 CHANGES
 
-8.6.0 (Jun xx, 2025)
+8.7.0 (Aug 1, 2025)
+- Added support for feature flag prerequisites. This allows customers to define dependency conditions between flags, which are evaluated before any allowlists or targeting rules.
+
+8.6.0 (Jun 17, 2025)
 - Added support for rule-based segments. These segments determine membership at runtime by evaluating their configured rules against the user attributes provided to the SDK.
 - Added support for feature flag prerequisites. This allows customers to define dependency conditions between flags, which are evaluated before any allowlists or targeting rules.
