+## 2026-03-02 - 2.2.0 - feat(actions)
+add action context for safe nested dispatch with depth limit to prevent deadlocks
+
+- Introduce IActionContext to allow actions to dispatch sub-actions inline via context.dispatch
+- Update IActionDef signature to accept an optional context parameter for backward compatibility
+- Add StatePart.createActionContext and MAX_NESTED_DISPATCH_DEPTH to track and limit nested dispatch depth (throws on circular dispatchs)
+- Pass a created context into dispatchAction so actionDefs can safely perform nested dispatches without deadlocking the mutation queue
+- Add tests covering re-entrancy, deeply nested dispatch, circular dispatch depth detection, backward compatibility with actions that omit context, and concurrent dispatch serialization
+
 ## 2026-02-28 - 2.1.1 - fix(core)
 serialize state mutations, fix batch flushing/reentrancy, handle falsy initial values, dispose old StatePart on force, and improve notification/error handling
