v2.140.131 May 2026

Prosperity Index now returns a valid ISO 8601 computedAt timestamp

The computedAt field on the Prosperity Index endpoint now returns a strict ISO 8601 UTC timestamp, so it passes datetime validation and deserialises cleanly in the SDKs.

Fixed

The computedAt field returned by GET /v1/prosperity/{geographicCodes} is now a strict ISO 8601 / RFC 3339 UTC string with millisecond precision and a trailing Z (e.g. 2026-05-31T07:30:03.988Z).
Generated SDKs deserialise the value directly, with no client-side date coercion.
