What's New change to use notifications?

I’m exploring the What’s New to notify of new features / changes in our instance upon update (see "What's new" feature feedback request - #10 by watery) and since we move from LTS to LTS, this is going to show one message per year.

Our instance is used inside our company, by few users.

For me:

  1. it’s enough to have an hint inside the Wiki (no need for emails or anything else)
  2. an icon similar to the bell for page edits would be good, but it must be a separate icon, so notifications about news aren’t diluted between notifications of page changes
