@everyone

You can now mention @everyone in a comment which will send a notification to each team member who has access to the team library the note is in. The notification, like all mentions, will be sent via each member's preferred notification channels, including in-app, mobile, email, and Slack.

This is an easy way to notify all members when a new note has been created that they shouldn't miss. Or when you are specifically looking for input from the entire team.
