Here are some things you can do to keep up with the news about the Confluence 4.0 editor:

• Watch the Confluence 4.0 Editor FAQ page, and any other pages you like, if you would like Confluence to send you an email when we update the page.
  To watch a page, sign up for a username on this documentation wiki if you do not already have one, then open the 'Tools' menu on the page and click 'Watch'.
• Sign up to the Confluence User Task Force.

  The purpose of this user task force is to give you the opportunity to provide a more detailed level of feedback on Confluence as a product. This will help us learn more about our market and better meet your needs. Members of the task force would be asked to participate in such things as: General surveys on Confluence use cases, features and ideas. Feedback on early releases of the product. Usability and user experience testing. How often would you be asked to participate? As a general rule we won’t be asking you to participate any more than once a month.

  We will notify all members of the Confluence User Task Force once the new editor is available for feedback. You can sign up here.
