201974 (current)	2017-10-13	cif/2/ Marking COD entries in range 2/21 that are known to be related to ChemSpider entries using the _cod_related_entry data loop.	2217881.cif 2217881.hkl
181098	2016-04-03	hkl/2/21/ (antanas@echidna) Replacing _[local]_cod_* tags with their equivalents from the COD CIF dictionary in multiple entries in subrange 2/21/78.	2217881.cif 2217881.hkl
176787	2016-02-20	cif/2/ (antanas@kurmis) Replacing _[local]_cod_* tags with their equivalents from the COD CIF dictionary in multiple entries in subrange 2/21.	2217881.cif 2217881.hkl
91933	2013-12-28	cif/ (saulius@koala.ibt.lt) Adding DOIs that could be assigned unambiguously to the range 2x CIFs.	2217881.cif 2217881.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.	2217881.cif 2217881.hkl
32112	2012-02-03	cif/: committing an update of 45+ thous files, with information appended from the originals.	2217881.cif 2217881.hkl
26848	2011-09-28	cif/2/, hkl/2/, html/ Reorganising CIFs of the range 2* into the "prefix-directory" tree.	2217881.cif 2217881.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).	2217881.cif 2217881.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.	2217881.cif 2217881.hkl
966	2010-01-30	cif/ Adding _cod_database_code tags to all COD entries. Adding tag description to the cif_cod.dic dictionary so that COD entries can be validated.	2217881.cif 2217881.hkl
903	2009-11-23	cif/ Setting svn:keywords property on those CIFs that did not have them.	2217881.cif 2217881.hkl
697	2009-05-05	Adding 1667 more Fobs files, ones that have cell constans differenig not more than 0.1% from the cell constants in the coordinate file. The symmetry operators must also match in both files.	2217881.cif 2217881.hkl
450	2008-10-01	Adding changes after the recent Acta-Cryst-E-2008-03-08/ (mostly, inserted the _journal_coeditor_code tags).	2217881.cif
446	2008-09-30	Adding new CIF files from the Acta-Cryst-E-2008-03-08/ deposition.	2217881.cif
