-of `client-go`, or *ii)* makes `client-go` incompatible with otherwise supported
-versions of Kubernetes clusters.

-Kubernetes version numbers.

-`(x+1).0.0-alpha` (depending on whether it has accumulated a breaking change or
-not), where `x` and `y` are the current major and minor versions.
+The HEAD of the master branch in client-go will track the HEAD of the master

 #### Compatibility: your code <-> client-go
 
-`client-go` follows [semver](http://semver.org/), so until the major version of
-client-go gets increased, your code will compile and will continue to work with
-explicitly supported versions of Kubernetes clusters. You must use a dependency

-benefit, as HEAD follows the upstream Kubernetes repo.
+The `v0.x.y` tags indicate that go APIs may change in incompatible ways in
