NetBSD makes new major releases approximately every 2-3 years, with point releases occurring every 6-12 months for the latest and prior major release. One month after a new major release, support typically ends for the NetBSD major release 2 versions prior. NetBSD also releases daily snapshots of the development source code tree as NetBSD-current.
