   ```
+
+- Added `asv` benchmarking and profiling support in `pyqasm`. ([#258](https://github.com/qBraid/pyqasm/pull/258))
 - Added a workflow to track changes in the `docs/_static/logo.png` file to prevent unnecessary modifications. ([#257](https://github.com/qBraid/pyqasm/pull/257))
 
+
 ### Improved / Modified
 - Modified if statement validation to now include empty blocks as well. See [Issue #246](https://github.com/qBraid/pyqasm/issues/246) for details. ([#251](https://github.com/qBraid/pyqasm/pull/251))
