 # Change Log
 
+## [0.1.0] - 2025-09-16
+
 ### Added
+
+- Webview preview with live validation
+- Replace/Skip/Cancel prompt when target items already exist (uses Trash for Replace)
+- Support for JSON file leaves as string file types (e.g., "route": "ts")
+- Safer, remote-ready filesystem via `vscode.workspace.fs`
+- Tree symbol constants for consistent, readable Unicode output (├──, └──, │)
+
+### Changed
+
+- Plain Text parser is now strict: requires connectors, enforces single root directory, consistent indentation, and ignores the first line as header
+- Plain Text creation asks confirmation before proceeding if input is invalid
+- Formatter outputs readable tree; JSON output reflects new file-leaf format
+- Webview UI modernized (two-column layout, status badge, copy preview, clear input)
+
+### Fixed
+
+- Various encoding issues in tree drawing by using Unicode consistently
+- Type-safe configuration access and better error handling
+
+### Previous Versions
