- specfile:
* update copyright year
- update to version 0.22.0:
* Pandas 0.22.0 changes the handling of empty and all-NA sums and
products. The summary is that
+ The sum of an empty or all-NA Series is now 0
+ The product of an empty or all-NA Series is now 1
+ We’ve added a min_count parameter to .sum() and .prod()
controlling the minimum number of valid values for the result to
be valid. If fewer than min_count non-NA values are present, the
result is NA. The default is 0. To return NaN, the 0.21
behavior, use min_count=1.
-------------------------------------------------------------------
Sat Dec 16 23:04:54 UTC 2017 - arun@gmx.de
- update to version 0.21.1:
* Highlights include:
+ Temporarily restore matplotlib datetime plotting
functionality. This should resolve issues for users who
implicitly relied on pandas to plot datetimes with
matplotlib. See here.
+ Improvements to the Parquet IO functions introduced in
0.21.0. See here.
* Improvements to the Parquet IO functionality
+ DataFrame.to_parquet() will now write non-default indexes when
the underlying engine supports it. The indexes will be preserved
when reading back in with read_parquet() (GH18581).
+ read_parquet() now allows to specify the columns to read from a
parquet file (GH18154)
+ read_parquet() now allows to specify kwargs which are passed to
the respective engine (GH18216)
* Other Enhancements
+ Timestamp.timestamp() is now available in Python 2.7. (GH17329)
+ Grouper and TimeGrouper now have a friendly repr output
(GH18203).

+ pandas.tseries.register has been renamed to
pandas.plotting.register_matplotlib_converters`() (GH18301)
* Performance Improvements
+ Improved performance of plotting large series/dataframes
(GH18236).
* Conversion

when NaT is present (GH17791)
+ Bug in DatetimeIndex subtracting datetimelike from DatetimeIndex
could fail to overflow (GH18020)
+ Bug in IntervalIndex.copy() when copying and IntervalIndex with
non-default closed (GH18339)
+ Bug in DataFrame.to_dict() where columns of datetime that are
tz-aware were not converted to required arrays when used with
orient='records', raising"TypeError` (GH18372)
+ Bug in DateTimeIndex and date_range() where mismatching tz-aware
start and end timezones would not raise an err if end.tzinfo is
None (GH18431)
+ Bug in Series.fillna() which raised when passed a long integer
on Python 2 (GH18159).
* Indexing
+ Bug in a boolean comparison of a datetime.datetime and a
datetime64[ns] dtype Series (GH17965)

incorrectly coerced to float (GH18493)
* I/O
+ Bug in class:~pandas.io.stata.StataReader not converting
date/time columns with display formatting addressed

format in read_sql (GH17855).

numpy.bool_ datatype (GH18390)

JSON from S3 (GH17200)
+ Bug in pandas.io.json.json_normalize() to avoid modification of
meta (GH18610)
+ Bug in to_latex() where repeated multi-index values were not
printed even though a higher level index differed from the
previous row (GH14484)
+ Bug when reading NaN-only categorical columns in HDFStore
(GH18413)
+ Bug in DataFrame.to_latex() with longtable=True where a latex

+ Bug in pd.DataFrameGroupBy.count() when counting over a
datetimelike column (GH13393)
+ Bug in rolling.var where calculation is inaccurate with a

+ Bug in TimedeltaIndex subtraction could incorrectly overflow
when NaT is present (GH17791)
+ Bug in DatetimeIndex subtracting datetimelike from DatetimeIndex
could fail to overflow (GH18020)
* Categorical
+ Bug in DataFrame.astype() where casting to ‘category’ on an
empty DataFrame causes a segmentation fault (GH18004)
+ Error messages in the testing module have been improved when
items have different CategoricalDtype (GH18069)
+ CategoricalIndex can now correctly take a
pd.api.types.CategoricalDtype as its dtype (GH18116)
+ Bug in Categorical.unique() returning read-only codes array when
all categories were NaN (GH18051)
+ Bug in DataFrame.groupby(axis=1) with a CategoricalIndex
