# Changelog

> Notable additions and changes to the Kua API.

Changes to the public `/v1` API. All updates are
[additive and backwards-compatible](/concepts/versioning); new endpoints, fields,
and event types can appear at any time.

<Update label="July 2026" description="Developer platform launch">
  **The Kua developer platform is live.**

  * **API keys** — issue, scope, and rotate keys from **Settings → API keys** in
    the dashboard. Keys support `employees:write` and `payroll:write`
    [scopes](/authentication#scopes), plus `*`.
  * **Public `/v1` endpoints** — payroll runs (list + create), employees (create),
    and the events timeline.
  * **Webhooks** — register endpoints, receive signed, retried, at-least-once event
    deliveries, and inspect delivery attempts. See
    [webhooks](/webhooks/overview).
  * **Test mode** — `kua_test_…` keys operate on isolated
    [sandbox data](/concepts/data-model#test-mode) that never moves real money and
    auto-purges after 14 days.
  * **Official SDKs** — [`@kua/node`](/sdks/node) and [`kua` for Python](/sdks/python).
  * **Docs** — this site, with a live [API reference](/api-reference) playground.
