Showing Announcements to Public Users
Announcements can be made public, in which case non-authenticated users can see them.
This can be particularly useful for Jira Cloud instances that have public projects of some kind.
To create a public announcement simply follows the steps for creating an announcement, and select the "Public" announcement type.
note:
Public announcements are only shown to anonymous (unauthenticated users). Logged in Jira users will not see a public announcement.
