 # Changelog
 
-## 2.0.1 - 2024-08-07
+## 1.2.1 - 2024-08-07
 
 1. The client will fall back to the `/decide` endpoint when evaluating feature flags if the user does not wish to provide a PersonalApiKey.  This fixes an issue where users were unable to use this SDK without providing a PersonalApiKey.  This fallback will make feature flag usage less performant, but will save users money by not making them pay for public API access.
