+## [1.1.0] - 2026-04-22
+
+### Added
+
+- `UpdateWebhookOptions.url()` — matches the renamed API field on `PUT /webhooks/{id}`
+
+### Changed
+
+- Webhook event types are now namespaced (e.g. `message.delivery`, `engagement.click`, `generation.generation_failure`). The server emits and accepts the namespaced form on both `POST` and `PUT`. Update any hard-coded event strings in `CreateWebhookOptions.events` / `UpdateWebhookOptions.events`.
+
+### Deprecated
+
+- `UpdateWebhookOptions.target()` / `getTarget()` — use `url()` / `getUrl()`. The builder still accepts `target` for source compatibility and serializes it as `url`, so existing callers keep working.
