WooCommerce Needs Update

Just purchased Highend and am setting it up. Received this message. I assumed that updates would always be done on these themes as a part of using them?

” Your theme (Highend) contains outdated copies of some WooCommerce template files. These files may need updating to ensure they are compatible with the current version of WooCommerce. Suggestions to fix this:

Update your theme to the latest version. If no update is available contact your theme author asking about compatibility with the current WooCommerce version.”
