Expose MRI defacing function to public API as mne_bids.deface_mri() by Erica Peterson (#1544)
Add an extra_fields parameter to make_dataset_description() to write additional top-level keys to dataset_description.json, by Bruno Aristimunha (#1674)
Add mne_bids.open_lock(), the cross-process file lock mne-bids uses for shared files such as participants.tsv, so downstream writers can share it, by Bruno Aristimunha (#1675)

Sidecar files are now written to a temporary file and moved into place, so reading them no longer takes a file lock, and a sidecar whose content would not change is no longer rewritten, by Hamza Abdelhedi (#1680)

Fix readers seeing a partially written sidecar while another process was rewriting it, by Hamza Abdelhedi (#1680)
Fix parallel mne_bids.write_raw_bids() calls for BTi/4D data overwriting each other’s .bidsignore changes, by Hamza Abdelhedi (#1680)
Fix find_matching_paths() omitting files with a tracksys entity and returning no matches when tracking_systems is specified, by Shubham Padkonde.
Allow acquisition="calibration" or "crosstalk" together with a task in BIDSPath when datatype is not "meg", since these labels are reserved only for MEG fine-calibration and crosstalk files, by Bruno Aristimunha (#1673)

mne_bids.read_raw_bids() now parses participants.tsv once per version of the file instead of on every call, so reading every recording of a large dataset no longer gets slower as the number of subjects grows, by Hamza Abdelhedi (#1681)
Dropping rows from a TSV table no longer deep-copies the table first, by Hamza Abdelhedi (#1681)
Sped up mne_bids.read_raw_bids() and mne_bids.write_raw_bids() on network filesystems by taking fewer file locks, by Hamza Abdelhedi (#1680)
