2.4.1 (June 3, 2025)
- Bugfix - Improved the Proxy fallback to flag spec version 1.2 to handle cases where the Proxy does not return an end-of-stream marker in 400 status code responses.

2.4.0 (May 27, 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.
