 As of [June 19th, 2015](https://groups.google.com/d/msg/golang-dev/74zjMON9glU/EOKSoaL5p8wJ), the Go toolchain included an experimental vendoring flag, `GO15VENDOREXPERIMENT`. This was part of the Go 1.5 release and represented the Go team's recommended approach to vendoring dependencies. You can read more about how this environment variable worked in the [Go 1.5 documentation](https://golang.org/cmd/go/#hdr-Vendor_Directories) and the [original design document](https://docs.google.com/document/d/1Bz5-UB7g2uPBdOx-rw5t9MxJwkfpx90cqG9AFL0JAYo/view). For a more detailed explanation, check out [this post](https://medium.com/@freeformz/go-1-5-s-vendor-experiment-fd3e830f52c3) by [@freeformz](https://twitter.com/freeformz) or [this short explainer](http://engineeredweb.com/blog/2015/go-1.5-vendor-handling/) from Engineered Web.
 
-The Go 1.6 release made this behaviour the default, so you no longer need to have `GO15VENDOREXPERIMENT` set. Go 1.7 maked this a standard feature and removed support for the flag.
