 ### Features
 * Backported `HARD_STRICT` priority mode from #279 for stricter priority queue polling on the 3.x line
+* Added typed/generic message parameter support — listeners can now declare strongly-typed message parameters and rely on `GenericMessageConverter` for automatic deserialization
 
 ### Fixes
 * Optimized hard-strict polling queue availability checks to avoid full list and sorted-set reads
