Release 0.11.0
-----------------

:Release: 0.11.0

New Expressions
~~~~~~~~~~~~~~~

* Many new string utility expressions were added that follow the Pandas
  vectorized string methods API closely
  `<http://pandas.pydata.org/pandas-docs/stable/text.html#text-string-methods>`_.
  These are gathered under the ``.str`` sub-namespace, allowing the user to
  say::

    t.col.str.lower()

  to compute a new column with the string contents lowercased.

* Likewise, many new datetime utility expressions were added to the ``.dt``
  sub-namespace, following Pandas vectorized datetime methods API
  `<http://pandas.pydata.org/pandas-docs/stable/timeseries.html>`_.
