How Long Is a Go Version Supported? About One Year
Go's support policy is short and simple; here is what it means in practice.
Aditya Challa1 min read
Summary
Each major Go release is supported until there are two newer major releases, according to the official Go release policy. Because Go ships a new major version about every six months, that works out to roughly one year of support (an estimate based on the cadence, not a fixed date).
The official policy
Supported releases get minor point releases for critical problems, including security fixes. Once two newer majors exist, the old one gets no more fixes.
Release cadence
Go has historically released new majors around February and August each year. Treat future dates as estimates until the Go team announces them.
What it means for you
Stay within the two newest Go versions. The go directive and toolchain line in go.mod make it easy to test and move to a newer toolchain.
