Release 26.1.0

• OSM (On-site Messaging): Upgraded to Klarna Web SDK v2. Installment messaging now refreshes dynamically on the checkout page when the purchase amount changes. Fixes for OSM display and width on bundles and product sets.

• KEC (Klarna Express Checkout): One-step payments added for direct (non-PSP) merchants. Interoperability data moved from session to custom object KlarnaInteroperabilityData; new job CleanupKlarnaInteroperabilityData removes expired records (e.g. 24h). RefArch/RefArch Global: new slot definitions; OSM/KEC button visibility on iPad and payment option on checkout remain configuration-dependent.

• Metadata and API: Integrator and originator metadata added to every request: Web SDK initialization (KP, KEC, SIWK) and server-side API calls (payments, sign-in, webhook). Fix for red promo messages and social icons on bundles/product sets.

Upgrade: Deploy the new custom type and job with the cartridge; schedule the cleanup job if you use interoperability data. Re-test OSM if you use custom styling (Web SDK v2).
