Bugfixes#

Handle scenario where an Eyelink recording switched from binocular to monocular mode during a trial by Scott Huberty (#12847)
Fix bug with mne.io.read_raw_egi() where info["dev_head_t"] was an identity matrix instead of None, by Eric Larson. (#13112)
Read Nihon Kohden annotation file accurately (using sublog parsing), by Tom Ma. (#13251)
Fix bug with mne.open_report() not working with old saved files, by Eric Larson. (#13341)
Restore clipping=3 in plot() (which was mistakenly changed to 1.5) to reduce excessive clipping of raw data, by Clemens Brunner. (#13354)
Make read_raw_eyelink() work with ASCII files collected with Eye Event Mode set to “HREF” by Scott Huberty. (#13357)
model parameter of mne.decoding.LinearModel will not be modified, use model_ attribute to access the fitted model. To be compatible with all MNE-Python versions you can use getattr(clf, "model_", getattr(clf, "model")) The provided model is expected to be a supervised predictor, i.e. classifier or regressor (or sklearn.multiclass.OneVsRestClassifier), otherwise an error will be raised. by Gennadiy Belonosov. (#13361)
Fix the check in mne.make_forward_solution() that all MEG sensors are outside a spherical BEM model, by Marijn van Vliet (#13371)
Fix bug with mne.grand_average() not working with mne.time_frequency.Spectrum objects, by Thomas Binns. (#13375)
Ensure auto-computed plot scalings are always non-zero, by Daniel McCloy. (#13376)
Fix plot_evoked_joint() docstring to correctly document exclude parameter default as 'bads' instead of None, by new contributor Tharupahan Jayawardana. (#13391)
Make decoding classes sklearn-compliant, by Gennadiy Belonosov. (#13393)
Fix loading problems caused by attempting to iterate floats in read_epochs_eeglab() for specific EEGLab data, by new contributor Emrecan Çelik. (#13395)
Fix bug with mne.make_forward_solution() where sources were not checked to make sure they’re inside the inner skull for spherical BEMs, by Eric Larson. (#13407)
Preserve event-to-epoch mapping when exporting EEGLAB .set files by Scott Huberty (#13428)
Fix and update osf.io links to new format, by new contributor Johannes Herforth. (#13440)

API changes by deprecation#

Add on_few_samples parameter to mne.compute_covariance() and mne.compute_raw_covariance() for controlling behavior when there are fewer samples than channels, which can lead to inaccurate covariance estimates, by new contributor Emmanuel Ferdman. (#13350)
The default for mne.make_field_map() will change to "auto" in MNE-Python 1.12 (from (0., 0., 0.04)), changes by new contributor Paul Anders. (#13398)
Add encoding parameter to mne.io.read_raw_nihon() for better handling of annotation decoding, by Tom Ma. (#13458)

New features#

Support for preloading=False when reading .set files, by Bruno Aristimunha. (#13096)
Implement GEDTransformer superclass that generalizes mne.decoding.CSP, mne.decoding.SPoC, mne.decoding.XdawnTransformer, mne.decoding.SSD and fix related bugs and inconsistencies, by Gennadiy Belonosov. (#13259)
Implement mne.decoding.SpatialFilter class returned by mne.decoding.get_spatial_filter_from_estimator() for visualisation of filters and patterns for mne.decoding.LinearModel and additionally eigenvalues for GED-based transformers such as mne.decoding.XdawnTransformer, mne.decoding.CSP, by Gennadiy Belonosov. (#13332)
Add more options for the sphere parameter of mne.viz.plot_sensors(), by Marijn van Vliet (#13400)
Add support for BDF export in mne.export.export_raw(), by Clemens Brunner (#13435)
Improve precision of fiducial clicking in mne coreg, by Eric Larson. (#13445)
Add support for Nihon Kohden EEG-1200A V01.00, by Eric Larson. (#13448)

Other changes#

Changed “enhancement” to “new feature” in the contributing guide as enhancement is not a recognized change type, by Shristi Baral (#13373)
Add a SPEC0-like policy in which minimum-supported versions for select dependencies are set to the latest minor release that was available 2 years prior, by Thomas Binns (#13451)
