 ### Implementation Details
 
-This release implements lightweight PSS (TopN, opt-in/out, allowlist/denylist, power capping) for governance flexibility while removing advanced PSS features that add unnecessary complexity.
+This release retains only the minimal TopN parameter for governance control, removing all other PSS complexity.
 
 The VSCMatured packet removal is an optimization that reduces IBC traffic. The provider and consumer no longer need to acknowledge validator set changes, simplifying the state machine without compromising security guarantees.
