• mne.set_eeg_reference() and the related methods (e.g., mne.io.Raw.set_eeg_reference()) have a new argument projection, which if set to False directly applies an average reference instead of adding an SSP projector, by Clemens Brunner

• Deprecate plot_trans in favor of mne.viz.plot_alignment() and add bem parameter for plotting conductor model by Jaakko Leppakangas

• mne.beamformer.tf_lcmv now has a raw parameter to accommodate epochs objects that already have data loaded with preload=True, with mne.Epochs.load_data(), or that are read from disk, by Eric Larson

• mne.time_frequency.psd_welch and mne.time_frequency.psd_array_welch() now use a Hamming window (instead of a Hann window) by Clemens Brunner

• Deprecate force_fixed and surf_ori in mne.read_forward_solution() by Daniel Strohmeier

• mne.convert_forward_solution() has a new argument use_cps, which controls whether information on cortical patch statistics is applied while generating surface-oriented forward solutions with free and fixed orientation by Daniel Strohmeier

• mne.write_forward_solution() writes a forward solution as a forward solution with free orientation in X/Y/Z RAS coordinates if it is derived from a forward solution with free orientation and as a forward solution with fixed orientation in surface-based local coordinates otherwise by Daniel Strohmeier
