- Bug in comparison between object with :class:`ArrowDtype` and incompatible-dtyped (e.g. string vs bool) incorrectly raising instead of returning all-``False`` (for ``==``) or all-``True`` (for ``!=``) (:issue:`59505`)
- Bug in constructing pandas data structures when passing into ``dtype`` a string of the type followed by ``[pyarrow]`` while PyArrow is not installed would raise ``NameError`` rather than ``ImportError`` (:issue:`57928`)
- Bug in various :class:`DataFrame` reductions for pyarrow temporal dtypes returning incorrect dtype when result was null (:issue:`59234`)
- Bug in :meth:`Series.map` and :meth:`Series.apply` where applying functions to a Series with an :class:`Int32Dtype` or other :class:`ExtensionDtype` would convert elements to float and ``pd.NA`` to ``np.nan``, instead of preserving the original types (:issue:`60766`)
