Release 5.2.0

Changed

• Updates OAuth callback url to support EU region accounts. This is a minimum
  requirement for any accounts in Klaviyo's EU region.

Release 5.1.1

Added

• Include change_status_at on packaged newsletter subscriber payloads so
  historical consent sync can backdate list consent.

Release 5.1.0

Added

• New GET /V1/klaviyo/reclaim/plugin-settings endpoint that returns the
  extension's configured plugin settings for a given store (passed as store_id),
  to speed up support troubleshooting. Sensitive values (Private Klaviyo API Key,
  Webhook Secret) are reported as PRESENT/NULL rather than exposed.

Fixed

• Resolved warnings for PHP 8.5
• Fixed a PHP 8.5 deprecation (array_key_exists() called with a null key) in
  ScopeSetting::getStoreIdKlaviyoAccountSetMap() for stores with no Klaviyo
  Public API Key configured

Release 5.0.0

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.

Release 4.4.4

Changed

• Update Klaviyo V3 API revision to 2026-04-15.

Fixed

• Fixed race condition for adding profiles to a list, retries subscription if we
  attempt to create a profile that already exists.

Release 4.4.3

Added

• Adds AddedItemImageUrl to Added To Cart event payload

Fixed

• Added fallback image selection for Added To Cart events to fix cases where
  there is no "small_image" set on the product. This greatly reduces the
  possibility that "AddedItemImageUrlKey" will be set to null or "no_selection"

Release 4.4.2

Added

• Add isKlaviyoEnabled to product/viewed.phtml.

Changed

• Update Klaviyo V3 API revision to 2025-10-15

Fixed

• Ensure Controller/Checkout/Email.php loads proper classes on frontend.

Release 4.4.1

Fixed

• Removes escapeJs call that was preventing Viewed Product events from syncing
  successfully in 4.4.0

Release 4.4.0

Added

• Add 'kl_parent_ids' extension attribute in product requests.

Fixed

• null argument to str_replace() caused by getPrice() fallback return of null
  instead of "0".

Release 4.3.1

Fixed

• BUGPORT-8326: Formatted $value field in Viewed Product snippet causes API
  error in latest extension.
