SDK Compatibility Matrix
Optimizely follows the Semantic Versioning standard when upgrading and releasing our SDKs and Clients. We are always working to add support for new SDKs and touchpoints, and we frequently enhance our existing SDKs to make them as idiomatic, performant and easy-to-use as possible.
As a result, the minimum version support for some application and SDK features may vary. The following tables lists cases where version support for features differ. For a complete version history of any given SDK, the changelogs on their Github repos remain the source of truth.
