   Building the human genome
While the draft sequence of the human genome was officially launched early in 2001, data are produced on a continuous basis. This allows the reference human genome sequence to be further refined and completed as an ongoing process. At NCBI, new versions of the assembled genomic sequence are released every few weeks. The current version is listed as a build number on the Genome View page. Each build has an accompanying set of statistics and release notes.
