## Deleting a label in use is refused instead of stranding it

labels, fix, release

**v1.17.0** `DELETE /Labels/{id}` now returns a `409` while any record or Mini still carries the label, telling you how
many do. Records and Minis reference a label by name, so deleting one in use used to leave that name on them while
destroying the access grants attached to it. Clear the label off them first. A call that succeeds still returns `204`
and the label disappears at once, but its grants are torn down in the background, so creating a label with the same name
straight after can be refused until that finishes.

## Identify a Mini by NHS number

minis, schema

**v1.16.0** Handles `nhs` as an identity `kind` so the NHS number a UK care provider knows a client by is stored and
searchable alongside the Australian schemes. It reads back on the Mini like any other identity.
