Added

WhatsApp consent collection at checkout via a new unified Mobile consent
group. Merchants choose to collect consent for SMS, WhatsApp, or both, and a
single mobile checkbox at checkout drives per-channel subscriptions in Klaviyo.

Changed

Replaced the SMS consent admin group with a unified Mobile group. Existing SMS
settings are migrated to the new paths on upgrade; custom label and disclosure
copy is preserved.
Consent submission at order placement now uses the V3
/api/profile-subscription-bulk-create-jobs/ endpoint instead of the legacy
custom webhook.
Phone numbers collected at checkout are now normalized to E.164 before being
sent to Klaviyo.

Removed

Support for PHP versions below 8.1. The plugin now requires PHP 8.1 or later,
aligning with Magento 2.4.5+. Merchants on PHP 7.x must upgrade their PHP
runtime before installing this release.
