| 301812 (current) | 2025-08-19 | Add cross-references to PubChem compounds in COD range 4/02/ Each referenced PubChem compound corresponds to the full crystal structure. | 4025178.cif | 
| 178430 | 2016-03-21 | cif/4/02/ (antanas@kurmis) Replacing _[local]_cod_* tags with their equivalents from the COD CIF dictionary in multiple entries in subrange 4/02/51. | 4025178.cif | 
| 130086 | 2015-01-23 | cod/ (robertas@burundukas) The 'cif_fix_values' program was applied to CIFs that have generated the validation messages containing tag '_exptl_crystal_density_meas'. 16946 CIFs had a values that were perceived as 'not measured' and they were changed to '?'. The total of 17089 CIFs was changed. Those that were not corrected by 'cif_fix_values' were reformatted by the parser (e.g. a doi tag was moved to another place). The processing command was: mysql -u cod_reader -h www.crystallography.net cod -e \ 'select distinct codid from validation \ where message like \ "%tag%_exptl_crystal_density_meas'\''%"' -NB \ | xargs -i sh -c 'cif_fix_values {} \ | cif_filter --add-cif-header {} \ | sponge {}' | 4025178.cif | 
| 91935 | 2013-12-29 | cod/ (saulius@koala.ibt.lt) Adding DOIs that could be assigned unambiguously to the rest of COD CIFs. | 4025178.cif | 
| 34330 | 2012-02-24 | cif/4/ Reorganising CIF range 4 into a prefix tree. | 4025178.cif | 
| 17004 | 2011-03-31 | cif/ Commiting CIFs, that were updated with the 'cif_fix_values' script, using options '--fix-misspelled replacement_values.lst', '--fix-temperature' and '--fix-enums' with built-in table of enum values. The following cmd was used: > (set -x; find ? -name \*.cif | sort | xargs -i sh -c 'if !( > cif_fix_values --fix-misspelled ~/../inputs/replacament_values.lst {} | > cif_filter --add-cif-header {} | > sponge {} ) 2>&1 | grep NOTE; then svn revert {}; > fi' ) & | 4025178.cif |
