# v0.1.20

> Temporal annotation format fix

<Update label="2026-07-16" description="v0.1.20: temporal annotation format fix">
  ## Fixed: temporal annotation format on `PATCH /api/v1/tkgs/{tkgId}/graph/nodes/{nodeId}/annotation`

  The request body now uses `{ timestamp: "2026-09-30", precision: "quarter" }` (an ISO 8601 date) instead of the previous loose `{ when: "2026 Q3", precision: "quarter" }` string. This aligns with the annotation format already used elsewhere on the platform.

  The endpoint now also merges into any existing annotation data instead of overwriting it, so other fields (like source provenance) are preserved.

  `capture_temporal` actions from `POST /api/v1/chat` now return `timestamp` (ISO 8601) instead of `when`, so you can pass it straight through to this endpoint.
