v0.20.3 (July 7, 2017)¶
This is a minor bug-fix release in the 0.20.x series and includes some small regression fixes and bug fixes. We recommend that all users upgrade to this version.
What’s new in v0.20.3
Bug fixes¶
- Fixed a bug in failing to compute rolling computations of a column-MultiIndexed
DataFrame
(GH16789, GH16825) - Fixed a pytest marker failing downstream packages’ tests suites (GH16680)
Conversion¶
- Bug in pickle compat prior to the v0.20.x series, when
UTC
is a timezone in a Series/DataFrame/Index (GH16608) - Bug in
Series
construction when passing aSeries
withdtype='category'
(GH16524). - Bug in
DataFrame.astype()
when passing aSeries
as thedtype
kwarg. (GH16717).
Indexing¶
- Bug in
Float64Index
causing an empty array instead ofNone
to be returned from.get(np.nan)
on a Series whose index did not contain anyNaN
s (GH8569) - Bug in
MultiIndex.isin
causing an error when passing an empty iterable (GH16777) - Fixed a bug in a slicing DataFrame/Series that have a
TimedeltaIndex
(GH16637)
I/O¶
- Bug in
read_csv()
in which files weren’t opened as binary files by the C engine on Windows, causing EOF characters mid-field, which would fail (GH16039, GH16559, GH16675) - Bug in
read_hdf()
in which reading aSeries
saved to an HDF file in ‘fixed’ format fails when an explicitmode='r'
argument is supplied (GH16583) - Bug in
DataFrame.to_latex()
wherebold_rows
was wrongly specified to beTrue
by default, whereas in reality row labels remained non-bold whatever parameter provided. (GH16707) - Fixed an issue with
DataFrame.style()
where generated element ids were not unique (GH16780) - Fixed loading a
DataFrame
with aPeriodIndex
, from aformat='fixed'
HDFStore, in Python 3, that was written in Python 2 (GH16781)
Plotting¶
- Fixed regression that prevented RGB and RGBA tuples from being used as color arguments (GH16233)
- Fixed an issue with
DataFrame.plot.scatter()
that incorrectly raised aKeyError
when categorical data is used for plotting (GH16199)
