## 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](/v1/docs/mapp-engage-ios-sdk-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.

**Package Managers**

- CocoaPods
- Swift Package Manager (SPM)
