mne_bids.write_raw_bids() has a new parameter electrodes_tsv_task which allows adding the task entity to the electrodes.tsv filepath, by Alex Lopez Marquez (#1424)
Extended the configuration to recognise motion as a valid BIDS datatype by Julius Welzel (#1430)
Better control of verbosity in several functions, by Bruno Aristimunha (#1449)
Added parallel reading and writing in all the open operations using _open_lock mechanism from mne, creating a small wrapper to manage the locks by Bruno Aristimunha (#1451)
mne_bids.BIDSPath.match() now short-circuits root directory scans when subject, session, or datatype entities are known, reducing lookup time on large datasets, by Bruno Aristimunha and Maximilien Chaumon (#1450)

tracksys accepted as argument in mne_bids.BIDSPath() by Julius Welzel (#1430)
mne_bids.read_raw_bids() has a new parameter on_ch_mismatch that controls behaviour when there is a mismatch between channel names in channels.tsv and the raw data; accepted values are 'raise' (default), 'reorder', and 'rename', by Kalle Mäkelä.
Column names read from .tsv are now converted from numpy.str_ class to built-in str class, by Daniel McCloy (#1475).

MNE-BIDS now requires Python 3.11 or higher.
Including filelock as a dependency to handle atomic file writing and parallel processing support by Bruno Aristimunha (#1451)
None yet

Fixed a bug that modified the name and help message of some of the available commands, by Alex Lopez Marquez (#1441)
Updated MEG/iEEG writers to satisfy the stricter checks in the latest BIDS validator releases: BTi/4D run folders now retain their .pdf suffix (falling back to the legacy naming when an older validator is detected), KIT marker files encode the run via the acq entity instead of run, datasets lacking iEEG montages receive placeholder electrodes.tsv/coordsystem.json files, and the AssociatedEmptyRoom entry stores dataset-relative paths by Bruno Aristimunha (#1449)
Made the lock helpers skip reference counting when the optional filelock dependency is missing, preventing spurious AttributeError crashes during reads, by Bruno Aristimunha (#1469)
Fixed a bug in mne_bids.read_raw_bids() that caused it to fail when reading BIDS datasets where the acquisition time was specified in local time rather than UTC only in Windows, by Bruno Aristimunha (#1452)
Fixed bug in write_raw_bids() where incorrect unit was sometimes written into channels.tsv file when converting data to BrainVision, EDF, or EEGLAB formats, by Daniel McCloy (#1475)
Converting data to EDF format while also anonymizing it will now yield valid EDF files (with startdate set to 1985-01-01 00:00:00); the BIDS-compliant anonymized date will still be stored in scans.tsv file and restored to the in-memory Raw object when read using read_raw_bids(), by Daniel McCloy (#1479)

Made mne_bids.copyfiles.copyfile_brainvision() output more meaningful error messages when encountering problematic files, by Stefan Appelhoff (#1444)
Raised the minimum edfio requirement to 0.4.10, eeglabio to 0.1.0 by Bruno Aristimunha (#1449)
Relaxed EDF padding warnings in the test suite to accommodate upstream changes by Bruno Aristimunha (#1449)
Adapt to upstream switch to new reader package for Neuroscan-Curry-format files, by Daniel McCloy (#1475)
