 - Inform the user about channel discrepancy between provided info, forward operator, and/or covariance matrices in :func:`mne.beamformer.make_lcmv` (:gh:`12238` by :newcontrib:`Nikolai Kapralov`)
 - We added type hints for the return values of :func:`mne.read_evokeds` and :func:`mne.io.read_raw`. Development environments like VS Code or PyCharm will now provide more help when using these functions in your code. (:gh:`12250` by `Richard Höchenberger`_ and `Eric Larson`_)
 - Add ``method="polyphase"`` to :meth:`mne.io.Raw.resample` and related functions to allow resampling using :func:`scipy.signal.upfirdn` (:gh:`12268` by `Eric Larson`_)
+- The package build backend was switched from ``setuptools`` to ``hatchling``. This will only affect users who build and install MNE-Python from source. (:gh:`12269` by `Richard Höchenberger`_)
