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>`_.
