Go 1.12 was released on 2/25/2019: https://blog.golang.org/go1.12 Go 1.12.1 was released on 3/14/2019: https://golang.org/doc/devel/release.html#go1.12.minor Additional notes on how Go modules will evolve in 2019 are here: https://blog.golang.org/modules2019 In Go 1.12, module support remains the same as in Go 1.11. GOPATH is scheduled for deprecation in 1.13, however. The Buildroot Go package infrastructure should therefore aim to migrate to a new, currently undefined, Go module friendly compilation approach before Go 1.13 is released.
