- Bug in :meth:`DataFrame.corr` where numerical precision errors resulted in correlations above ``1.0`` (:issue:`61120`)

I think it's worth stating that this raises a TypeError now, rather than returning incorrect results. Also IIUC, we always raise a TypeError, regardless of the presence of NaT. So maybe

Suggested change
- Bug in :meth:`DataFrame.cov` where presence of ``NaT`` in columns could lead to incorrect results or errors (:issue:`53115`)
:meth:`DataFrame.cov` raises a ``TypeError`` instead of returning potentially incorrect results or other errors (:issue:`53115`).

- Bug in :meth:`DataFrame.quantile` where the column type was not preserved when ``numeric_only=True`` with a list-like ``q`` produced an empty result (:issue:`59035`)
- Bug in :meth:`Series.dot` returning ``object`` dtype for :class:`ArrowDtype` and nullable-dtype data (:issue:`61375`)
- Bug in ``np.matmul`` with :class:`Index` inputs raising a ``TypeError`` (:issue:`57079`)
