2.3 compatibility tracker

[cmp0xff]

This is the list of things that are in pandas 2.3 release notes that need to be addressed in pandas-stubs. I have removed the sections Performance improvements and Bug fixes.

PR's welcome. If you do a PR, check off the item and put a link to the PR that closed it. One PR can address multiple issues.

Some of these may already have been taken care of, so if so, check them off and indicate with a comment such as "previously complete"

Upcoming changes in pandas 3.0

• Dedicated string data type by default
• Copy-on-Write

Enhancements

• pandas.api.interchange.from_dataframe now uses the PyCapsule Interface <https://arrow.apache.org/docs/format/CDataInterface/PyCapsuleInterface.html>_ if available, only falling back to the Dataframe Interchange Protocol if that fails (ENH: pandas.api.interchange.from_dataframe now uses the Arrow PyCapsule Interface if available, only falling back to the Dataframe Interchange Protocol if that fails pandas#60739)
• The semantics for the copy keyword in __array__ methods (i.e. called
  when using np.array() or np.asarray() on pandas objects) has been
  updated to work correctly with NumPy >= 2 (COMPAT: Utilize copy keyword in __array__ pandas#57739)
  • Irrelevant to stubs
• Series.str.decode result now has StringDtype when future.infer_string is True (ENH(string dtype): Make str.decode return str dtype pandas#60709)
• ~Series.to_hdf and ~DataFrame.to_hdf now round-trip with StringDtype (ENH: Enable pytables to round-trip with StringDtype pandas#60663)
• Improved repr of .NumpyExtensionArray to account for NEP51 (DEPS: Update NumpyExtensionArray repr for NEP51 pandas#61085)
• The Series.str.decode has gained the argument dtype to control the dtype of the result (ENH: Add dtype argument to str.decode pandas#60940)
• The ~Series.cumsum, ~Series.cummin, and ~Series.cummax reductions are now implemented for StringDtype columns (ENH: Implement cum* methods for PyArrow strings pandas#60633)
• The ~Series.sum reduction is now implemented for StringDtype columns (String dtype: implement sum reduction pandas#59853)

Deprecations

• Deprecated allowing non-bool values for na in .str.contains, .str.startswith, and .str.endswith for dtypes that do not already disallow these (DEPR (string): non-bool na for obj.str.contains pandas#59615)
• Deprecated the "pyarrow_numpy" storage option for StringDtype (String dtype: deprecate the pyarrow_numpy storage option pandas#60152)
  • TYP: StringDtype #1603

Most of them are not something we can address in the stubs.
The aggregation methods are already under the pd.Series[str] so they are working, unless you want very specific tests but I would argue that we can't differentiate pd.Series[str] and pd.Series[pd.StringDType] but otherwise please let me know and I will look into it.

If that's the case, edit the description above, and use a strikethrough to remove them.
