# SDK

- [v2.1.3](/purchasely/2.8/faq/migration-guides/sdk/v-2.1.3.md)
- [v2.2.0](/purchasely/2.8/faq/migration-guides/sdk/v2.2.0.md): Until this version, presentations were tied to a specific product. This constraint made multi-product presentations impossible and version 2.2.0 prepares app code to unlock that possibility.
