301805 (current)	2025-08-19	Add cross-references to PubChem compounds in COD range 2/22 Each referenced PubChem compound corresponds to the full crystal structure.	2224841.cif 2224841.hkl
181169	2016-04-03	hkl/2/22/ (antanas@echidna) Replacing _[local]_cod_* tags with their equivalents from the COD CIF dictionary in multiple entries in subrange 2/22/48.	2224841.cif 2224841.hkl
176789	2016-02-20	cif/2/ (antanas@kurmis) Replacing _[local]_cod_* tags with their equivalents from the COD CIF dictionary in multiple entries in subrange 2/22.	2224841.cif 2224841.hkl
91933	2013-12-28	cif/ (saulius@koala.ibt.lt) Adding DOIs that could be assigned unambiguously to the range 2x CIFs.	2224841.cif 2224841.hkl
88064	2013-08-29	Adding _cod_database_fobs_code data item to all COD CIFs that have Fobs deposited and did not have this data item yet.	2224841.cif 2224841.hkl
32112	2012-02-03	cif/: committing an update of 45+ thous files, with information appended from the originals.	2224841.cif 2224841.hkl
26848	2011-09-28	cif/2/, hkl/2/, html/ Reorganising CIFs of the range 2* into the "prefix-directory" tree.	2224841.cif 2224841.hkl
26029	2011-09-17	cif/2/ Reverting changes of revision 25271: ( cd cif/2/; svn merge -r25271:25270 . ) The problem was that the reprocessed files from IUCr, although were more complete, "resurrected" data errors that were corrected in the previous recisions. The additional data that have been extracted during the reprocessing will have to be merged without overwriting the existing values in COD files, except some explicit and controlled cases (such as publication titles and chemical names).	2224841.cif 2224841.hkl
25271	2011-09-10	cif/2/ Adding reporocessed IUCr CIFs for the years 1980-2010. The CIFs now contain more complete bibliography, substance names, correctly unfolded text fields (using the CIF line unfolding protocol), explicitely set cell angles, and _cod_data_source_block fields.	2224841.cif 2224841.hkl
5310	2011-01-02	cif/ Running cif_fix_enum with the core CIF dictionary on COD ranges 2, 8 and 9. Range 9 remained unchanged, and in ranges 2 and 8 there were 17309 modified files, most changes were fixes enumerator case.	2224841.cif 2224841.hkl
1024	2010-03-05	hkl/2/ Depositing Fobs data for the coordinates from the IUCr 2010 February publications' deposition.	2224841.cif 2224841.hkl
1021	2010-03-05	cif/2/ Adding CIFs after IUCr 2010 February data processing.	2224841.cif
