The banner now points to the current release's announcement page, which is really
the 'dashboard' for a new release, and has all the right links for the user.
Events are used for special announcements. There are stickers and banners that can be
displayed to the user. These can be used to announce an imminent release with a
sticker and countdown clock, or can be used to invite users to a future
conference, or can be used to announce that a new release is available for download.
See the authoring guide for instructions on how to use these announcements.
