Change Logs

Version: 0.22.0-bp150.2.6
* Thu Jan 11 2018
- Format with spec-cleaner
* Wed Jan 03 2018
- 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 2017
- 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
  * Deprecations
    + pandas.tseries.register has been renamed to
    pandas.plotting.register_matplotlib_converters`() (GH18301)
  * Performance Improvements
    + Improved performance of plotting large series/dataframes
  * Conversion
    + Bug in TimedeltaIndex subtraction could incorrectly overflow
    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).

    datetime64[ns] dtype Series (GH17965)

    raising AttributeError when trying to access a missing attribute

    incorrectly coerced to float (GH18493)
  * I/O
    + Bug in not converting
    date/time columns with display formatting addressed
    (GH17990). Previously columns with display formatting were
    normally left as ordinal numbers and not converted to datetime

    where a figure generated by them is not pickleable in Python 3
