The Stanford NetDB team releases new versions of NetDB once or twice a year. NetDB versions are identified by a three-part version number. The NetDB open source releases include a release number as well (this allows us to make multiple releases of the same version - to address build issues discovered by others for example). New versions include scripts to upgrade the database from the previous version.
