WormBase has been updated to the WS140 release of the database. New
features include the introduction of a unified Variation class, which
consolidates all information on alleles and polymorphisms into a
single class. To support this class, the Locus and Allele/Variation displays have
been overhauled. WS140 will be a “frozen” release of the data and
software, permanently available at ws140.wormbase.org in three weeks.
