 # @lemoncode/quickmock-vscode-extension
 
+## 0.2.0
+
+### Minor Changes
+
+- 3cd4892: Toolbar's **New** button now creates a real `.qm` file when running inside the VS Code extension instead of just clearing the canvas.
+
+### Patch Changes
+
+- b7f9cf1: Fix editor failing to load files opened from outside the workspace. The webview HTML was assigned before registering `onDidReceiveMessage`, causing a race where the initial `READY` / `WEBVIEW_READY` message from the app could be lost and the file content never delivered. The listener is now registered before the HTML assignment.
+
 ## 0.1.0
