+### The admin example deletes a group's grants and members in one Keto transaction

+A Keto failure while deleting a group now leaves the group as it was, with its grants and members,
+and answers with the error page. It used to leave some grants gone and the members still listed.

+### The core dashboard view is `dashboard`, not `index`
+
+`views/index.ejs` is now `views/dashboard.ejs`, named for the `/dashboard` page it renders. A plugin
+view that does `include("index")` must include `dashboard` instead.
