* Thu May 09 2024 Matej Cepl - Skip build on Python 3.10 ... too many dependencies are missing.
* Tue Apr 30 2024 Ben Greiner - Update to 2.2.2
* Pandas 2.2.2 is now compatible with numpy 2.0
* Pandas 2.2.2 is the first version of pandas that is generally compatible with the upcoming numpy 2.0 release, and wheels for pandas 2.2.2 will work with both numpy 1.x and 2.x. 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 04 2024 Ben Greiner - 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

* The DeprecationWarning that was raised when pandas was imported without PyArrow being installed has been removed. 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)- Release notes for 2.2.0

* Fixed regression in DataFrame.astype() with dtype=str failing to convert NaN in categorical columns (GH41797)- Unpack some files required for testing
* Mon May 03 2021 Arun Persaud - update to version 1.2.4:
* Fixed regressions + Fixed regression in DataFrame.sum() when min_count greater than the DataFrame shape was passed resulted in a ValueError (GH39738) + Fixed regression in DataFrame.to_json() raising AttributeError when run on PyPy (GH39837) + Fixed regression in (in)equality comparison of pd.NaT with a non-datetimelike numpy array returning a scalar instead of an array (GH40722) + Fixed regression in DataFrame.where() not returning a copy in the case of an all True condition (GH39595) + Fixed regression in DataFrame.replace() raising IndexError when regex was a multi-key dictionary (GH39338) + Fixed regression in repr of floats in an object column not respecting float_format when printed in the console or outputted through DataFrame.to_string(), DataFrame.to_html(), and DataFrame.to_latex() (GH40024) + Fixed regression in NumPy ufuncs such as np.add not passing through all arguments for DataFrame (GH40662)
* Wed Mar 03 2021 Arun Persaud - update to version 1.2.3:
* Fixed regressions + Fixed regression in to_excel() raising KeyError when giving duplicate columns with columns attribute (GH39695) + Fixed regression in nullable integer unary ops propagating mask on assignment (GH39943) + Fixed regression in DataFrame.__setitem__() not aligning DataFrame on right-hand side for boolean indexer (GH39931) + Fixed regression in to_json() failing to use compression with URL-like paths that are internally opened in binary mode or with user-provided file objects that are opened in binary mode (GH39985) + Fixed regression in Series.sort_index() and DataFrame.sort_index(), which exited with an ungraceful error when having kwarg ascending=None passed. Passing ascending=None is still considered invalid, and the improved error message suggests a proper usage (ascending must be a boolean or a list-like of boolean) (GH39434) + Fixed regression in DataFrame.transform() and Series.transform() giving incorrect column labels when passed a dictionary with a mix of list and non-list values (GH40018)

* WARNING: The xlwt package for writing old-style .xls excel files is no longer maintained. 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. Nobody wants to pull in all of those packages by default.- Remove pandas-pytest.ini- Rework test deselection- Limit to 4 pytest-xdist workers, as collection consumes a lot of memory
