https://golang.org/doc/devel/release.html#go1.7.minor > go1.7.5 (released 2017/01/26) includes fixes to the compiler, runtime, and the `crypto/x509` and `time` packages. See the [Go 1.7.5 milestone](https://github.com/golang/go/issues?q=milestone%3AGo1.7.5) on our issue tracker for details. Patch is forthcoming, once I test it. There is now a Go 1.8 too, but I figured you would want a 1.7.5 patch first.
