Soon, you'll be able to release all your extensions at the same time, directly from Shopify CLI. New app-level extension versioning will help you to keep better track of your app's iterations, and allow you to easily revert to previous versions, if needed. You’ll also be able to preview Functions using the dev command, and delete any extension.
This functionality will be included in a future release of Shopify CLI. You'll be able to opt in for each app that you develop.
