  • Added output schemas to 37 actions for improved field mapping during configuration
  • Added inline action calling support to the Get Account, Get Campaign, Get Event, Get Image, Get List, Get Profile, Get Segment, Get Template, and List Accounts actions for improved example output during configuration
  • Added opt-in batching to the New and Updated Campaigns and New and Updated Profiles and Lists triggers, dispatching each changed record individually or in configured batches so large backlogs drain in one recurrence; enabling it changes the shape a downstream step receives
  • Added an optional Look-back Date input for performing an initial sync of records on the New and Updated Campaigns and New and Updated Profiles and Lists triggers. The initial sync backfills every record modified on or after the specified date, seeding each once; later recurrences are unaffected. Leave it empty to start from the first recurrence with no backfill
  • Fixed the New and Updated Campaigns and New and Updated Profiles and Lists triggers reporting no changes on every recurrence, so new and updated records never reached the flow
