SGD has instituted a genome versioning system. There are a total of 95 individual updated versions of the 16 nuclear chromosomes between the original release and this latest major update (R64.1.1).
a
The mitochondrial chromosome was not part of the original genome project and was determined separately (Foury et al. 1998).
