This summer we made it easier to release your software. Today, you can fully automate those releases via the
Releases API Preview. :sparkles::zap::rocket:

You can even upload binaries in a single step:

curl -H "Authorization: token <yours>" 
     -H "Accept: application/vnd.github.manifold-preview" 
     -H "Content-Type: application/zip" 
     --data-binary @build/mac/package.zip 
     "https://uploads.github.com/repos/hubot/singularity/releases/123/assets?name=1.0.0-mac.zip"

Check out the full API docs for details, and go build something!
