<Update label="June 2026" date="2026-06-06" tags={["Deprecation"]}>
  ### Legacy API paths move to /v1 — sunset 2026-07-11

  * Chat completions, sessions, webhook subscriptions, and outbound calls now have `/v1` paths. The new paths are live today and use the same Developer Key authentication.
  * The legacy paths under `/project/:projectId/integration/*` and `/project/:projectId/webhooks/*` are deprecated and **stop working on 2026-07-11**. Until then they keep working and return `Deprecation` / `Sunset` response headers.
  * Only the path changes — request and response bodies are unchanged. See the [migration guide](/en/migrations/2026-06-outbound-api-v1) for the full old → new path table.
</Update>

<Update label="May 2026" date="2026-05-01" tags={["New Feature"]}>
  ### Post Webhooks

  * Post-session webhook now supports four events — `session.ended`, `call.ended`, `session.finalized`, and `recording.ready` — selectable per agent.
  * `session.finalized` fires once every expected step (conversation end + call end, where applicable) has completed, and merges the data from earlier events into one body so receivers only need to handle one callback.
  * `recording.ready` (call sessions only) fires when the call recording finishes processing, carrying a short-lived download URL on success. It is independent of `session.finalized` and may arrive before or after it.
  * Webhook settings UI gains a multi-select with per-event tooltips describing the trigger and payload fields.
  * New API reference at [Post Webhooks](/en/api-reference/webhook/initial-setup) covers configuration, payload schemas, delivery semantics, and an end-to-end receiver example.
</Update>

<Update label="April 2026" date="2026-04-12" tags={["Deprecation"]}>
  ### Legacy API keys deprecated — sunset 2026-05-10

  * Legacy project-scoped API keys (`sk_` and `buzz_live_` prefixes) and the `x-api-key` header are deprecated and **stop working on 2026-05-10**.
  * The old `/knowledgebases/*` route is deprecated; use `/v1/projects/:projectId/knowledgebases/*`.
  * All external integrations should migrate to a Developer Key (`dk_` prefix) authenticated as `Authorization: Bearer dk_...`. Developer Keys can be created in **Developer Keys** from your account menu.
  * See the [Legacy API Key migration guide](/en/migrations/2026-04-legacy-api-keys) for step-by-step instructions.
