<Update label="v1.1.0" description="17 Sept 2026">
  `data-sync`

  Added Data Sync support for automations, campaigns, campaign languages, custom fields, groups, segments, subscribers, timezones and webhooks, so these collections can be kept in sync and paged through in full rather than fetched one page at a time.
