From now on the validation phase of your new release takes place through two singles buttons in the screen of your release loaded: "Validate it" and "Distribute it".
1) "Validate it": check if the release is in place and ready-to-go. In addition, if it's needed, from here you can active the Promopool and/or Antipiracy services on the release.
2) "Distribute it": distribute the release.
