Sun Oct 23 01:32:23 UTC 2016 - toddrme2178@gmail.com
|

- update to version 0.19.0:
|
||
(long changelog, see http://pandas.pydata.org/pandas-docs/stable/whatsnew.html#v0-19-0-october-2-2016)
|
||
* Highlights include:
|
||
+ merge_asof() for asof-style time-series joining
|
||
+ .rolling() is now time-series aware
|
||
+ read_csv() now supports parsing Categorical data
|
||
+ A function union_categorical() has been added for combining
|
||
categoricals
|
||
+ PeriodIndex now has its own period dtype, and changed to be more
|
||
consistent with other Index classes
|
||
+ Sparse data structures gained enhanced support of int and bool
|
||
dtypes
|
||
+ Comparison operations with Series no longer ignores the index,
|
||
see here for an overview of the API changes.
|
||
+ Introduction of a pandas development API for utility functions
|
||
+ Deprecation of Panel4D and PanelND. We recommend to represent
|
||
these types of n-dimensional data with the xarray package.
|
||
+ Removal of the previously deprecated modules pandas.io.data,
|
||
pandas.io.wb, pandas.tools.rplot.
