The Klarna Mobile SDKs follow semantic versioning MAJOR.MINOR.PATCH:

• MAJOR: a major version increment indicates incompatible and breaking changes.
• MINOR: a minor version increment indicates added functionality that is backwards compatible.
• PATCH: a patch version increment indicates backwards-compatible bug fixes.

We recommend staying up to date with the latest SDK versions to take advantage of new features, improvements, and bug fixes.

Klarna does not support bug fixes to earlier MINOR or PATCH SDK versions. If you find bugs in an older MINOR or PATCH version, we recommend updating to the latest available SDK.  Older minor versions of the SDK continue to be available for use, but won’t receive any additional updates.

Make sure to stay informed about Mobile SDK version changes (iOS, Android) and add the new version to your project.  As part of our security policy, each version of the Mobile SDK is considered deprecated one year after the version was released.

• Only SDK versions released within the last 12 months are considered officially approved by Klarna.
• Early Deprecation: SDK versions may be deprecated earlier than 12 months if critical vulnerabilities are identified that impact the confidentiality, integrity, or availability of the service. In such cases, Klarna will provide clear and timely communication.
• Obsolete Integrations: Partners are responsible for any issues, including security breaches, resulting from the use of outdated or unsupported SDK versions.
• Right to Deactivate: Klarna reserves the right to disable integrations using deprecated SDK or OS versions, especially when they pose an identified security risk.

By keeping your integration up to date, you ensure continued compatibility, access to the latest features, and the highest level of security for your users.
