Gonum supports and tests on the [two most recent Go releases](https://github.com/gonum/gonum/blob/master/.travis.yml#L6-L10) on Linux, macOS and Windows.
+## Release schedule
+
+The Gonum modules are released on a six-month release schedule, aligned with the Go releases.
+_i.e.:_ when `Go-1.x` is released, `Gonum-v0.n.0` is released around the same time.
+Six months after, `Go-1.x+1` is released, and `Gonum-v0.n+1.0` as well.
+
+The release schedule, based on the current Go release schedule is thus:
+
+- `Gonum-v0.n.0`: February
+- `Gonum-v0.n+1.0`: August
## Build tags
-The gonum packages use a variety of build tags to set non-standard build conditions.
-Building gonum applications will work without knowing how to use these tags, but they can be used during testing and to control the use of assembly and CGO code.
