Hey @Agustin_Reynaud,
So whenever you publish a release, it becomes the live version in user mode, and any changes that you make to your app after that will not be visible to the user until you publish another release.
Let's say yesterday you published all your work, and at the end of today, you will create a draft release for the work done. If tomorrow you decide that what you did today was not worth it, you can revert your working version to the last or any other release you have pushed.
There's a similar thread here, you may find it useful:
