After the release of BRIDG 5.3.1, BRIDG will cease publishing a comprehensive mapping spreadsheet containing the mappings from all previous harmonizations. This file, which contains many very old harmonizations, is getting quite large and has made the release package difficult for some to download. Therefore BRIDG is archiving the current comprehensive mapping spreadsheet and will commence with a new mapping spreadsheet which will include all new harmonizations unless or until it becomes unwieldy and is also archived, at which time a new file will be started again.
