+===============================================================================
+* Bug fix: iso_finish() left an invalid global pointer, which a subsequent 
+           call of iso_init() would try to dereference.
+* The sort weight of data files loaded from ISO image is now 2 exp 28 to 1
+  rather than 2 exp 31 - 1 to - 2 exp 31

 libisofs-1.3.0.tar.gz Fri May 17 2013
 ===============================================================================
 * Bug fix: GPT header CRC was computed from all 512 bytes rather than from 92.
