SDK bug fixes: Node.js v5.0.5, PHP v4.0.14, Python v4.0.11

Fixed

  • Process endpoints — duplicate_email_id is now typed as a string (URL to a CSV file) instead of an integer. The legacy in_process status value is now handled correctly across all SDKs.
  • Event endpoints — contact_properties and event_properties now accept boolean values in createEvent and createBatchEvents.
  • Contact endpoints — attributes now accepts plain integers in createContact and updateContact. PHP users no longer need to cast integers to float.
