+### Breaking Changes
+
+- **`data-browser-use-ignore` → `data-page-agent-ignore`** - DOM ignore attribute renamed to match the project identity

+
+### Features

+
+### Improvements
+
+- Default `maxSteps` changed from 20 to 40 for better for complex tasks out of the box
+- Added 400ms wait between agent steps for page reactions
+- Increased click wait time (100ms → 200ms) for more reliable interactions
+- Removed debug `console.log` statements from scroll actions
+- Reset observations on new task start
