+## 2025-04-25 - 6.2.1 - fix(AsyncExecutionStack tests)
+Refactor AsyncExecutionStack tests: update non-exclusive concurrency assertions and clean up test logic
+
+- Replace 'toBe' with 'toEqual' for active and pending counts to ensure consistency
+- Simplify default non-exclusive concurrency test by asserting Infinity is non-finite using toBeFalse
+- Adjust test comments and scheduling for clarity in concurrency behavior
+
 ## 2025-04-25 - 6.2.0 - feat(AsyncExecutionStack)
 Improve non-exclusive task management with concurrency limit controls and enhanced monitoring in AsyncExecutionStack.
