In February, 2019, the [[wwPDB]] announced that new depositions must be in the mmCIF format beginning July 1, 2019<ref name="endOfPDBFormat">[https://lists.sdsc.edu/pipermail/pdb-l/2019-February/006209.html Mandatory PDBx/mmCIF format files submission for MX depositions]: posted on the PDB email list Feb 20, 2019 by Jasmine Young, Biocuration Team Lead, RCSB PDB. The wwPDb website also posted [http://www.wwpdb.org/news/news?year=2019#5c6ad3c5ea7d0653b99c8766 this document].</ref>. The PDB sometimes refers to the mmCIF format as "PDBx", which should not be confused with the original legacy PDB format.
