Releasing ShopifyAPI

1. Check the Semantic Versioning page for info on how to version the new release: http://semver.org

2. Update the version of ShopifyAPI in lib/shopify_api/version.rb

3. Run `bundle`

4. Add a CHANGELOG entry for the new release

5. Commit the changes with a commit message like "Packaging for release X.Y.Z"

6. Tag the release with the version (Leave REV blank for HEAD or provide a SHA)

$ git tag vX.Y.Z REV

7. Push out the changes

$ git push

8. Push out the tags

$ git push --tags

9. Publish the gem using Shipit

10. Consider if the dependency in Shopify/shopify needs updated. It's used only by the tests so is a low risk change.

Also consider Shopify/shopify_app whose gemspec depends on this.

We don't need to do this for every release, but we should try to keep them relatively up to date.
