| 218424 | 2019-09-18 | cif/7/20/04/ Replaced the incorrect bibliographical reference to the original publication with a proper one in entries 7200490-7200494. |

| 206958 | 2018-03-15 | Fixing many Z values and formulae detected when treating files that initially displayed Z' < 1 |
7200492.cif |
| 180335 | 2016-03-26 | cif/7/20/ (antanas@kurmis) Replacing _[local]_cod_* tags with their equivalents from the COD CIF dictionary in multiple entries in subrange 7/20/04. |

| 35909 | 2012-02-26 | cif/7/: reorganising range 7 into a prefix-directory tree. | 7200492.cif |
| 5312 | 2011-01-03 | cif/ Adding files, updated with the 'cif_fix_enum' program and the cif_core.dic dictionary. The enumerator values were fixed, mostly incorrect case, but also some values that had extra underscores, dashes or spaces. Unfortunately, 22 had non-ASCII characters with the 8-th bit set, and these got incorrectly interpreted as latin1 characters and converted to their UTF8 equivalents by Perl. To fix the structures, however, they need to be redeposited from the original files with the new CIFParser/cif_filter version. |
7200492.cif |
| 1167 | 2010-05-13 | cif/ Adding data from the rest of 2009 RSC journals, Inorg-Chem-2008 and Chem-Comm-2010_18-19. |
