One major caveat is that arrays created with numpy 2.0’s new StringDtype will convert to object dtyped arrays upon Series/DataFrame creation. Full support for numpy 2.0’s StringDtype is expected to land in pandas 3.0. * As usual please report any bugs discovered to our issue tracker ## Fixed regressions * DataFrame.__dataframe__() was producing incorrect data buffers when the a column’s type was a pandas nullable on with missing values (GH 56702) * DataFrame.__dataframe__() was producing incorrect data buffers when the a column’s type was a pyarrow nullable on with missing values (GH 57664) * Avoid issuing a spurious DeprecationWarning when a custom DataFrame or Series subclass method is called (GH 57553) * Fixed regression in precision of to_datetime() with string and unit input (GH 57051) ## Bug fixes * DataFrame.__dataframe__() was producing incorrect data buffers when the column’s type was nullable boolean (GH 55332) * DataFrame.__dataframe__() was showing bytemask instead of bitmask for 'string[pyarrow]' validity buffer (GH 57762) * DataFrame.__dataframe__() was showing non-null validity buffer (instead of None) 'string[pyarrow]' without missing values (GH 57761) * DataFrame.to_sql() was failing to find the right table when using the schema argument (GH 57539) - Remove obsolete python39 multibuild - Add pandas-pr58269-pyarrow16xpass.patch gh#pandas-dev/pandas#58269 ------------------------------------------------------------------- Mon Mar 4 20:44:10 UTC 2024 - Ben Greiner <code@bnavigator.de> - No xarrary for python 3.9 anymore: Remove from pandas[all] and exclude pandas[computation]. Reenable testing to check it. It will be skipped automatically when python39 is dropped from Tumbleweed globally. - Fix 15.x build: requires newer compiler - Fix 15.x test skips: sle15_python_module_pythons needs to be declared earlier ------------------------------------------------------------------- Fri Feb 23 20:04:59 UTC 2024 -

This decision was made because the warning was too noisy for too many users and a lot of feedback was collected about the decision to make PyArrow a required dependency. Pandas is currently considering the decision whether or not PyArrow should be added as a hard dependency in 3.0. Interested users can follow the discussion here. * Added the argument skipna to `DataFrameGroupBy.first`, `DataFrameGroupBy.last`, `SeriesGroupBy.first`, and `SeriesGroupBy.last`; achieving skipna=False used to be available via `DataFrameGroupBy.nth`, but the behavior was changed in pandas 2.0.0 (#57019) * Added the argument skipna to `Resampler.first`, `Resampler.last` (#57019) -

The xlrd package is now only for reading old-style .xls files. Previously, the default argument engine=None to read_excel() would result in using the xlrd engine in many cases, including new Excel 2007+ (.xlsx) files. If openpyxl is installed, many of these cases will now default to using the openpyxl engine. See the read_excel() documentation for more details. Thus, it is strongly encouraged to install openpyxl to read Excel 2007+ (.xlsx) files. Please do not report issues when using ``xlrd`` to read ``.xlsx`` files. This is no longer supported, switch to using openpyxl instead. Attempting to use the xlwt engine will raise a FutureWarning unless the option io.excel.xls.writer is set to "xlwt". While this option is now deprecated and will also raise a FutureWarning, it can be globally set and the warning suppressed. Users are recommended to write .xlsx files using the openpyxl engine instead. Enhancements * Optionally disallow duplicate labels * Passing arguments to fsspec backends * Support for binary file handles in to_csv * Support for short caption and table position in to_latex * Change in default floating precision for read_csv and read_table * Experimental nullable data types for float data * Index/column name preservation when aggregating * GroupBy supports EWM operations directly Deprecations * https://pandas.pydata.org/docs/whatsnew/v1.2.0.html#deprecations - Skip python36 build: New minimum supported Python is 3.7.1 - Only Suggest instead of Recommend optional dependencies.

For N-D labeled data structures, please use xarray * read_pickle read_msgpack are only guaranteed backwards compatible back to pandas version 0.20.3 + Enhancements * Groupby aggregation with relabeling Pandas has added special groupby behavior, known as "named aggregation", for naming the output columns when applying multiple aggregation functions to specific columns. * Groupby Aggregation with multiple lambdas You can now provide multiple lambda functions to a list-like aggregation in pandas.core.groupby.GroupBy.agg. * Better repr for MultiIndex Printing of MultiIndex instances now shows tuples of each row and ensures that the tuple items are vertically aligned, so it's now easier to understand the structure of the MultiIndex. * Shorter truncated repr for Series and DataFrame Currently, the default display options of pandas ensure that when a Series or DataFrame has more than 60 rows, its repr gets truncated to this maximum of 60 rows (the display.max_rows option). However, this still gives a repr that takes up a large part of the vertical screen estate. Therefore, a new option display.min_rows is introduced with a default of 10 which determines the number of rows showed in the truncated repr: * Json normalize with max_level param support json_normalize normalizes the provided input dict to all nested levels. The new max_level parameter provides more control over which level to end normalization. * Series.explode to split list-like values to rows Series and DataFrame have gained the DataFrame.explode methods to transform list-likes to individual rows. * DataFrame.plot keywords logy, logx and loglog can now accept the value 'sym' for symlog scaling. * Added support for ISO week year format ('%G-%V-%u') when parsing datetimes using to_datetime * Indexing of DataFrame and Series now accepts zerodim np.ndarray * Timestamp.replace now supports the fold argument to disambiguate DST transition times * DataFrame.at_time and Series.at_time now support datetime.time objects with timezones * DataFrame.pivot_table now accepts an observed parameter which is passed to underlying calls to DataFrame.groupby to speed up grouping categorical data. * Series.str has gained Series.str.casefold method to removes all case distinctions present in a string * DataFrame.set_index now works for instances of abc.Iterator, provided their output is of the same length as the calling frame * DatetimeIndex.union now supports the sort argument. The behavior of the sort parameter matches that of Index.union * RangeIndex.union now supports the sort argument. If sort=False an unsorted Int64Index is always returned. sort=None is the default and returns a monotonically increasing RangeIndex if possible or a sorted Int64Index if not * TimedeltaIndex.intersection now also supports the sort keyword * DataFrame.rename now supports the errors argument to raise errors when attempting to rename nonexistent keys * Added api.frame.sparse for working with a DataFrame whose values are sparse * RangeIndex has gained ~RangeIndex.start, ~RangeIndex.stop, and ~RangeIndex.step attributes * datetime.timezone objects are now supported as arguments to timezone methods and constructors * DataFrame.query and DataFrame.eval now supports quoting column names with backticks to refer to names with spaces * merge_asof now gives a more clear error message when merge keys are categoricals that are not equal * pandas.core.window.Rolling supports exponential (or Poisson) window type * Error message for missing required imports now includes the original import error's text * DatetimeIndex and TimedeltaIndex now have a mean method * DataFrame.describe now formats integer percentiles without decimal point * Added support for reading SPSS .sav files using read_spss * Added new option plotting.backend to be able to select a plotting backend different than the existing matplotlib one. Use pandas.set_option('plotting.backend', '<backend-module>') where <backend-module is a library implementing the pandas plotting API * pandas.offsets.BusinessHour supports multiple opening hours intervals * read_excel can now use openpyxl to read Excel files via the engine='openpyxl' argument. This will become the default in a future release * pandas.io.excel.read_excel supports reading OpenDocument tables. Specify engine='odf' to enable. Consult the IO User Guide <io.ods> for more details * Interval, IntervalIndex, and ~arrays.IntervalArray have gained an ~Interval.is_empty attribute denoting if the given interval(s) are empty + Backwards incompatible API changes * Indexing with date strings with UTC offsets Indexing a DataFrame or Series with a DatetimeIndex with a date string with a UTC offset would previously ignore the UTC offset. Now, the UTC offset is respected in indexing. * MultiIndex constructed from levels and codes Constructing a MultiIndex with NaN levels or codes value < -1 was allowed previously. Now, construction with codes value < -1 is not allowed and NaN levels' corresponding codes would be reassigned as -1. * Groupby.apply on DataFrame evaluates first group only once The implementation of DataFrameGroupBy.apply() previously evaluated the supplied function consistently twice on the first group to infer if it is safe to use a fast code path. Particularly for functions with side effects, this was an undesired behavior and may have led to surprises. * Concatenating sparse values When passed DataFrames whose values are sparse, concat will now return a Series or DataFrame with sparse values, rather than a SparseDataFrame . * The .str-accessor performs stricter type checks Due to the lack of more fine-grained dtypes, Series.str so far only checked whether the data was of object dtype. Series.str will now infer the dtype data *within* the Series; in particular, 'bytes'-only data will raise an exception (except for Series.str.decode, Series.str.get, Series.str.len, Series.str.slice). * Categorical dtypes are preserved during groupby Previously, columns that were categorical, but not the groupby key(s) would be converted to object dtype during groupby operations. Pandas now will preserve these dtypes. * Incompatible Index type unions When performing Index.union operations between objects of incompatible dtypes, the result will be a base Index of dtype object. This behavior holds true for unions between Index objects that previously would have been prohibited. The dtype of empty Index objects will now be evaluated before performing union operations rather than simply returning the other Index object. Index.union can now be considered commutative, such that A.union(B) == B.union(A) . * DataFrame groupby ffill/bfill no longer return group labels The methods ffill, bfill, pad and backfill of DataFrameGroupBy <pandas.core.groupby.DataFrameGroupBy> previously included the group labels in the return value, which was inconsistent with other groupby transforms. Now only the filled values are returned. * DataFrame describe on an empty categorical / object column will return top and freq When calling DataFrame.describe with an empty categorical / object column, the 'top' and 'freq' columns were previously omitted, which was inconsistent with the output for non-empty columns. Now the 'top' and 'freq' columns will always be included, with numpy.nan in the case of an empty DataFrame * __str__ methods now call __repr__ rather than vice versa Pandas has until now mostly defined string representations in a Pandas objects's __str__/__unicode__/__bytes__ methods, and called __str__ from the __repr__ method, if a specific __repr__ method is not found. This is not needed for Python3. In Pandas 0.25, the string representations of Pandas objects are now generally defined in __repr__, and calls to __str__ in general now pass the call on to the __repr__, if a specific __str__ method doesn't exist, as is standard for Python. This change is backward compatible for direct usage of Pandas, but if you subclass Pandas objects *and* give your subclasses specific __str__/__repr__ methods, you may have to adjust your __str__/__repr__ methods . * Indexing an IntervalIndex with Interval objects Indexing methods for IntervalIndex have been modified to require exact matches only for Interval queries. IntervalIndex methods previously matched on any overlapping Interval. Behavior with scalar points, e.g. querying with an integer, is unchanged . * Binary ufuncs on Series now align Applying a binary ufunc like numpy.power now aligns the inputs when both are Series . * Categorical.argsort now places missing values at the end Categorical.argsort now places missing values at the end of the array, making it consistent with NumPy and the rest of pandas . * Column order is preserved when passing a list of dicts to DataFrame Starting with Python 3.7 the key-order of dict is guaranteed <https://mail.python.org/pipermail/python-dev/2017-December/151283.html>_. In practice, this has been true since Python 3.6. The DataFrame constructor now treats a list of dicts in the same way as it does a list of OrderedDict, i.e. preserving the order of the dicts. This change applies only when pandas is running on Python>=3.6 . * Increased minimum versions for dependencies * DatetimeTZDtype will now standardize pytz timezones to a common timezone instance * Timestamp and Timedelta scalars now implement the to_numpy method as aliases to Timestamp.to_datetime64 and Timedelta.to_timedelta64, respectively. * Timestamp.strptime will now rise a NotImplementedError * Comparing Timestamp with unsupported objects now returns :pyNotImplemented instead of raising TypeError. This implies that unsupported rich comparisons are delegated to the other object, and are now consistent with Python 3 behavior for datetime objects * Bug in DatetimeIndex.snap which didn't preserving the name of the input Index * The arg argument in pandas.core.groupby.DataFrameGroupBy.agg has been renamed to func * The arg argument in pandas.core.window._Window.aggregate has been renamed to func * Most Pandas classes had a __bytes__ method, which was used for getting a python2-style bytestring representation of the object. This method has been removed as a part of dropping Python2 * The .str-accessor has been disabled for 1-level MultiIndex, use MultiIndex.to_flat_index if necessary * Removed support of gtk package for clipboards * Using an unsupported version of Beautiful Soup 4 will now raise an ImportError instead of a ValueError * Series.to_excel and DataFrame.to_excel will now raise a ValueError when saving timezone aware data. * ExtensionArray.argsort places NA values at the end of the sorted array. * DataFrame.to_hdf and Series.to_hdf will now raise a NotImplementedError when saving a MultiIndex with extention data types for a fixed format. * Passing duplicate names in read_csv will now raise a ValueError + Deprecations * Sparse subclasses The SparseSeries and SparseDataFrame subclasses are deprecated. Their functionality is better-provided by a Series or DataFrame with sparse values. * msgpack format The msgpack format is deprecated as of 0.25 and will be removed in a future version. It is recommended to use pyarrow for on-the-wire transmission of pandas objects. * The deprecated .ix[] indexer now raises a more visible FutureWarning instead of DeprecationWarning . * Deprecated the units=M (months) and units=Y (year) parameters for units of pandas.to_timedelta, pandas.Timedelta and pandas.TimedeltaIndex * pandas.concat has deprecated the join_axes-keyword. Instead, use DataFrame.reindex or DataFrame.reindex_like on the result or on the inputs * The SparseArray.values attribute is deprecated. You can use np.asarray(...) or the SparseArray.to_dense method instead . * The functions pandas.to_datetime and pandas.to_timedelta have deprecated the box keyword. Instead, use to_numpy or Timestamp.to_datetime64 or Timedelta.to_timedelta64. * The DataFrame.compound and Series.compound methods are deprecated and will be removed in a future version . * The internal attributes _start, _stop and _step attributes of RangeIndex have been deprecated. Use the public attributes ~RangeIndex.start, ~RangeIndex.stop and ~RangeIndex.step instead . * The Series.ftype, Series.ftypes and DataFrame.ftypes methods are deprecated and will be removed in a future version. Instead, use Series.dtype and DataFrame.dtypes . * The Series.get_values, DataFrame.get_values, Index.get_values, SparseArray.get_values and Categorical.get_values methods are deprecated. One of np.asarray(..) or ~Series.to_numpy can be used instead . * The 'outer' method on NumPy ufuncs, e.g. np.subtract.outer has been deprecated on Series objects. Convert the input to an array with Series.array first * Timedelta.resolution is deprecated and replaced with Timedelta.resolution_string. In a future version, Timedelta.resolution will be changed to behave like the standard library datetime.timedelta.resolution * read_table has been undeprecated. * Index.dtype_str is deprecated. * Series.imag and Series.real are deprecated. * Series.put is deprecated. * Index.item and Series.item is deprecated. * The default value ordered=None in ~pandas.api.types.CategoricalDtype has been deprecated in favor of ordered=False. When converting between categorical types ordered=True must be explicitly passed in order to be preserved. * Index.contains is deprecated. Use key in index (__contains__) instead . * DataFrame.get_dtype_counts is deprecated. * Categorical.ravel will return a Categorical instead of a np.ndarray + Removal of prior version deprecations/changes * Removed Panel * Removed the previously deprecated sheetname keyword in read_excel * Removed the previously deprecated TimeGrouper * Removed the previously deprecated parse_cols keyword in read_excel * Removed the previously deprecated pd.options.html.border * Removed the previously deprecated convert_objects * Removed the previously deprecated select method of DataFrame and Series * Removed the previously deprecated behavior of Series treated as list-like in ~Series.cat.rename_categories * Removed the previously deprecated DataFrame.reindex_axis and Series.reindex_axis * Removed the previously deprecated behavior of altering column or index labels with Series.rename_axis or DataFrame.rename_axis * Removed the previously deprecated tupleize_cols keyword argument in read_html, read_csv, and DataFrame.to_csv * Removed the previously deprecated DataFrame.from.csv and Series.from_csv * Removed the previously deprecated raise_on_error keyword argument in DataFrame.where and DataFrame.mask * Removed the previously deprecated ordered and categories keyword arguments in astype * Removed the previously deprecated cdate_range * Removed the previously deprecated True option for the dropna keyword argument in SeriesGroupBy.nth * Removed the previously deprecated convert keyword argument in Series.take and DataFrame.take + Performance improvements * Significant speedup in SparseArray initialization that benefits most operations, fixing performance regression introduced in v0.20.0 * DataFrame.to_stata() is now faster when outputting data with any string or non-native endian columns * Improved performance of Series.searchsorted.

These methods now have an axis parameter which determines how the Series or DataFrame will be aligned with the threshold(s). - DataFrame.mask() and Series.mask() now support same keywords as where - drop function can now accept errors keyword to suppress ValueError raised when any of label does not exist in the target data. - Allow conversion of values with dtype datetime64 or timedelta64 to strings using astype(str) - get_dummies function now accepts sparse keyword. If set to True, the return DataFrame is sparse, e.g. SparseDataFrame. - Period now accepts datetime64 as value input. - Allow timedelta string conversion when leading zero is missing from time definition, ie 0:00:00 vs 00:00:00. - Allow Panel.shift with axis='items' - Trying to write an excel file now raises NotImplementedError if the DataFrame has a MultiIndex instead of writing a broken Excel file. - Allow Categorical.add_categories to accept Series or np.array. - Add/delete str/dt/cat accessors dynamically from __dir__. - Add normalize as a dt accessor method. - DataFrame and Series now have _constructor_expanddim property as overridable constructor for one higher dimensionality data. This should be used only when it is really needed - pd.lib.infer_dtype now returns 'bytes' in Python 3 where appropriate. - We introduce a CategoricalIndex, a new type of index object that is useful for supporting indexing with duplicates. This is a container around a Categorical (introduced in v0.15.0) and allows efficient indexing and storage of an index with a large number of duplicated elements. Prior to 0.16.1, setting the index of a DataFrame/Series with a category dtype would convert this to regular object-based Index. - Series, DataFrames, and Panels now have a new method: pandas.DataFrame.sample. The method accepts a specific number of rows or columns to return, or a fraction of the total number or rows or columns. It also has options for sampling with or without replacement, for passing in a column for weights for non-uniform sampling, and for setting seed values to facilitate replication. - The following new methods are accesible via .str accessor to apply the function to each values. + capitalize() + swapcase() + normalize() + partition() + rpartition() + index() + rindex() + translate() - Added StringMethods (.str accessor) to Index - split now takes expand keyword to specify whether to expand dimensionality. return_type is deprecated. * API changes - When passing in an ax to df.plot( ..., ax=ax), the sharex kwarg will now default to False. - Add support for separating years and quarters using dashes, for example 2014-Q1. - pandas.DataFrame.assign now inserts new columns in alphabetical order. Previously the order was arbitrary. - By default, read_csv and read_table will now try to infer the compression type based on the file extension. Set compression=None to restore the previous behavior (no decompression). - The string representation of Index and its sub-classes have now been unified. These will show a single-line display if there are few values; a wrapped multi-line display for a lot of values (but less than display.max_seq_items; if lots of items > display.max_seq_items) will show a truncated display (the head and tail of the data). The formatting for MultiIndex is unchanges (a multi-line wrapped display). The display width responds to the option display.max_seq_items, which is defaulted to 100. * Deprecations - Series.str.split's return_type keyword was removed in favor of expand * Performance Improvements - Improved csv write performance with mixed dtypes, including datetimes by up to 5x - Improved csv write performance generally by 2x - Improved the performance of pd.lib.max_len_string_array by 5-7x * Bug Fixes - Bug where labels did not appear properly in the legend of DataFrame.plot(), passing label= arguments works, and Series indices are no longer mutated. - Bug in json serialization causing a segfault when a frame had zero length. - Bug in read_csv where missing trailing delimiters would cause segfault. - Bug in retaining index name on appending - Bug in scatter_matrix draws unexpected axis ticklabels - Fixed bug in StataWriter resulting in changes to input DataFrame upon save. - Bug in transform causing length mismatch when null entries were present and a fast aggregator was being used - Bug in equals causing false negatives when block order differed - Bug in grouping with multiple pd.Grouper where one is non-time based - Bug in read_sql_table error when reading postgres table with timezone - Bug in DataFrame slicing may not retain metadata - Bug where TimdeltaIndex were not properly serialized in fixed HDFStore - Bug with TimedeltaIndex constructor ignoring name when given another TimedeltaIndex as data. - Bug in DataFrameFormatter._get_formatted_index with not applying max_colwidth to the DataFrame index - Bug in .loc with a read-only ndarray data source - Bug in groupby.apply() that would raise if a passed user defined function either returned only None (for all input). - Always use temporary files in pytables tests - Bug in plotting continuously using secondary_y may not show legend properly. - Bug in DataFrame.plot(kind="hist") results in TypeError when DataFrame contains non-numeric columns - Bug where repeated plotting of DataFrame with a DatetimeIndex may raise TypeError - Bug in setup.py that would allow an incompat cython version to build - Bug in plotting secondary_y incorrectly attaches right_ax property to secondary axes specifying itself recursively. - Bug in Series.quantile on empty Series of type Datetime or Timedelta - Bug in where causing incorrect results when upcasting was required - Bug in FloatArrayFormatter where decision boundary for displaying "small" floats in decimal format is off by one order of magnitude for a given display.precision - Fixed bug where DataFrame.plot() raised an error when both color and style keywords were passed and there was no color symbol in the style strings - Not showing a DeprecationWarning on combining list-likes with an Index - Bug in read_csv and read_table when using skip_rows parameter if blank lines are present. - Bug in read_csv() interprets index_col=True as 1 - Bug in index equality comparisons using == failing on Index/MultiIndex type incompatibility - Bug in which SparseDataFrame could not take nan as a column name - Bug in to_msgpack and read_msgpack zlib and blosc compression support - Bug GroupBy.size doesn't attach index name properly if grouped by TimeGrouper - Bug causing an exception in slice assignments because length_of_indexer returns wrong results - Bug in csv parser causing lines with initial whitespace plus one non-space character to be skipped. - Bug in C csv parser causing spurious NaNs when data started with newline followed by whitespace. - Bug causing elements with a null group to spill into the final group when grouping by a Categorical - Bug where .iloc and .loc behavior is not consistent on empty dataframes - Bug in invalid attribute access on a TimedeltaIndex incorrectly raised ValueError instead of AttributeError - Bug in unequal comparisons between categorical data and a scalar, which was not in the categories (e.g. Series(Categorical(list("abc"), ordered=True)) > "d". This returned False for all elements, but now raises a TypeError. Equality comparisons also now return False for == and True for !=. - Bug in DataFrame __setitem__ when right hand side is a dictionary - Bug in where when dtype is datetime64/timedelta64, but dtype of other is not - Bug in MultiIndex.sortlevel() results in unicode level name breaks - Bug in which groupby.transform incorrectly enforced output dtypes to match input dtypes. - Bug in DataFrame constructor when columns parameter is set, and data is an empty list - Bug in bar plot with log=True raises TypeError if all values are less than 1 - Bug in horizontal bar plot ignores log=True - Bug in PyTables queries that did not return proper results using the index - Bug where dividing a dataframe containing values of type Decimal by another Decimal would raise. - Bug where using DataFrames asfreq would remove the name of the index. - Bug causing extra index point when resample BM/BQ - Changed caching in AbstractHolidayCalendar to be at the instance level rather than at the class level as the latter can result in unexpected behaviour. - Fixed latex output for multi-indexed dataframes - Bug causing an exception when setting an empty range using DataFrame.loc - Bug in hiding ticklabels with subplots and shared axes when adding a new plot to an existing grid of axes - Bug in transform and filter when grouping on a categorical variable - Bug in transform when groups are equal in number and dtype to the input index - Google BigQuery connector now imports dependencies on a per-method basis. - Updated BigQuery connector to no longer use deprecated oauth2client.tools.run() - Bug in subclassed DataFrame.

We refer users to external packages like seaborn, pandas-qt and rpy2 for similar or equivalent functionality * New features - Inspired by dplyr's mutate verb, DataFrame has a new assign method. - Added SparseSeries.to_coo and SparseSeries.from_coo methods for converting to and from scipy.sparse.coo_matrix instances. - Following new methods are accesible via .str accessor to apply the function to each values. This is intended to make it more consistent with standard methods on strings: isalnum(), isalpha(), isdigit(), isdigit(), isspace(), islower(), isupper(), istitle(), isnumeric(), isdecimal(), find(), rfind(), ljust(), rjust(), zfill() - Reindex now supports method='nearest' for frames or series with a monotonic increasing or decreasing index. - The read_excel() function's sheetname argument now accepts a list and None, to get multiple or all sheets respectively. If more than one sheet is specified, a dictionary is returned. - Allow Stata files to be read incrementally with an iterator; support for long strings in Stata files. - Paths beginning with ~ will now be expanded to begin with the user's home directory. - Added time interval selection in get_data_yahoo. - Added Timestamp.to_datetime64() to complement Timedelta.to_timedelta64(). - tseries.frequencies.to_offset() now accepts Timedelta as input. - Lag parameter was added to the autocorrelation method of Series, defaults to lag-1 autocorrelation. - Timedelta will now accept nanoseconds keyword in constructor. - SQL code now safely escapes table and column names. - Added auto-complete for Series.str.<tab>, Series.dt.<tab> and Series.cat.<tab>. - Index.get_indexer now supports method='pad' and method='backfill' even for any target array, not just monotonic targets. - Index.asof now works on all index types. - A verbose argument has been augmented in io.read_excel(), defaults to False. Set to True to print sheet names as they are parsed. - Added days_in_month (compatibility alias daysinmonth) property to Timestamp, DatetimeIndex, Period, PeriodIndex, and Series.dt. - Added decimal option in to_csv to provide formatting for non-'.' decimal separators - Added normalize option for Timestamp to normalized to midnight - Added example for DataFrame import to R using HDF5 file and rhdf5 library. * Backwards incompatible API changes - In v0.16.0, we are restoring the API to match that of datetime.timedelta. Further, the component values are still available through the .components accessor. This affects the .seconds and .microseconds accessors, and removes the .hours, .minutes, .milliseconds accessors. These changes affect TimedeltaIndex and the Series .dt accessor as well. - The behavior of a small sub-set of edge cases for using .loc have changed. Furthermore we have improved the content of the error messages that are raised: + Slicing with .loc where the start and/or stop bound is not found in the index is now allowed; this previously would raise a KeyError. This makes the behavior the same as .ix in this case. This change is only for slicing, not when indexing with a single label. + Allow slicing with float-like values on an integer index for .ix. Previously this was only enabled for .loc: + Provide a useful exception for indexing with an invalid type for that index when using .loc. For example trying to use .loc on an index of type DatetimeIndex or PeriodIndex or TimedeltaIndex, with an integer (or a float). - In prior versions, Categoricals that had an unspecified ordering (meaning no ordered keyword was passed) were defaulted as ordered Categoricals. Going forward, the ordered keyword in the Categorical constructor will default to False. Ordering must now be explicit. Furthermore, previously you *could* change the ordered attribute of a Categorical by just setting the attribute, e.g. cat.ordered=True; This is now deprecated and you should use cat.as_ordered() or cat.as_unordered(). These will by default return a **new** object and not modify the existing object. - Index.duplicated now returns np.array(dtype=bool) rather than Index(dtype=object) containing bool values. - DataFrame.to_json now returns accurate type serialisation for each column for frames of mixed dtype - DatetimeIndex, PeriodIndex and TimedeltaIndex.summary now output the same format. - TimedeltaIndex.freqstr now output the same string format as DatetimeIndex. - Bar and horizontal bar plots no longer add a dashed line along the info axis. The prior style can be achieved with matplotlib's axhline or axvline methods. - Series accessors .dt, .cat and .str now raise AttributeError instead of TypeError if the series does not contain the appropriate type of data. This follows Python's built-in exception hierarchy more closely and ensures that tests like hasattr(s, 'cat') are consistent on both Python 2 and 3. - Series now supports bitwise operation for integral types. Previously even if the input dtypes were integral, the output dtype was coerced to bool. - During division involving a Series or DataFrame, 0/0 and 0//0 now give np.nan instead of np.inf. - Series.values_counts and Series.describe for categorical data will now put NaN entries at the end. - Series.describe for categorical data will now give counts and frequencies of 0, not NaN, for unused categories - Due to a bug fix, looking up a partial string label with DatetimeIndex.asof now includes values that match the string, even if they are after the start of the partial string label. Old behavior: * Deprecations - The rplot trellis plotting interface is deprecated and will be removed in a future version. We refer to external packages like seaborn for similar but more refined functionality. - The pandas.sandbox.qtpandas interface is deprecated and will be removed in a future version. We refer users to the external package pandas-qt. - The pandas.rpy interface is deprecated and will be removed in a future version. Similar functionaility can be accessed thru the rpy2 project - Adding DatetimeIndex/PeriodIndex to another DatetimeIndex/PeriodIndex is being deprecated as a set-operation. This will be changed to a TypeError in a future version. .union() should be used for the union set operation. - Subtracting DatetimeIndex/PeriodIndex from another DatetimeIndex/PeriodIndex is being deprecated as a set-operation. This will be changed to an actual numeric subtraction yielding a TimeDeltaIndex in a future version. .difference() should be used for the differencing set operation. * Removal of prior version deprecations/changes - DataFrame.pivot_table and crosstab's rows and cols keyword arguments were removed in favor of index and columns - DataFrame.to_excel and DataFrame.to_csv cols keyword argument was removed in favor of columns - Removed convert_dummies in favor of get_dummies - Removed value_range in favor of describe * Performance Improvements - Fixed a performance regression for .loc indexing with an array or list-like. - DataFrame.to_json 30x performance improvement for mixed dtype frames. - Performance improvements in MultiIndex.duplicated by working with labels instead of values - Improved the speed of nunique by calling unique instead of value_counts - Performance improvement of up to 10x in DataFrame.count and DataFrame.dropna by taking advantage of homogeneous/heterogeneous dtypes appropriately - Performance improvement of up to 20x in DataFrame.count when using a MultiIndex and the level keyword argument - Performance and memory usage improvements in merge when key space exceeds int64 bounds - Performance improvements in multi-key groupby - Performance improvements in MultiIndex.sortlevel - Performance and memory usage improvements in DataFrame.duplicated - Cythonized Period - Decreased memory usage on to_hdf * Bug Fixes - Changed .to_html to remove leading/trailing spaces in table body - Fixed issue using read_csv on s3 with Python 3 - Fixed compatibility issue in DatetimeIndex affecting architectures where numpy.int_ defaults to numpy.int32 - Bug in Panel indexing with an object-like - Bug in the returned Series.dt.components index was reset to the default index - Bug in Categorical.__getitem__/__setitem__ with listlike input getting incorrect results from indexer coercion - Bug in partial setting with a DatetimeIndex - Bug in groupby for integer and datetime64 columns when applying an aggregator that caused the value to be changed when the number was sufficiently large - Fixed bug in to_sql when mapping a Timestamp object column (datetime column with timezone info) to the appropriate sqlalchemy type. - Fixed bug in to_sql dtype argument not accepting an instantiated SQLAlchemy type. - Bug in .loc partial setting with a np.datetime64 - Incorrect dtypes inferred on datetimelike looking Series & on .xs slices - Items in Categorical.unique() (and s.unique() if s is of dtype category) now appear in the order in which they are originally found, not in sorted order. This is now consistent with the behavior for other dtypes in pandas. - Fixed bug on big endian platforms which produced incorrect results in StataReader. - Bug in MultiIndex.has_duplicates when having many levels causes an indexer overflow - Bug in pivot and unstack where nan values would break index alignment - Bug in left join on multi-index with sort=True or null values. - Bug in MultiIndex where inserting new keys would fail. - Bug in groupby when key space exceeds int64 bounds. - Bug in unstack with TimedeltaIndex or DatetimeIndex and nulls. - Bug in rank where comparing floats with tolerance will cause inconsistent behaviour. - Fixed character encoding bug in read_stata and StataReader when loading data from a URL. - Bug in adding offsets.Nano to other offets raises TypeError - Bug in DatetimeIndex iteration, related to, fixed in - Bugs in resample around DST transitions. This required fixing offset classes so they behave correctly on DST transitions. - Bug in binary operator method (eg .mul()) alignment with integer levels. - Bug in boxplot, scatter and hexbin plot may show an unnecessary warning - Bug in subplot with layout kw may show unnecessary warning - Bug in using grouper functions that need passed thru arguments (e.g. axis), when using wrapped function (e.g. fillna), - DataFrame now properly supports simultaneous copy and dtype arguments in constructor - Bug in read_csv when using skiprows on a file with CR line endings with the c engine. - isnull now detects NaT in PeriodIndex - Bug in groupby .nth() with a multiple column groupby - Bug in DataFrame.where and Series.where coerce numerics to string incorrectly - Bug in DataFrame.where and Series.where raise ValueError when string list-like is passed. - Accessing Series.str methods on with non-string values now raises TypeError instead of producing incorrect results - Bug in DatetimeIndex.__contains__ when index has duplicates and is not monotonic increasing - Fixed division by zero error for Series.kurt() when all values are equal - Fixed issue in the xlsxwriter engine where it added a default 'General' format to cells if no other format wass applied. This prevented other row or column formatting being applied. - Fixes issue with index_col=False when usecols is also specified in read_csv. - Bug where wide_to_long would modify the input stubnames list - Bug in to_sql not storing float64 values using double precision. - SparseSeries and SparsePanel now accept zero argument constructors (same as their non-sparse counterparts). - Regression in merging Categorical and object dtypes - Bug in read_csv with buffer overflows with certain malformed input files - Bug in groupby MultiIndex with missing pair - Fixed bug in Series.groupby where grouping on MultiIndex levels would ignore the sort argument - Fix bug in DataFrame.Groupby where sort=False is ignored in the case of Categorical columns. - Fixed bug with reading CSV files from Amazon S3 on python 3 raising a TypeError - Bug in the Google BigQuery reader where the 'jobComplete' key may be present but False in the query results - Bug in Series.values_counts with excluding NaN for categorical type Series with dropna=True - Fixed mising numeric_only option for DataFrame.std/var/sem - Support constructing Panel or Panel4D with scalar data - Series text representation disconnected from `max_rows`/`max_columns`. - Series number formatting inconsistent when truncated. - A Spurious SettingWithCopy Warning was generated when setting a new item in a frame in some cases ------------------------------------------------------------------- Mon Jan 12 13:46:26 UTC 2015 - toddrme2178@gmail.com - update to version 0.15.2: * API changes: - Indexing in MultiIndex beyond lex-sort depth is now supported, though a lexically sorted index will have a better performance. (GH2646) - Bug in unique of Series with category dtype, which returned all categories regardless whether they were "used" or not (see GH8559 for the discussion). Previous behaviour was to return all categories. - Series.all and Series.any now support the level and skipna parameters. Series.all, Series.any, Index.all, and Index.any no longer support the out and keepdims parameters, which existed for compatibility with ndarray. Various index types no longer support the all and any aggregation functions and will now raise TypeError. (GH8302). - Allow equality comparisons of Series with a categorical dtype and object dtype; previously these would raise TypeError (GH8938) - Bug in NDFrame: conflicting attribute/column names now behave consistently between getting and setting. Previously, when both a column and attribute named y existed, data.y would return the attribute, while data.y = z would update the column (GH8994) - Timestamp('now') is now equivalent to Timestamp.now() in that it returns the local time rather than UTC. Also, Timestamp('today') is now equivalent to Timestamp.today() and both have tz as a possible argument.

See here for limitations of categorical variables exported to Stata data files. - Added flag order_categoricals to StataReader and read_stata to select whether to order imported categorical data (GH8836). See here for more information on importing categorical variables from Stata data files. - Added ability to export Categorical data to to/from HDF5 (GH7621). Queries work the same as if it was an object array. However, the category dtyped data is stored in a more efficient manner. See here for an example and caveats w.r.t. prior versions of pandas. - Added support for searchsorted() on Categorical class (GH8420). - Added the ability to specify the SQL type of columns when writing a DataFrame to a database (GH8778). For example, specifying to use the sqlalchemy String type instead of the default Text type for string columns. - Series.all and Series.any now support the level and skipna parameters (GH8302). - Panel now supports the all and any aggregation functions. (GH8302). - Added support for utcfromtimestamp(), fromtimestamp(), and combine() on Timestamp class (GH5351). - Added Google Analytics (pandas.io.ga) basic documentation (GH8835). - Timedelta arithmetic returns NotImplemented in unknown cases, allowing extensions by custom classes (GH8813). - Timedelta now supports arithemtic with numpy.ndarray objects of the appropriate dtype (numpy 1.8 or newer only) (GH8884). - Added Timedelta.to_timedelta64() method to the public API (GH8884). - Added gbq.generate_bq_schema() function to the gbq module (GH8325). - Series now works with map objects the same way as generators (GH8909). - Added context manager to HDFStore for automatic closing (GH8791). - to_datetime gains an exact keyword to allow for a format to not require an exact match for a provided format string (if its False). exact defaults to True (meaning that exact matching is still the default) (GH8904) - Added axvlines boolean option to parallel_coordinates plot function, determines whether vertical lines will be printed, default is True - Added ability to read table footers to read_html (GH8552). - to_sql now infers datatypes of non-NA values for columns that contain NA values and have dtype object (GH8778). * Performance: - Reduce memory usage when skiprows is an integer in read_csv (GH8681) - Performance boost for to_datetime conversions with a passed format=, and the exact=False (GH8904) * Bug fixes: - Bug in concat of Series with category dtype which were coercing to object. (GH8641) - Bug in Timestamp-Timestamp not returning a Timedelta type and datelike-datelike ops with timezones (GH8865) - Made consistent a timezone mismatch exception (either tz operated with None or incompatible timezone), will now return TypeError rather than ValueError (a couple of edge cases only), (GH8865) - Bug in using a pd.Grouper(key=...) with no level/axis or level only (GH8795, GH8866) - Report a TypeError when invalid/no paramaters are passed in a groupby (GH8015) - Bug in packaging pandas with py2app/cx_Freeze (GH8602, GH8831) - Bug in groupby signatures that didn’t include *args or **kwargs (GH8733). - io.data.Options now raises RemoteDataError when no expiry dates are available from Yahoo and when it receives no data from Yahoo (GH8761), (GH8783). - Unclear error message in csv parsing when passing dtype and names and the parsed data is a different data type (GH8833) - Bug in slicing a multi-index with an empty list and at least one boolean indexer (GH8781) - io.data.Options now raises RemoteDataError when no expiry dates are available from Yahoo (GH8761). - Timedelta kwargs may now be numpy ints and floats (GH8757). - Fixed several outstanding bugs for Timedelta arithmetic and comparisons (GH8813, GH5963, GH5436). - sql_schema now generates dialect appropriate CREATE TABLE statements (GH8697) - slice string method now takes step into account (GH8754) - Bug in BlockManager where setting values with different type would break block integrity (GH8850) - Bug in DatetimeIndex when using time object as key (GH8667) - Bug in merge where how='left' and sort=False would not preserve left frame order (GH7331) - Bug in MultiIndex.reindex where reindexing at level would not reorder labels (GH4088) - Bug in certain operations with dateutil timezones, manifesting with dateutil 2.3 (GH8639) - Regression in DatetimeIndex iteration with a Fixed/Local offset timezone (GH8890) - Bug in to_datetime when parsing a nanoseconds using the %f format (GH8989) - io.data.Options now raises RemoteDataError when no expiry dates are available from Yahoo and when it receives no data from Yahoo (GH8761), (GH8783). - Fix: The font size was only set on x axis if vertical or the y axis if horizontal.
