 # Changelog
 
+## 0.5.0: Rework (BREAKING CHANGE)
+- Improved code consistency: return values are now always **lists** when containing multiple objects.
+- **Simplified the package**: Removed the default waiting period for update checks.
+  - It is now the **developer's responsibility** to decide when to check for updates. A separate independent function may be introduced later.
+  - The last update check is still saved in the config and returned as a `time.time()` object.
+
+---
 
 ## 0.4.0: Rework (BREAKING CHANGE)
 - The log file is now a JSON file, allowing it to store multiple package names, versions, and last update timestamps.
