 # Changelog
 
+## 2024-11-24 - 3.2.2 - fix(core)
+Refactor Bucket class for improved error handling
+
+- Ensured safe access using non-null assertions when finding a bucket.
+- Enhanced fastPut method by adding fastPutStrict for safer operations.
+- Added explicit error handling and type checking in fastExists method.
+
+## 2024-11-24 - 3.2.1 - fix(metadata)
+Fix metadata handling for deleted files
+
+- Ensured metadata is correctly stored and managed when files are deleted into the trash.
+
+## 2024-11-24 - 3.2.0 - feat(bucket)
+Enhanced SmartBucket with trash management and metadata handling
+
+- Added functionality to move files to a trash directory.
+- Introduced methods to handle file metadata more robustly.
+- Implemented a method to clean all contents from a bucket.
+- Enhanced directory retrieval to handle non-existent directories with options.
+- Improved handling of file paths and metadata within the storage system.
+
+## 2024-11-18 - 3.1.0 - feat(file)
+Added functionality to retrieve magic bytes from files and detect file types using magic bytes.
+
+- Introduced method `getMagicBytes` in `File` and `Bucket` classes to retrieve a specific number of bytes from a file.
+- Enhanced file type detection by utilizing magic bytes in `MetaData` class.
+- Updated dependencies for better performance and compatibility.
+
 ## 2024-11-18 - 3.0.24 - fix(metadata)
 Fix metadata handling to address type assertion and data retrieval.
