We constantly release updates for our products. Once a new version is available, you can find it listed in your Dashboard → Updates page.
Moreover, you can also update the theme by going to Appearance → Themes too. When a new version is up and kicking, the theme will have a badge at the top saying that there’s a New version available. As you can see, it is easy to keep track with the evolution of the theme, and benefit of bug fixes and new features.
