The new SCRATCH 8.2 is currently available in Pre-Release on the Assimilate support site.
This goes along with a redesign of the SCRATCH Web page and a direct access to it.
SCRATCH Web contains a "Public" page (or Construct) where you can find all the latest tutorials in several languages.
SCRATCH Web is also the place where existing users can request a "Publish" account and upload their Constructs to their own "private" zone before inviting their clients or collaborators to play, review and annote their work in a secure environment.
These notes can be then synced back with the original SCRATCH project.
Remember: Anyone can have access to SCRATCH Web. Users and visitors. Just need to register.
