283866 (current)	2023-05-18	cif/9/ (saulius@tasmanijos-velnias) Commiting those range 9 files that, after automatic atom type determination and manual atom type and hydrogen count fixes, have declared and calculated formulae matching in all atom counts but hydrogen.	9013918.cif
282068	2023-03-26	cod/ (saulius@tasmanijos-velnias) Adding the '_cod_related_entry_...' loop to those COD AMCSD entries that lacked it, and adding the related AMCSD database ID to this loop.	9013918.cif
282053	2023-03-24	cod/ (saulius@tasmanijos-velnias) Updating the existing COD records from the recent AMCSD downloads: - Adding AMCSD IDs to those COD records that exacly matched the AMCSD structures (comparing unit cells, space groups, coordinates and measurement conditions) but did not yet have the AMCSD ID; - Adding new mineral names, compound sources, measurement conditions (when those were missing) and other informations from the AMCSD CIFs.	9013918.cif
