
