Fix bug in :func:`mne.decoding.TimeFrequency` that prevented cloning if constructor arguments were modified (:gh:`11004` by :newcontrib:`Daniel Carlström Schad`)
Fix bug in repr of decoding estimator classes (e.g., :class:`mne.decoding.SlidingEstimator`) where the parameters where not stored in the result string but instead just printed to sys.stdout (:gh:`11190` by :newcontrib:`Dominik Wetzel`)
Document height and weight keys of subject_info entry in :class:`mne.Info` (:gh:`11019` by :newcontrib:`Sena Er`)

Fix bug in :func:`mne.minimum_norm.apply_inverse_epochs` where the average EEG projector was not checked properly (:gh:`11182` by `Eric Larson`_)
Fix bug in :func:`mne.viz.plot_filter` when plotting filters created using output='ba' mode with compensation turned on. (:gh:`11040` by `Marian Dovgialo`_)
Fix bugs in documentation of surface :class:`~mne.SourceSpaces` (:gh:`11171` by `Eric Larson`_)

Fix bug in :func:`mne.io.read_raw_bti` where EEG, EMG, and H/VEOG channels were not detected properly, and many non-ECG channels were called ECG. The logic has been improved, and any channels of unknown type are now labeled as misc (:gh:`11102` by `Eric Larson`_)

The duration of raw data sometimes wasn't displayed correctly in Jupyter notebooks by omitting fractions of a second. We now always round up to the next full second so a duration of less than 1 second will not be displayed as a duration of zero anymore (:gh:`11203` by `Richard Höchenberger`_)

API changes

In :meth:`mne.Evoked.plot`, the default value of the spatial_colors parameter has been changed to 'auto', which will use spatial colors if channel locations are available (:gh:`11201` by :newcontrib:`Hüseyin Orkun Elmas` and `Daniel McCloy`_)
Starting with this release we now follow the Python convention of using FutureWarning instead of DeprecationWarning to signal user-facing changes to our API (:gh:`11120` by `Daniel McCloy`_)
The names parameter of :func:`mne.viz.plot_arrowmap` and :func:`mne.viz.plot_regression_weights` has been deprecated; sensor names will be automatically drawn from the info_from or model parameter (respectively), and can be hidden, shown, or altered via the show_names parameter (:gh:`11123` by `Daniel McCloy`_)
The bands parameter of :meth:`mne.Epochs.plot_psd_topomap` now accepts :class:`dict` input; legacy :class:`tuple` input is supported, but discouraged for new code (:gh:`11050` by `Daniel McCloy`_)
The :func:`mne.head_to_mri` new function parameter kind default will change from 'ras' to 'mri' (:gh:`11185` by `Eric Larson`_)

New classes :class:`~mne.time_frequency.Spectrum` and :class:`~mne.time_frequency.EpochsSpectrum`, created via new methods :meth:`Raw.compute_psd()<mne.io.Raw.compute_psd>`, :meth:`Epochs.compute_psd()<mne.Epochs.compute_psd>`, and :meth:`Evoked.compute_psd()<mne.Evoked.compute_psd>` (:gh:`10184` by `Daniel McCloy`_)
Functions/methods for plotting topomaps now have more consistent signatures; most have gained parameters for finer control of the topomap image and/or colorbar. See docstrings for details (:gh:`11123` by `Daniel McCloy`_)
In :func:`mne.viz.plot_topomap`, passing axes=None will now create a new :class:`~matplotlib.figure.Figure` instead of plotting into the current axes (:gh:`11123` by `Daniel McCloy`_)
In :func:`mne.viz.plot_topomap`, the parameter show_names has been deprecated, use the names parameter instead (:gh:`11123` by `Daniel McCloy`_)
In :func:`mne.viz.plot_topomap`, :func:`~mne.viz.plot_tfr_topomap`, :func:`~mne.viz.plot_evoked_topomap`, and related class methods :meth:`mne.Covariance.plot_topomap`, :meth:`mne.Evoked.plot_topomap`, and :meth:`mne.time_frequency.AverageTFR.plot_topomap`: the parameters vmin and vmax are deprecated in favor of vlim, for consistency with other plot_topomap functions and methods (:gh:`11123` by `Daniel McCloy`_)
In :func:`mne.viz.plot_tfr_topomap`, :func:`~mne.viz.plot_evoked_topomap`, and related class methods :meth:`mne.Covariance.plot_topomap`, :meth:`mne.Evoked.plot_topomap`, and :meth:`mne.time_frequency.AverageTFR.plot_topomap`: the title parameter has been deprecated; use matplotlib's :meth:`fig.suptitle()<matplotlib.figure.Figure.suptitle>` instead (:gh:`11123` by `Daniel McCloy`_)
In functions/methods for plotting topomaps, the outlines='skirt' option is deprecated; use sphere='eeglab' for similar functionality (:gh:`11123` by `Daniel McCloy`_)
The mne.epochs.add_channels_epochs function has been deprecated in favor of :meth:`epochs.add_channels <mne.Epochs.add_channels>` (:gh:`11180` by `Eric Larson`_)
The PSD functions that operate on Raw/Epochs/Evoked instances (mne.time_frequency.psd_welch and mne.time_frequency.psd_multitaper) are deprecated; for equivalent functionality create :class:`~mne.time_frequency.Spectrum` or :class:`~mne.time_frequency.EpochsSpectrum` objects instead and then run spectrum.get_data(return_freqs=True) (:gh:`10184` by `Daniel McCloy`_)
Added new class :class:`mne.preprocessing.EOGRegression` to allow more flexibility when using regression to reduce EOG artifacts (:gh:`11046` by `Marijn van Vliet`_)
New parameter exclude added to :func:`mne.preprocessing.regress_artifact` to prevent regression from being applied to certain channels (:gh:`11046` by `Marijn van Vliet`_)
