Print out repository releases with go-github

I am very new to Go and am having issues printing out all releases for a given repo using the go-github api.

I am adapting my code from the example in the project here.

This is the code I have so far.

package main

import (
  "fmt"
  "github.com/google/go-github/github"
  "golang.org/x/oauth2"
)

func main() {

// authentication
ts := oauth2.StaticTokenSource(&oauth2.Token{AccessToken: "XXX"})
tc := oauth2.NewClient(oauth2.NoContext, ts)

client := github.NewClient(tc)

// list all releases for single repo
fmt.Println("Releases for repo")
opt := &github.ListOptions{Page: 2, PerPage: 10}
releases, _, err := client.Repositories.ListReleases("hashicorp", "terraform", opt)

if err != nil {
    fmt.Printf("error: %v\n", err)
} else {
    for _, release := range releases {
        fmt.Printf("%v\n", release)
    }
}

This works and runs okay (no errors at least), but when I run it, the code doesn't return anything. I have a feeling I am missing something simple but am stuck scratching my head.

From the GitHub documentation on the list releases API:

> This returns a list of releases, which does not include regular Git tags that have not been associated with a release. To get a list of Git tags, use the Repository Tags API.

Since the repository you specified contains only tags and not releases, nothing is returned.

Changing ListReleases to ListTags yields output similar to the following:

Releases for repo
