Notes:
- Projects, the all-new projects experience, is now available. For more information about Projects, see "About Projects" and for information about migrating your classic project, see "Migrating from projects (classic)."
- You can only create a new classic project board for an organization or user that already has at least one classic project board. You cannot create new classic projects for repositories. If you're unable to create a classic project board, create a project instead.
