It now runs a permission check before it reads or writes anything. If the check returns an error, the edit stops there and you see that error. The notebook is left untouched.\n\n**Why**\n\nA notebook edit that fails the permission check is now refused before any work on the file begins.\n\n- Area: Permissions\n- Tier: You'll notice\n- Useful: 2\/5\n- Signal: 1\/5\n- Scope: individual\n- Heads-up: no"}
