179124 (current)	2016-03-23	cif/4/30/ (antanas@kurmis) Replacing _[local]_cod_* tags with their equivalents from the COD CIF dictionary in multiple entries in subrange 4/30/86.	4308687.cif
120081	2014-07-12	Adding DOIs to range 4/30 structures.	4308687.cif
34330	2012-02-24	cif/4/ Reorganising CIF range 4 into a prefix tree.	4308687.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.	4308687.cif
1526	2010-09-26	cif/4/ Adding new CIFs from Inorg. Chem. 2005 deposited via Web deposition site to the COD test database (and transferede to the main COD database after renaming).	4308687.cif
