# `PhoenixKit.Migrations.Postgres.V121`
[🔗](https://github.com/BeamLabEU/phoenix_kit/blob/v1.7.165/lib/phoenix_kit/migrations/postgres/v121.ex#L1)

V121: Widen `phoenix_kit_annotations_kind_check` for the new
`"line"` kind.

Etcher gains a simple two-endpoint line annotation alongside
`dimension` — same geometry (`{a: [x, y], b: [x, y]}`) but no
arrowheads and no inline numeric label. Title + comment ride the
same composer flow as `rectangle` / `circle` / `polygon`.

Idempotent: each `ADD CONSTRAINT` is preceded by `DROP CONSTRAINT
IF EXISTS` on the same prefixed table.

# `down`

# `up`
