What's New change to use notifications?

and since we move from LTS to LTS, this is going to show one message per year.

The notification would be about “what’ new” news, so anytime there’s a new news, a notification would be sent.

• it’s enough to have an hint inside the Wiki (no need for emails or anything else)
• 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

The notifications system of XWiki is not just for wiki page changes. It’s generic and for any type of change. I think what you’re asking for is the ability to filter notifications. This is planned as part of the notification inbox feature, see Notification Inbox.
