## What's new

- **API writes name each field that failed.** When a value breaks the screen's own rules, a write
  is refused with `422 validation_failed`, and the response's `fields` lists every failing field by
  the name you sent it under. See
  [Write API: registrations, applications, notes, tags and assignments](/integrations/api-c02-write-api-part-one-registrations-applications-no).

## Fixed

- **The Sharing list shows nothing to someone with no access to Assessments.** An Administrator with
  `No Access` to Assessments on every round could see the Organisation's shares listed, though
  opening one was already refused. The list is now empty for them. Anyone who can reach Assessments
  on at least one round sees what they did before. See
  [Assessment sharing](/administrator/assessments/assessment-sharing).
