() now supports a regex argument that explicitly specifies whether the pattern is a regular expression. The error raised when an optional dependency canвЂ™t be imported now includes the original exception, for easier investigation ( GH43882)ДЄdded ExponentialMovingWindow.sum() ( GH13297) IntegerArray.all(), IntegerArray.any(), FloatingArray.any(), and FloatingArray.all() use Kleene logic ( GH41967)ДЄdded support for nullable boolean and integer types in DataFrame.to_stata(), StataWriter, StataWriter117, and StataWriterUTF8 ( GH40855)ДataFrame._pos_() and DataFrame._neg_() now retain ExtensionDtype dtypes ( GH43883)

Methods that relied on hashmap based algos such as DataFrameGroupBy.value_counts(), unt() and factorize() ignored imaginary component for complex numbers ( GH17927)ДЄdd () and () introduced in Python 3.9 to remove pre-/suffixes from string-type Series ( GH36944)ДЄttempting to write into a file in missing parent directory with DataFrame.to_csv(), DataFrame.to_html(), DataFrame.to_excel(), DataFrame.to_feather(), DataFrame.to_parquet(), DataFrame.to_stata(), DataFrame.to_json(), DataFrame.to_pickle(), and DataFrame.to_xml() now explicitly mentions missing parent directory, the same is true for Series counterparts ( GH24306) Read_table() now supports the argument storage_options ( GH39167)ДataFrame.to_stata() and StataWriter() now accept the keyword only argument value_labels to save labels for non-categorical columns ( GH38454) GroupBy.cummin() and GroupBy.cummax() now support the argument skipna ( GH34047) See Window Overview for performance and functional benefits ( GH42273) Series.ewm() and DataFrame.ewm() now support a method argument with a 'table' option that performs the windowing operation over an entire DataFrame.

A generator will be more performant, especially with replace=False ( GH38100) Series.sample(), DataFrame.sample(), and GroupBy.sample() now accept a np.random.Generator as input to random_state. to_dict ( orient = 'tight' ) Out: Other enhancements В¶Д¬oncat() will preserve the attrs when it is the same for all objects and discard the attrs when they are different ( GH41828)ДataFrameGroupBy operations with as_index=False now correctly retain ExtensionDtype dtypes for columns being grouped on ( GH41373)ДЄdd support for assigning values to by argument in () and () ( GH15079) : In : df Out: z1 x y z2 1 2 n1 n2 a b 1 3 c 2 4 In : df. caption ( GH43368)ДЄdditionally there are specific enhancements to the HTML specific rendering: Validation of certain keyword arguments, e.g. Note that formerly Styler relied on _mathjax, which has now been replaced by ( GH41395) Global options under the category pd.options.styler have been extended to configure default Styler properties which address formatting, encoding, and HTML and LaTeX rendering.

The Styler.export() and e() have been updated to address all of the added functionality from v1.2.0 and v1.3.0 ( GH40675)

The keyword arguments level and names have been added to Styler.hide() (and implicitly to the deprecated methods Styler.hide_index() and Styler.hide_columns()) for additional control of visibility of MultiIndexes and of Index names ( GH25475, GH43404, GH43346) The new method Styler.hide() deprecates Styler.hide_index() and Styler.hide_columns() ( GH43758) These mirror the signature of the methods already used to style and format data values, and work with both HTML, LaTeX and Excel format ( GH41893, GH43101, GH41993, GH41995)

Styling and formatting of indexes has been added, with Styler.apply_index(), Styler.applymap_index() and Styler.format_index(). Increased minimum versions for dependenciesДeprecated Int64Index, UInt64Index & Float64IndexДeprecated DataFrame.append and Series.append Groupby.apply consistent transform detection Unstack and pivot_table no longer raises ValueError for result that would exceed int32 limit Mangle_dupe_cols in read_csv no longer renames unique columns conflicting with target names Null-values are no longer coerced to NaN-value in value_counts and mode Ignoring dtypes in concat with empty or all-NA columns Rank function for rolling and expanding windowsДom_dict and DataFrame.to_dict have new Multi-threaded CSV reading with a new CSV Engine based on pyarrow
