Version 6.1.0

Released: 24 September 2025

Enhancements

  • Bulk Custom Attribute Update: Added the bulk-set method setCustomAttributtes:withCompletionHandler: (note: the public-header symbol contains a known typo — Attributtes with a double t) for updating multiple custom attributes in a single call. This improves efficiency and reduces the number of individual attribute update calls needed. See Custom Attributes.

  • Alias Update with Resend Option: Introduced setDeviceAlias:withResendAttributes:withCompletionHandler:, allowing developers to control whether all previously set custom attributes are re-synced with the backend together with the alias change.

  • Automatic Attribute Resync: When a new alias value is provided and withResendAttributes is set to YES, the SDK automatically triggers a resynchronization of all previously defined custom attributes with the backend.
