If you are for the first time on this site please read the introduction.
Every newly released version of the genome database is a new snapshot of the genome project, that would have hopefully more joins done, new sequence data added, rearrangements resolved, etc. While the number of contigs changes, the assembly software produces new contig numbers all the time. Hence the necessity of updating the DNA and BLAST databases for every version.
Finally it's completely finished and annotated.
