In order to publish the new release to PrestaShop addons, you need to create a pull-request to the PrestaShop/nostotagging repository, which this repository is a fork of. Always create the pull-request from Nosto:master => PrestaShop:master. PrestaShop will then review the release and publish it within a day or two. Remember to give a good explanation of the things that have changed in the pull-request comment field. It will help PrestaShop when reviewing.
