7.1.1

Feature

• Addons can optionally include a razzle.extend.js file in their root. This
  module needs to follow the same rules as the razzle.config.js. They change
  the default Volto Razzle configuration, before it is passed to the Volto
  project. @tiberiuichim @sneridagh

Bugfix

• Managed hidden fields @giuliaghisini
• Fix bug in addon loading with namespaced packages @tiberiuichim
• Japanese translation updated @terapyon
