- Add marching cubes display of head if :func:`mne.bem.make_scalp_surfaces` has not computed or the recon-all hasn't finished (:gh:`10202` by `Alex Rockhill`_)

- :func:`mne.gui.coregistration` now uses the proper widget style for push buttons, making for a more native feel of the application (:gh:`10220` by `Richard Höchenberger`_ and `Guillaume Favelier`_)

- :class:`mne.coreg.Coregistration`, :func:`mne.scale_bem`, and :func:`mne.scale_mri` gained a new parameter, ``on_defects``, controlling how to handle topological defects (:gh:`10230`, :gh:`10249` by `Richard Höchenberger`_)

- :class:`mne.coreg.Coregistration` gained a new attribute, ``fiducials``, allowing for convenient retrieval of the MRI fiducial points (:gh:`10243`, by `Richard Höchenberger`_)

- Added plotting points to represent contacts on the max intensity projection plot for :func:`mne.gui.locate_ieeg` (:gh:`10212` by `Alex Rockhill`_)

- Add lines in 3D and on the maximum intensity projection when more than two electrode contacts are selected to aid in identifying that contact for :func:`mne.gui.locate_ieeg` (:gh:`10212` by `Alex Rockhill`_)

- Add a ``block`` parameter to :class:`mne.viz.Brain` and the UI of :class:`mne.coreg.Coregistration` to prevent the windows from closing immediately when running in a non-interactive Python session (:gh:`10222` by `Guillaume Favelier`_)

- All methods of :class:`mne.Report` with a ``tags`` parameter now also accept a single tag passed as a string (previously, you needed to pass a tuple of strings, even for a single tag) (:gh:`10183`, by `Richard Höchenberger`_)

API changes
~~~~~~~~~~~
- The default browser for :meth:`raw.plot() <mne.io.Raw.plot>`, :meth:`epochs.plot() <mne.Epochs.plot>`, and :meth:`ica.plot_sources() <mne.preprocessing.ICA.plot_sources>` has been changed to the ``'qt'`` backend on systems where `mne_qt_browser <https://github.com/mne-tools/mne-qt-browser>`__ is installed. To change back to matplotlib within a session, you can use :func:`mne.viz.set_browser_backend('matplotlib') <mne.viz.set_browser_backend>`. To set it permanently on your system, you can use :func:`mne.set_config('MNE_BROWSER_BACKEND', 'matplotlib') <mne.set_config>` (:gh:`9960` by `Martin Schulz`_ and `Eric Larson`_)

- ``mne.Info.pick_channels`` has been deprecated. Use ``inst.pick_channels`` to pick channels from :class:`~mne.io.Raw`, :class:`~mne.Epochs`, and :class:`~mne.Evoked`. Use :func:`mne.pick_info` to pick channels from :class:`mne.Info` (:gh:`10039` by `Mathieu Scheltienne`_)

- All :func:`data_path <mne.datasets.sample.data_path>` functions now return :class:`python:pathlib.Path` objects rather than strings. Support for string concatenation with plus (``+``) is thus deprecated and will be removed in 1.2, use the forward-slash ``/`` operator instead (:gh:`10348` by `Eric Larson`_)

- Argument ``event_list`` has been deprecated in favor of ``events`` in :func:`mne.write_events` (:gh:`10056` by `Mathieu Scheltienne`_)

- ``mne.preprocessing.annotate_flat`` has been deprecated in favor of :func:`mne.preprocessing.annotate_amplitude`, that covers both minimum and maximum peak-to-peak variation. (:gh:`10143` by `Mathieu Scheltienne`_)

- The ``max_ori_out`` parameter of :func:`mne.beamformer.apply_lcmv` and related functions is being removed as only signed estimates are supported. ``abs(stc)`` can be used to obtain unsigned estimates (:gh:`10366` by `Eric Larson`_)

- The ``verbose`` attribute of classes (e.g., :class:`mne.io.Raw`, `mne.Epochs`, etc.) has been deprecated. Explicitly pass ``verbose`` to methods as necessary instead. (:gh:`10267` by `Eric Larson`_)

- In :func:`mne.viz.set_browser_backend`, the `mne-qt-browser <https://github.com/mne-tools/mne-qt-browser>`__-based backend is now called ``'qt'`` rather than ``'pyqtgraph'`` for simplicity (:gh:`10323` by `Eric Larson`_)

Dependencies
~~~~~~~~~~~~
Numerous external dependencies that used to be bundled with MNE-Python are now
not shipped with the package anymore and will instead be retrieved
automatically from their official sources when you install MNE-Python. This
simplifies MNE-Python maintenance and keeps the package smaller. The following
new dependencies have been added:

- `Jinja2`_ (replaces ``Tempita``, which is not maintained anymore; :gh:`10211` by `Richard Höchenberger`_)
