 # Changelog
 
+## 2025-04-30 - 2.3.2 - fix(object)
+Update toHaveProperty matcher to support nested property paths using dot notation
+
+- Changed toHaveProperty implementation to split property strings on '.' and traverse nested objects
+- Fixed value comparison for nested properties by comparing the final drilled value instead of direct property access
+- Added tests for nested property access in test/propertyPath.ts
+
 ## 2025-04-30 - 2.3.1 - fix(readme)
 Improve README documentation with detailed 'Why SmartExpect' benefits section
