 # Changelog
 
+## 2025-11-30 - 2.0.2 - fix(dees-stepper)
+Make step validation abortable and cancel active step listeners when navigating
+
+- Extend IStep.validationFunc signature to accept an optional AbortSignal so validation handlers can be cancelled.
+- Store an AbortController on the selected step and pass its signal into validationFunc when invoked.
+- Abort the step's AbortController when navigating to the previous or next step to cancel any active listeners or async operations.
+
 ## 2025-11-30 - 2.0.1 - fix(dees-stepper)
 Improve dees-stepper visual style and transitions
