# Nomad Go Version

Nomad is intended to be built with a specific version of the Go toolchain for
each release. Generally, each Y release of Nomad (where 0.9.5 means X=0, Y=9,
Z=5) will update to the latest version of the Go toolchain available at the
time.

Nomad Z releases update to the latest Go Z release but do *not* change Go's Y
version.
