+1. **Version Update**:
+   - Updated version number from 0.3.7 to 0.3.71.
+
+2. **Crawler Enhancements**:
+   - Added `sleep_on_close` option to AsyncPlaywrightCrawlerStrategy for delayed browser closure.
+   - Improved context creation with additional options:

+
+3. **Error Handling Improvements**:
+   - Enhanced error messages in AsyncWebCrawler's `arun` method.
+   - Updated error reporting format for better visibility and consistency.
