 ## Dep
 
 `dep` is a dependency management tool for Go. It requires Go 1.9 or newer to compile.
 
-`dep` was the "official experiment." The Go toolchain, as of 1.11, has
-(experimentally) adopted an approach that sharply diverges from `dep`. As a
-result, we are continuing development of `dep`, but gearing work primarily
-towards the development of an alternative prototype for versioning behavior in
-the toolchain.
