<Update label="v1.2.0" description="30 Sept 2026">
  `new-events`

  Added webhook event support for workflow-completed and job-completed, with a setup guide. StackOne registers the outbound webhook on the configured CircleCI project when the account is connected and removes it on disconnect. Two new optional connection fields support this - Project ID, which scopes the webhook, and Webhook Signing Secret, which CircleCI uses to sign each delivery. Accounts that do not use events are unaffected.
</Update>

<Update label="v1.1.0" description="21 Sept 2026">
  `data-sync` `new-feature`

  Enabled scheduled data sync on List Collaborations, so the set of organizations the connected user belongs to can be kept in sync and read without calling CircleCI on every request. It refreshes in full each run, because /me/collaborations returns the whole set in one call and exposes no updated-since filter. No other list action qualifies - every other collection endpoint in the CircleCI API requires an organization or project scope, which a sync schedule cannot enumerate.
