In the pre1.0 / post1.0 world of Go, we had some confusion with our stathatgo and treap packages. We had different repositories for the version that worked with the weekly releases before go1.0 and the release version (we should have used branches…).

We cleaned it up and there is just one repository for each of these packages. If you were using stathatgo1 or treap1 then you should change your import statements to use github.com/stathat/stathatgo and github.com/stathat/treap.
